Purpose: To compare refractive outcomes of the foldable intraocular lens sutureless scleral fixated sutureless (Carlevale® FIL-SSF) with the iris-claw lens (Artisan®)., Methods: This retrospective study included consecutive patients who underwent a FIL-SSF implantation or an iris-claw implantation between January 2020 and November 2022 in the ophthalmology departments of Hospices Civils de Lyon (France)., Results: A total of 271 eyes from 265 patients were included: 96 eyes in the FIL-SSF group and 175 eyes in the iris-claw group. At 6 months, the mean (SD) surgically induced astigmatism (SIA) was significantly lower in the FIL-SSF group with 0.3 (1.8) diopters against 0.8 (2.1) diopters in the iris-claw group (p = 0.01). The mean (SD) refractive error was also lower for the FIL-SSF group with 0.1 (1.2) diopters versus 0.5 (1.6) diopters in the iris-claw group (p < 0.001). The mean best corrected visual acuity at 6 months was not significantly different between FIL-SSF and iris-claw lens with 0.47 (0.58) logMAR and 0.39 (0.55) logMAR, respectively (p = 0.12). However, the mean (SD) operative time was longer for FIL-SSF implantation in comparison to iris-claw implantation (59.8 (21.1) minutes versus 41.9 (24.4) minutes, respectively (p < 0.001)). The rate of postoperative complications was similar between the two techniques., Conclusion: This study shows that FIL-SSF achieves better refractive results than iris-claw lens, with a similar rate of postoperative complications. As a relatively new implantation technique, there is a learning curve required to reduce operating time., Key Messages: What is known? Multiple surgical options for correcting aphakia in the absence of capsular support can be used. Currently, foldable intraocular lens sutureless scleral fixated sutureless (FIL-SSF, Carlevale®) and iris-claw (Artisan®) implants are the two preferred options, but there is no consensus on the best technique to adopt. What is new? We showed that FIL-SSF has a significantly lower surgically induced astigmatism compared to the iris-claw implant. Similar rate of postoperative complications was found between these two techniques. Future studies with a longer follow-up period are needed to ascertain its tolerance., Competing Interests: Declarations Ethical approval An international review board approved the study (Ethics Committee of the French Society of Ophthalmology, IRB 00008855 Société Française d’Ophtalmologie IRB#1).

Purpose: To describe the incidence, complications and management of reverse pupillary block (RPB) after implantation of Carlevale intraocular lens (IOL)., Design: Multicenter, retrospective, cross-sectional study., Participants: Of a sample of 128 patients that had undergone Carlevale IOL implantation, 19 patients were found to present RPB., Methods: Nineteen patients with RPB after Carlevale IOL implantation were evaluated and treated with laser peripheral iridotomy (LPI)., Main Outcome Measures: Demographic data (age and gender), data on preexisting medication, axial length (Zeiss IOLMaster 500 and Zeiss IOLMaster 700), presence of pseudoexfoliation material, presence of RPB (anterior segment swept-source SS-OCT Anterion, Heidelberg Engineering), presence of macular edema (Irvine Gass syndrome, OCT Spectralis, Heidelberg Engineering), anterior chamber depth (ACD) before and after LPI, best-corrected visual acuity (BCVA) before and after LPI, and intraocular pressure (IOP) before and after LPI were analyzed., Results: An incidence of RPB of 14.8% was found. The prevalence of pseudoexfoliation syndrome was 21.1%, and 42.1% of patients presented an axial length >24.00 mm. Mean pre-LPI ACD was 4.78 ± 0.465 mm and post-LPI ACD was 4.23 ± 0.404 mm, a statistically significant increase of 0.54 mm (P < 0.001; 95% confidence interval, 0.26-0.83) of ACD was observed. There were no differences between pre- and post-LPI BCVA. Pre-LPI IOP was 17.10 (range, 12-34) mmHg and post-LPI IOP was 14.47 (range, 10-21) mmHg, (P = 0.391). Cystic macular edema (Irvine Gass) was identified in 4 of 19 patients, reporting an incidence of 21.1% in RPB cases., Conclusions: Reverse pupillary block is a relatively common complication after Carlevale lens implantation, which may be associated with an increase of macular edema incidence but does not clearly correlate an increase of IOP. Our hypothesis is that indentation of the sclera induces a posterior rotation of the peripheral iris, causing RPB. Our results encourage looking over the Carlevale IOL implantation technique to consider a routinely intraoperative surgical peripheral iridotomy to avoid RPB and its further complications., Financial Disclosure(s): The authors have no proprietary or commercial interest in any materials discussed in this article., (Copyright © 2024 American Academy of Ophthalmology.

Purpose: To report the cumulative incidence of complications and to describe refractive error and visual acuity (VA) outcomes in children undergoing secondary intraocular lens (IOL) implantation after previous surgery for nontraumatic cataract., Design: Pediatric cataract registry., Participants: Eighty children (108 eyes: 60 bilateral, 48 unilateral) undergoing lensectomy at younger than 13 years of age., Methods: Annual data collection from medical record review through 5 years after lensectomy., Main Outcome Measures: Cumulative incidence of newly emergent complications after secondary IOL implantation; refractive error and VA by 5 years after lensectomy., Results: Median follow-up after secondary IOL implantation was 2.7 years (interquartile range [IQR], 0.8-3.3 years; range, 0.6-5.0 years) for bilateral and 2.1 years (range, 0.5-6.4 years) for unilateral cases. A common complication after secondary IOL implantation was a glaucoma-related adverse event (GRAE; glaucoma or glaucoma suspect); the cumulative incidence was 17% (95% confidence interval [CI], 3%-29%) in bilateral cases and 12% (95% CI, 0%-23%) in unilateral cases. The cumulative incidence of surgery for visual axis opacification was 2% (95% CI, 0%-7%) for bilateral cases and 4% (95% CI, 0%-10%) for unilateral cases. The median prediction error within 90 days of implantation was 0.88 diopter (D; IQR, -0.50 to +3.00 D) less hyperopic than intended among 21 eyes for bilateral cases and 1.50 D (IQR, -0.25 to +2.38 D) less among 19 unilateral cases. The median spherical equivalent refractive error at 5 years (at a median of 5.1 years of age) in eyes receiving a secondary IOL was +0.50 D (IQR, -2.38 to +2.94 D) for 48 bilateral cases and +0.06 D (IQR, -2.25 to +0.75 D) for 22 unilateral cases. Median monocular VA at 5 years was 20/63 (IQR, 20/50-20/100) for bilateral cases (n = 42) and 20/400 (IQR, 20/160-20/800) for unilateral cases (n = 33)., Conclusions: Eyes with secondary IOL implantation have a risk of developing new GRAEs. Five years after lensectomy (approximately 2.5 years after secondary IOL implantation), the average refractive error was less hyperopic than desired given the anticipated further myopic shift before refraction stabilizes., Financial Disclosure(s): Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article., (Copyright © 2024 American Academy of Ophthalmology.

Purpose: This study aims to analyze the incidence of pseudophakic macular edema (PME) and the role of contributing risk factors following prepupillary or retropupillary implantation of iris-claw lenses., Methods: This retrospective cohort study included patients who underwent iris-claw intraocular lens implantation over a 16-year period at the University Hospital of Santiago de Compostela, Spain. The presence of risk factors for PME was recorded, and surgical outcomes included visual acuity, macular OCT scans, and description of complications., Results: A total of 148 eyes from 147 patients were included. Seventy-nine eyes (54.4%) underwent prepupillary iris-claw lens implantation and 69 eyes (46.6%) underwent retropupillary implantation. The mean age of the patients was 68.9 ± 17.2 years. The incidence of PME post-surgery was 23.0% (26.6% prepupillary and 18.8% retropupillary), and the mean time between surgery and diagnosis was similar for both locations (4.8 and 4.7 months, respectively). PME recurred in 33% of the patients, reaching a high rate of 72.7% when the lens location was prepupillary. The mean best-corrected visual acuity was 0.66±0.55 logMAR preoperatively and 0.38±0.50 logMAR postoperatively. Postoperative complications occurred in 29 patients (19.6%)., Conclusion: PME following iris-claw lens implantation tends to be more frequent and recurrent when the location is prepupillary. Planning for iris-claw lens surgery should consider the risk factors for the development of PME., Competing Interests: The authors declare no conflict of interest related to this work., (© 2024 Tourino-Peralba et al.)

Background: A modified surgical technique of sutured scleral fixated intraocular lens (SSF-IOL) was applied in a patient with post-traumatic aniridia and aphakia., Case Presentation: A 51-year-old man was referred to our clinic with decreased vision (finger count) in his right eye. This patient had previously undergone primary repair of the ruptured globe and pars plana vitrectomy to manage ocular trauma in the same eye. On presentation, the best corrected visual acuity in his right eye was 20/40. The slit lamp examination of his right eye revealed loss of total iris and lens. Corneal endothelial cell density was 1462 cells/mm 2 . Fundoscopic examination of the right eye revealed a retinal attachment. For IOL implantation, a rigid poly methyl methacrylate IOL was used with a 2-point scleral fixation performed using a polypropylene suture. One year postoperatively, the uncorrected distance visual acuity was 20/32, and the manifest refraction was - 0.5/-1.5 × 130 (20/20). Pentacam revealed that the astigmatism of the anterior corneal surface and the total cornea was 1.1 D (axis: 59.8°) and 1.0 D (axis: 35.6°), respectively. The horizontal (3°-183°) cross-section image displayed an IOL with a 1° tilt and 0.425 mm decentration. The patient reported no dysphotopsia or photophobia and was satisfied with the visual results. OPD-scan III revealed that higher-order aberrations in the right eye were slightly higher than those in the left eye. No suture-related or other serious complications were observed., Conclusion: The modified SSF-IOL technique can offer improved visual quality for patients with aniridia and aphakia by ensuring proper IOL positioning and reducing astigmatism., (© 2024.

Lens drop and intraocular lens (IOL) drop can occur after cataract or phacoemulsification surgery, where the IOL is dislocated from the capsular bag into the vitreous cavity. The aim of this study was to investigate the short-term outcomes of implanting a retropupillary iris-claw in patients with IOL drop and lens drop after phacoemulsification. A cross-sectional study was conducted at Santosa Hospital, Bandung, West Java, Indonesia, from January 2020 to December 2023. Patients were divided into two groups: IOL drop and lens drop groups. Total sampling was used, involving 51 patients in the present study, with 27 patients in the IOL drop group and 24 patients in the lens drop group. Data collected included age, sex, eye laterality, the onset of IOL drop or lens drop, intraocular pressure (IOP), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), record of astigmatism change preoperative and postoperative, and postoperative pars plana vitrectomy (PPV) complications. Our data indicated that the UDVA significantly improved in both IOL drop and lens drop groups after PPV surgery ( p <0.001). However, there were no significant changes in IOP or astigmatism following the surgery in either group. Over one month, both groups showed improved UDVA, decreased IOP, and changes in astigmatism, with no significant differences between groups. Similarly, there was no significant difference in CDVA between IOL drop and lens drop groups. Only four complications were recorded in the present study. Comparing IOL drop and lens drop groups, only an increase in IOP showed a significant difference ( p =0.018). Corneal edema, IOL decentration, and pupil ovalization were not significantly different. In conclusion, retropupillary iris-claw IOL implantation is safe and effective for aphakic patients with complications from phacoemulsification, regardless of whether it is lens drop or IOL drop., Competing Interests: All the authors declare that there are no conflicts of interest., (© 2024 The Author(s).)

Introduction: A novel technique is described employing scleral grooves to facilitate sutureless scleral fixation of the Carlevale intraocular lens (CIL). We describe its use in a series of 47 patients with aphakia., Methods: A retrospective study of all patients with aphakia who underwent CIL implantation with the new technique by a single surgeon during 1 year. The novelty of this technique consists in the creation of two partial-thickness linear sclerotomies (grooves), 180° apart, 2 mm from and parallel to the limbus. In the middle of each groove a full-thickness sclerotomy is performed to facilitate externalization of the CIL anchors. The groove allows the anchor to plug the full-thickness sclerotomy and to rest within the sclera without protrusion. Reported outcomes include pre-operative/post-operative visual acuity, post-operative spherical equivalent and surgical complications. Follow-up was a minimum of 6 months., Results: Forty-eight eyes of 47 patients with aphakia with a mean age of 74 years (range 31-90 years) are included. The commonest causes of aphakia were intraocular lens (IOL) subluxation,with or without exfoliation (54.2%), complicated cataract surgery (29.2%), crystalline lens luxation (6.3%) and trauma (4.1%). All CILs inserted with the new technique stayed successfully in situ during follow-up. Median pre-operative best-corrected visual acuity (0.75 logMAR; range 0.1-2.7) significantly improved to 0.5 logMAR post-operatively (p < 0.001). Moreover, 78% and 65% of the operated cases were within 1.0 and 0.5 diopters, respectively, from intended refraction. The most common complications were transient cystoid macular oedema (8.3%) and transient intraocular pressure rise (8.3%), all of which resolved within 2 months., Conclusions: The proposed modification of sutureless scleral fixation of the CIL appears safe and effective. In our experience it is less time consuming and easier to perform than previous techniques and may therefore offer a useful future option., (© 2024. The Author(s).)

Objective: The aim of this report was to provide a clinical description and clinical, ultrasonographic, and histologic images of a foal with microphthalmia and multiple ocular abnormalities., Animals Studied: A 12-h old Friesian-American Paint Horse crossbred filly presented for blindness, microphthalmia and marked ventral strabismus in both eyes., Procedure: A complete ophthalmic examination was performed. Ultrasound biomicroscopy and B-mode ultrasonography were performed. The globes were submitted for histopathology., Results: Ultrasound biomicroscopy demonstrated a hyperechoic cornea void of the typical epithelium, stroma, and Descemet's membrane layers. The anterior chamber was spanned by thick strands of hyperechoic tissue extending from the iris to the cornea. The lens was not visualized. B-mode ultrasound showed aphakia and mild, mottled echogenicity within the vitreous with no evidence of retinal detachment. On histopathology, both globes were microphthalmic with poorly defined corneal tissue. The anterior chambers were poorly formed and contained lacrimal glandular tissue. Portions of iridal tissue were present, but no lenses were noted. The retinas were segmentally detached and markedly atrophied with areas of retina dysplasia noted., Conclusions: This report provides a clinical, ultrasonographic and histologic description of a rare, congenital condition in a foal characterized by microphthalmia, aphakia, poorly defined corneal tissue, choristomatous differentiation of the anterior segment and retinal dysplasia., (© 2024 American College of Veterinary Ophthalmologists.)

Purpose: To report the long term visual outcomes and complications with use of the novel CM-T Flex scleral fixated intraocular lens (CMT-SFIOL)., Materials and Methods: 116 eyes that underwent CMT-SFIOL were reviewed and 57 eyes with CMT-SFIOL that completed a 2-year follow-up were included. Main outcome measures noted were best-corrected visual acuity (BCVA) and complications. Postoperatively, follow-ups were done at 1 week (1w), 1 month (1 m), 1 year (1y) and 2-year (2y) intervals., Results: 40 (70.17%) of 57 eyes received CMT-SFIOL for surgical aphakia. Mean follow up was 39.77 ± 8.44 months. BCVA for distance & near improved from 1.26 ± 0.84 to 0.76 ± 0.77, 0.50 ± 0.72 and 0.51 ± 0.73 & 1.28 ± 0.58 to 0.98 ± 0.49, 0.92 ± 0.44 and 0.89 ± 0.40 at 1 m, 1y and 2y respectively (p < 0.001 for all). At 1w, 10 eyes (17.54%) had corneal edema (CE) and 8 eyes (14.03%) had anterior chamber (AC) reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had vitreous hemorrhage (VH). At 1 m, 3 eyes (5.26%) had CE and 5 eyes (8.77%) had AC reaction. Two eyes (3.50%) had IOP > 30 mm Hg and 1 eye (1.75%) had VH. Cystoid macular edema was noted in 3 eyes (5.26%). At 1y and 2y, 2 eyes (3.5%) and 1 eye (1.75%), had CE. No decentration, dislocation, haptic exposure or retinal detachment was noted. No eyes required resurgery., Conclusion: CM-T Flex SFIOL is an effective method to correct aphakia, with reliable and safe long-term results., (© 2024.

Introduction: The purpose of our study was to compare the safety and efficacy of two scleral fixation intraocular lens (IOL) methods of four-point scleral fixation (Akreos AO60) and the Yamane technique (AcrySof MA60AC)., Methods: This prospective, randomized study was conducted at the Military Institute of Medicine-National Research Institute in Warsaw between 2021 and 2023. We compared both groups for cause of aphakia, ocular history, refractive status, and complication., Results: Our study included 50 eyes from 47 patients. Four-point fixation was performed in 25 eyes (group 1), and the Yamane technique was used in 25 eyes (group 2). Surgical time was 24.1 min ± 8.9 in group 1 and 25.1 min ± 9.9 in group 2 (p > 0.05). The postoperative BCVA (best-corrected visual acuity) for group 1 and group 2 at 1 year's observation was 0.10 ± 0.15 and 0.09 ± 0.17 logMAR, respectively (p > 0.05). Postoperative total refractive error (RE) was - 0.06 ± 0.71 diopters (D) for four-point scleral fixation and 0.83 ± 0.70 D for Yamane technique (p < 0.05). Endothelial cell density (ECD) loss was 0.9% in group 1 and 3.5% in group 2 (p > 0.05). Bleeding into the anterior chamber and vitreous body was more frequent in the group of patients operated on with the use of the Yamane technique (10 cases, 20%, p = 0.01). IOL displacement was found in one case (2%) in group 2., Conclusions: Both analyzed techniques are well tolerated and ensure good refractive results (extremely predictable in four-point scleral fixation) and have a similar safety profile. Four-point scleral fixation of IOL would appear to be safe, effective and beneficial for young, active patients, especially after trauma or recurrent subluxation., Clinical Trial Registration: ClinicalTrials.gov identifier NCT06389643., (© 2024.

Purpose: Evaluation of anterior segment parameters using the Scheimpflug corneal topography 1 year after surgery in patients who underwent sutureless scleral fixation intraocular lens (SFIOL) implantation using the modified Yamane technique and retropupillary iris-claw intraocular lens (RPIOL) implantation., Methods: A total of 60 eyes from 57 patients who underwent sutureless SFIOL implantation and 57 eyes from 52 patients who underwent RPIOL implantation were included. Anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), anterior-posterior corneal astigmatism, and keratometric values were assessed using the Scheimpflug corneal topography (Pentacam HR, Germany)., Results: There was no statistically significant difference in postoperative UCVA and BCVA between the sutureless SFIOL and the RPIOL group (p = 0.236, p = 0.293, respectively). While there was no statistically significant difference in postoperative IOP between the two groups (p = 0.223), a statistically significant decrease in IOP was observed in both groups (p < 0.001). While there was no statistical difference between the sutureless SFIOL group and the RPIOL group in terms of spherical value (p = 0.441) and spherical equivalence (p = 0.237), there was a statistically significant difference in cylindrical value (p < 0.001). While there was a statistical difference in anterior astigmatism (p < 0.001), there was no statistical difference in posterior astigmatism (p = 0.405). There was no statistical difference in terms of ACV, ACD, and ACA between the sutureless SFIOL and the RPIOL group (p = 0.812, p = 0.770, p = 0.401, respectively)., Conclusion: In this study, although there was a statistical difference in cylindrical value and anterior corneal astigmatism between the sutureless SFIOL and RPIOL groups, vision was not affected. According to this study, sutureless SFIOL and RPIOL are two successful methods in terms of visual acuity, anterior segment, and keratometry outcomes in aphakic patients after phacoemulsification., (© 2024.

Purpose: After infantile cataract surgery, axial elongation, induces a myopic shift that cannot be fully compensated by corneal flattening and the rate is unpredictable owing to the non-linear growth of the eye. The current prospective study assesses the myopic shift and visual outcomes in children undergoing cataract surgery in infancy over a follow-up period of 5 years., Materials and Methods: A prospective study conducted at a tertiary eye care center to evaluate the five-year myopic shift, refractive and visual outcomes in infants, who underwent surgery for congenital cataract in infancy. The visual acuity, myopic shift and biometric changes are compared between the aphakia and pseudophakia group., Results: The mean best-corrected visual acuity (BCVA) recorded in logMAR at 5 years for aphakia group was 0.92±0.44 and for pseudophakia group was 0.66±0.42. (pvalue: 0.002102). The myopic shift was noted to be -5.9+/-5.16 in the aphakia group whereas it was -9.01+/- 3.11 in the pseudophakia group ( P value= 0.002101) at 5 years after surgery for infantile cataract., Conclusion: IOL implantation in eyes of infants undergoing cataract surgery is feasible in eyes that strictly satisfy the pre-operative inclusion criteria and the visual outcomes in these eyes are better compared to aphakia group at 5 years follow up. Eyes with primary IOL implantation had a higher myopic shift compared to ones without primary IOL implantation. Eyes undergoing primary IOL implantation, need higher under correction compared to the current available formulae., Competing Interests: The authors declare that there are no conflicts of interests of this paper., (Copyright: © 2024 Taiwan J Ophthalmol.)

Purpose: The main aim of this study was to evaluate the type, parameters, loss and complications of contact lenses (CLs) in the treatment of paediatric aphakia over a 10-year period., Methods: This retrospective multicentre chart review included the files of aphakic CL wearers under the age of 9 years old that were treated between 2008 and 2018. Patients with traumatic aphakia and scarring of the cornea were excluded. The following data were collected; demographic data, cataract type (congenital or secondary), CL type, parameters and wearing time, reason for replacement and discontinuation of the CLs, visual acuity (VA), prophylactic use of antibiotics (ABs), and complications., Results: Ninety-one aphakic children (132 eyes) were fitted with soft CLs. The median age of cataract extraction was 10.50 weeks (interquartile range (IQR) 7,15) in the congenital cataract group and 112 weeks (IQR 41,285) in the secondary cataract group. At the initial fitting a silicone elastomer CL was fitted in 86 % and a silicone hydrogel CL in 12 %, the remaining 2 % were mixed CL types. The median CL power at baseline was + 29 D (IQR 25,32) and after 3 years of wear the median power had shifted significantly to + 20 D (IQR 17,26), P < 0.001. A total of 1083 extra CL replacements were needed of which 414 in the first year of wear. Of these 414 replacements almost half (46 %;n = 191) were due to loss of the CL. Complications developed in 8 (9 %) cases and 7 (8 %) patients discontinued CL wear., Conclusion: This paper confirms that paediatric aphakia can be successfully treated with soft CLs with low rates of complications and discontinuation encountered. Unscheduled CL replacements due to loss are a concern, especially in the first year, and are straining for both the care giver and medical system. Attentive care and clear information is advised during the first year of CL wear., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 British Contact Lens Association.

Different techniques for artificial iris implantation with or without an intraocular lens, depending on lens status, are described in the literature. We describe a surgical technique for a custom-made artificial iris and toric-intraocular lens intrascleral flange fixation. We modified the "Backpack" artificial iris implantation surgical technique to facilitate an accurate alignment of the toric-intraocular lens in a patient with aphakia, aniridia, and high asymmetric astigmatism secondary to blunt trauma. Two months after the surgery, uncorrected visual acuity was 20/30, corrected to 20/25 with a refraction of -2.00 in the diopter sphere with no residual astigmatism. The artificial iris implant and toric-intraocular lens were well-centered. The patient was satisfied with the visual and cosmetic outcomes. This procedure, however, is not complication-free as our patient developed uveitis and increased intraocular pressure during the postoperative period, which was treated successfully.

Background : The aim of this study was to evaluate the short-term efficacy and safety of the Paul Glaucoma Implant (PGI) in pediatric eyes diagnosed with glaucoma following congenital cataract surgery (GFCS). Methods : A retrospective, single-center, descriptive study was conducted on consecutive children diagnosed with GFCS who underwent PGI implantation between July 2022 and November 2023 at the University Medical Center Mainz. The primary outcome measure was the reduction in IOP at the last follow-up visit. Results : Ten eyes of nine children were included in the study. The mean follow-up time was 7.70 ± 4.22 months (4.68-10.72 months). At the end of the study follow-up, the mean (95% CI) reduction in IOP was -14.8 ± 8.73 mmHg (-8.56 to -21.04 mmHg, p < 0.001). At the last follow-up, 30.0% (3/10) of patients achieved an IOP (intraocular pressure) of ≥6 and ≤21 mmHg with a reduction in IOP of ≥25% without treatment, while 90.0% (9/10) achieved this target IOP regardless of glaucoma medication treatment. The mean number of antiglaucoma medications was significantly reduced from 3.50 (IQR = 1) to 2.0 (IQR = 2, p = 0.01), and the visual acuity logMAR improved from 1.26 ± 0.62 to 1.03 ± 0.48 ( p = 0.04). Only one eye experienced numerical hypotony (4 mmHg) without choroidal detachment or anterior chamber shallowing within the first 24 h. No other adverse events were observed during the follow-up period. Conclusions : PGI implantation significantly lowered IOP and the number of antiglaucoma eye drops with a favorable safety profile in children diagnosed with GFCS, thereby achieving a high rate of qualified surgical success in the short term.

Congenital cataract is among the main causes of treatable vision loss in childhood. The first weeks and months of life are a critical time for the development of vision. Therefore, early cataract surgery and effective multifaceted treatment of the resulting aphakia in the early stages of life are of great value for the management of vision development. Among the treatment models, contact lenses (CL) have an important place in infancy and early childhood up to the age of 2 years. Although good visual gains were not considered very likely, especially in unilateral aphakia, important steps have been taken in the treatment of pediatric aphakia thanks to the surgical techniques developed over time and the increasing experience with optical correction systems, especially CLs. This review examines current developments in the types of CL used in pediatric aphakia, their application features, comparison with other optical systems, the features of amblyopia treatment in the presence of CL, and the results obtained with family compliance to CL wear and occlusion therapy in the light of existing studies., Competing Interests: Conflict of Interest: No conflict of interest was declared by the authors., (©Copyright 2024 by the Turkish Ophthalmological Association / Turkish Journal of Ophthalmology published by Galenos Publishing House.)

Objective: The aim of this paper is to compare the refractive correction effects of rigid gas permeable contact lenses (RGPCL) and spectacle correction in children with aphakia after congenital cataract surgery. Methods: This was a prospective non-randomized controlled trial. Children with aphakic eyes after congenital cataract surgery, who underwent vision correction in the Strabismus and Pediatric Ophthalmology Clinic of Beijing Tongren Hospital affiliated with Capital Medical University from April 2012 to November 2019, were continuously collected. Those who voluntarily chose to wear RGPCL for refractive correction were included in the experimental group. Patients with monocular disease were in trial group 1, and patients with binocular disease were in trial group 2. Patients who chose to wear frame glasses for refractive correction were included in the control group. Patients with monocular disease were in control group 1, and patients with binocular disease were in control group 2. Regional origin, medical history, and family information were collected at the first diagnosis. During the follow-up, adverse reactions occurring during the process of wearing glasses were recorded. The Teller acuity card was used for visual examination to obtain the best-corrected visual acuity and convert it into the logarithm of the minimum resolution angle. The degree of nystagmus was determined according to the amplitude and frequency of nystagmus. Treatment cost, treatment compliance, and the reasons for adopting or not adopting RGPCL were analyzed through a questionnaire completed by the parents of children with RGPCL. Results: A total of 203 children (344 eyes) who underwent congenital cataract surgery were included, including 124 males (210 eyes) and 79 females (134 eyes). The age range was 3 to 36 months. There were 28 cases in the experimental group, including 19 cases in trial group 1 and 9 cases in trial group 2. There were 175 cases in the control group, including 43 cases in control group 1 and 132 cases in control group 2. Except for 6 months of age, the visual acuity of the experimental group was better than that of the control group, and the differences were statistically significant ( P <0.05). The visual acuity of children in trial group 1 was better than that of children in control group 1 at the same age. Among them, at 12 months of age [1.54 (1.27, 1.97), 1.84 (0.97, 2.12)], 18 months of age [1.27 (0.97, 1.84), 1.84 (0.97, 2.12)], 24 months of age [1.54 (1.27, 1.84), 1.84 (0.97, 2.12)], and 30 months old [0.97 (0.66, 1.27), 1.54 (0.66, 2.12)], the difference was statistically significant ( P <0.001). The visual acuity of children in trial group 2 was better than that in control group 2 at the same age. Among them, at 18 months old [1.27 (0.97, 1.54), 1.27 (0.66, 2.12)], 24 months old [0.97 (0.66, 1.27), 1.27 (0.66, 2.12)], and 30 months old [1.27 (0.66, 2.12)], the difference was statistically significant ( P <0.05). The remission rate of nystagmus in the experimental group was 8/9 (8 cases), the remission rate of nystagmus in the control group was 34.40% (32 cases), and the exacerbation rate was 29.03% (27 cases). The average annual cost of the experimental group was 25 125 yuan, and that of the control group was 2 511 yuan. Conclusions: RGPCL is a well-tolerated, safe, and effective treatment for infants and young children. The visual acuity and degree of nystagmus were significantly improved in children who wore RGPCL for aphakia refractive correction after congenital cataract surgery compared with spectacle correction.

Purpose: To identify risk factors for retinal detachment (RD) after open-globe injury (OGI) and evaluate outcomes of RD repair after OGI., Design: Case-control study., Participants: Overall, 769 patients presented with 786 OGIs, which were surgically managed with ≥ 30 days of follow-up. Of the 786 eyes, 223 developed RD, the other 551 served as controls, and RD status of 12 eyes was unknown., Methods: A retrospective chart review was performed of all OGIs presented to the University of Michigan between 2000 and 2022. Multivariable regression identified risk factors for RD after OGI and predictors of poor vision after RD repair. Kaplan-Meier analysis estimated time from OGI to RD., Main Outcome Measure: Predictors of visual outcome after RD repair after OGI., Results: After OGI, 223 (28.4%) of 786 eyes were diagnosed with RD, with > 73% diagnosed within a month. Predictors of RD include posterior injury (zone II vs. I odds ratio [OR], 1.60 [95% confidence interval {CI}, 1.04-2.46]; P = 0.0331; zone III vs. I OR, 2.29 [1.53-3.41]; P < 0.0001), vitreous hemorrhage (OR, 2.29 [1.54-3.1]; P < 0.0001), and presenting acuity worse than count fingers (CFs) (OR, 2.65 [1.69 - 4.16]; P < 0.0001). Retinal detachment repair took place in 142 of 223 eyes. The mean logarithm of minimal angle of resolution visual acuity (VA) improved from 2.3 ± 0.8 to 1.7 ± 0.9 after RD repair at 6-month follow-up, with 51.2% of eyes achieving CF or better vision. Single surgery anatomic success rate was 69.7% and final anatomic success was 88%. Predictors of vision worse than CF include history of ocular surgery (OR, 0.32 [0.11-0.94]; P = 0.039), proliferative vitreoretinopathy (PVR; OR, 0.39 [0.16 - 0.92]; P = 0.032), aphakia (OR, 0.25 [0.08 - 0.77]; P = 0.016), and redetachment (OR, 0.26 [0.1 - 0.63]; P = 0.003)., Conclusions: Most RD occur within the first month after OGI. Patients with posterior injuries, vitreous hemorrhage, or poor presenting VA were more likely to develop RD after OGI. Anatomic success was achieved in the majority, as was final VA of CF vision or better. History of ocular surgery, PVR at time of repair, aphakia, and redetachment were risk factors for a poor outcome., Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article., (Copyright © 2023 American Academy of Ophthalmology.

Clinical Relevance: It is particularly important to perform reasonable and effective optical correction to enable visual development after primary lens removal surgery for congenital cataracts. Aphakic infants need a suitable addition power of prescription (ADD) to help them focus on close visual objects., Background: It is challenging to obtain appropriate ADD power for infants due to poor cooperation and lack of subjective feedback. We aimed to determine the appropriate ADD for aphakic infants using a recently developed smart wearable device called Clouclip., Methods: The study was a cross-sectional, observational pilot study. Twenty-three aphakic infants (aged from 6 months to 3.5 years) were invited to wear a smart wearable device for 7 days consecutively to monitor the near viewing distance in real life. Viewing habits and its associations with the possible influencing factors were investigated based on the data obtained from the device., Results: The average proportion of near viewing time was 77.9% (95% confidence interval (CI) 72.1-83.7%). The average of the median near viewing distance was 23.8 cm (95% CI 20.6 cm-27.0 cm), which corresponded to an ADD of +4.25 D (95% CI + 3.75 D - +4.75 D) spectacle prescription. The height of the child was found to be positively correlated with the median of near viewing distance ( r  = 0.646, p  = 0.001). Age, current ADD, age of cataract extraction surgery and bilaterality or monocularity of the aphakic eyes showed no significant correlation with the aforementioned viewing habits (all p  > 0.05)., Conclusion: By using the novel wearable device, we found the suitable ADD of spectacle prescription for aphakic infants is about +4.25 D. The height of the child was an influencing factor for ADD.

Purpose: This study aims to introduce a new suture method and report surgical outcomes of patients who underwent scleral-fixated intraocular lens (SF-IOL) implantation combined with either pars plana vitrectomy (PPV) or anterior vitrectomy (AV)., Methods: Twenty-three eyes performed SF-IOL implantation combined with PPV (Group 1), and 34 eyes performed SF-IOL implantation combined with AV (Group 2) were included in the study prospectively. The SF-IOL, either polymethyl methacrylate or foldable IOL, was sutured into the sclera using PC-9 sutures in an irregular, knotless, and zigzag-shaped manner. The scleral tunnel was approximately 12-15 mm long, with at least four sharp edges. Suture tips were trimmed within the scleral tunnel. Postoperative outcomes and complications were evaluated., Results: Both groups showed no complications such as suture tip expulsion, suture reaction, IOL dislocation, or increased intraocular pressure during postoperative visits. Group 1 exhibited a statistically significant improvement in visual acuity compared to preoperative values ( P = 0.036 for the 1 st month, <0.001 for the 3 rd month). Similarly, Group 2 demonstrated a statistically significant improvement in visual acuity compared to the preoperative period ( P = 0.001 for the 1 st month, <0.001 for the 3 rd month)., Conclusion: The "irregular, knotless, and zigzag-shaped scleral tunnel suture technique" yielded favorable results in terms of IOL stability and visual acuity. This technique can be safely employed in patients undergoing SF-IOL implantation combined with PPV or AV., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Saudi Journal of Ophthalmology.)

Background: Surgical correction of aphakia without capsular support continues to be a challenge. Improvements in the technology of cataract surgery have provided advancements in techniques in surgical management of aphakia. Locally, we have limited data on the outcomes of the different intraocular lenses used in aphakia., Objective: This study aimed to determine visual outcomes and complications associated with different techniques of intraocular lens implantation in the absence of capsular support., Methods: We reviewed the medical charts of 207 patients who underwent intraocular lens implantation without capsular support. Excluded were patients with incomplete follow up, pediatric patients, and lost records. Best corrected visual acuity at day 1, 1 st month, 3 rd month and 6 th month postoperatively, and the complications were noted., Results: Mean age was 60 and 51% (n=105) were females. The mean follow-up time was 9.33 ± 0.71 months. Loss of capsular support was most frequently caused by intraoperative complication (n=146, 70%) and trauma. Retropupillary fixation iris claw intraocular lens was frequently used (n=93, 44.9%). Across all patients, visual acuities showed excellent outcomes with 20/50 or better. Across IOL types, the most frequent postoperative complication was increase in IOP. Statistically significant results were set at P <0.05., Conclusion: There is a notable preference towards iris claw retropupillary lenses through time. Iris claw lenses showed the shortest operative time. All intraocular lenses used in aphakia showed comparably good postoperative visual acuities, except for the superior visual acuity trend seen among retropupillary iris claw and anterior chamber IOL groups. Complications included elevated intraocular pressures, corneal edema, and pigment dispersion., Competing Interests: Both authors declared no conflict of interest., (© 2024 Acta Medica Philippina.)

Aim: To compare the anatomical and functional results and patient satisfaction following retropupillary implantation of Artisan Aphakia iris-fixated intraocular lens (rAAIF) and sutured scleral fixated intraocular lens (SFIOL). Subjects and methods: We presented a prospective double-arm non-blinded study. Forty-one eyes with acquired aphakia, no age-related macular degeneration, no previous keratoplasty, no combined procedures, no AC reaction (cells, fibrin), normal intraocular pressure, no history of endothelial corneal dystrophy in relatives or fellow eye were included. Indications, complications, corrected distance visual acuity (CDVA), endothelial cell density (ECD), and patient satisfaction score were assessed. Results: Retropupillary AAIF was implanted in 21 (51.22%) eyes and SFIOL in 20 (48.78%) eyes. The most common indication was complicated cataract surgery in 18 cases (43.90%), followed by trauma in 16 (39.02%), and spontaneous dislocation in 7 (17.07%). No difference between rAAIF and SFIOL in terms of sex, laterality (χ=0.13, p =0.72), indications (χ=0.78, p =0.68), previous ocular history, and comorbidities was observed. The complications and the visual outcomes at 6 months postoperatively were similar between the two groups ( p =0.95 and p =0.321, respectively). The ECD loss in the two groups was also similar ( p =0.89). The patient satisfaction score was 58.67±8.80 in the rAAIF and 56.69±11.50 in the SFIOL group, which was statistically similar ( p =0.764). Conclusion: Retropupillary AAIF and SFIOL showed similar results concerning visual acuity, endothelial cell loss, and patient satisfaction. Careful preoperative individual assessment is required to have optimal results with either technique.

Background: Sutureless scleral fixed intraocular lens implantation (SF-IOL) has become one of the mainstream schemes in clinical treatment of aphakic eyes because of its advantages, such as avoiding dislocation of intraocular lens or subluxation caused by suture degradation or fracture and significant improvement of postoperative visual acuity. However, a consensus on the relative effectiveness and safety of this operation and other methods is still lacking. This study aimed to compare the efficacy and safety of sutureless SF-IOL with other methods. Aphakia means that the lens leaves the normal position and loses its original function, including absence or complete dislocation and subluxation of the lens which could cause anisometropic amblyopia, strabismus, and loss of binocular function in children and adolescents. For adults, the loss of the lens could lead to high hyperopia and affect vision. Above all this disease can seriously affect the quality of life of patients., Methods: Literature about sutureless SF-IOL in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, China Technical Journal VIP database, and Wanfang database published from 2000 to 2022 was reviewed. The weighted average difference was calculated by RevMan5.3 software for analysis. Two researchers independently selected the study and used the Cochrane collaboration tool to assess the risk of errors. Cochrane bias risk tool was used to evaluate the quality of evidence. This study is registered on PROSPERO (CRD42022363282)., Results: The postoperative IOL-related astigmatism of sutureless SF-IOL was lower than that of suture SF-IOL, and there was statistical difference when we compared the absolute postoperative spherical equivalent after sutureless SF-IOL and suture SF-IOL. Indicating that the degree of refractive error after sutureless SF-IOL was lower. Meanwhile, the operation time of sutureless SF-IOL was shorter than that of suture SF-IOL. The subgroup analysis showed that the absolute postoperative spherical equivalent and astigmatism values in Yamane technique were lower than those in suture SF-IOL., Conclusion: Sutureless SF-IOL has the advantages of stable refraction, short operation time, and less postoperative complications. However, high-quality literature to compare these technologies is lacking. Some long-term follow-up longitudinal prospective studies are needed to confirm the findings., (© 2023. The Author(s).)

This study aimed to describe a novel modified surgical technique for FIL SSF lens (Rome, Italy: Soleko) implantation. A retrospective study of FIL SSF lens implantation on six eyes of six patients with subluxated or dislocated intraocular lens (IOL). Standard pars plana vitrectomy (PPV) was performed in all patients. The subluxated or dislocated IOL was removed from a 2.4 corneal incision. From the same incision, the folded FIL SSF lens was inserted. Then lens plugs were extremized through a 23G scleral incision inside two 4 mm pockets that were created at the beginning of the operation. In two cases one pocket had to be converted into a triagonal-shaped scleral flap. All scleral pockets were sutured with 7.0 Vicryl suture and the conjunctiva with 7.0 Vicryl. In the follow-up period of six months, the lens is centered and not tilted. The refractive outcome is within the expectations. Visual acuity is improved in all patients. No haptic exposure and no other complications were noted in all cases. FIL SSF lens is a good option for treating aphakia. This modified implantation technique is safe, fast, and easy. It is also versatile, combining the advantages of both previously described techniques, as it gives the option of flap conversion if needed. Larger studies and prospective comparative studies can highlight the best and more appropriate technique., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Batsos et al.)

Background: Non-traumatic ectopia lentis is a rare ocular disorder usually associated with syndromes like Marfans's syndrome, Weil-Marchesani and Homocystinuria. Ectopia lentis can lead to profound visual loss from refractive errors, glaucoma as well as retinal detachment if left unattended., Aim: The aim of this study was to describe the clinical profile of patients with non-traumatic ectopia lentis in a paediatric ophthalmology clinic in Ibadan, Nigeria., Methods: The clinical records of children ≤16 years diagnosed with non- traumatic ectopia lentis at the Paediatric Ophthalmology Clinic, University College Hospital Ibadan, from May 1, 2015 to Dec 31, 2019 were retrospectively reviewed. Information on demography, family history, visual acuity (VA), mean refractive error (spherical equivalent), and management was retrieved., Results: Clinical records of 25 patients were reviewed. The mean age was 8.9 (±3.41) years with a range of 2-15 years. Sixteen (64%) patients were males. All the patients had bilateral involvement. A positive family history of ectopia lentis was elicited in 6 (24%) patients. Thirteen (52%) patients had a Marfanoid habitus and superior displacement of the lens was observed in 26 (52%) eyes. The presenting visual acuity was <6/60 in 22 (44%) eyes. The spherical equivalent of the refractive errors ranged from -20.00DS to +13.25DS. Twenty (40%) eyes underwent surgery within the period of the study and the best corrected postoperative visual acuity improved by 2 or more lines in 12 (60%) of operated eyes., Conclusion: Severe visual morbidity was common in this cohort of patients with ectopia lentis in our practice. Treatment provided some improvement in vision which highlights the need to encourage early presentation for care. Detailed family history is important as a few of the patients were diagnosed following acceptance of our invitation to siblings for ophthalmic evaluation., Competing Interests: None to declare., (© Journal Name, Year.)

Introduction: After lens extraction, if the capsular bag insufficiency occurs, there are different IOL implantation techniques. IOL implantation in the posterior chamber is safer in eyes with low endothelial cell count, peripheral anterior synechiae, shallow anterior chamber, and glaucoma. Alternative approaches for scleral fixation techniques, both with and without sutures, continue to undergo development. In this study, we aimed to compare the postoperative outcomes of the sutured scleral fixation (SSF), haptic flanged intrascleral fixation (HFISF) and four flanged intrascleral fixation (FFISF) IOL implantation techniques in eyes with the absence of capsular support., Materials and Methods: A hundred and thirty-seven aphakic eyes with the absence of capsular support were included in the study. The patients were divided into three groups: group 1-SSF, group 2-HFISF (Yamane technique), and group 3-FFISF. Surgical time in minutes, preoperative and postoperative parameters such as best corrected visual acuity (BCVA), corneal astigmatism, lenticular astigmatism, intraocular pressure (IOP), specular microscopy, central macular thickness (CMT) were recorded. Pseudophacodonesis was assessed at 6 months postoperatively using a slit lamp, and early and late complications were recorded., Results: Of the 137 eyes, 69 eyes were included in the SSF group, 41 eyes in the HFISF group, and 27 eyes in the FFISF group. No statistically significant differences were observed among the three groups in terms of age, gender, preoperative mean BCVA, corneal astigmatism, IOP, endothelial cell density, and CMT. It was observed that the mean BCVA significantly improved compared to the preoperative visual acuity in all three groups. Postoperative lenticular astigmatism, pseudophacodonesis score, percentage of the endothelial cell loss were found to be higher in FFISF groups. The surgical time was found to be shorter in the HFISF group. IOL decentration was observed in 1.44% of the SSF group and 7.40% of the FFISF group. Cystoid macular edema was observed in 5.79% of the SSF group, 4.87% of the HFISF group, and 7.40% of the FFISF group. Retinal detachment was observed in 1.44% of the SSF group and 7.31% of the HFISF group., Conclusions: The optimal technique for treating aphakia without capsular support remains uncertain. Surgeons are tasked with a complex decision, aiming for both excellent vision and minimal risk. This decision is based on their expertise, the distinctive ocular condition of the patient, and the availability of essential operating room equipment. In this study, the following findings were observed: in the HFISF technique, the average surgical time was found to be shorter, the SSF technique demonstrated greater stability in terms of astigmatism and pseudophacodonesis and the FFISF technique was recognized for its relatively straightforward application method. It is important to note that the three IOL implantation techniques yielded comparable outcomes in terms of postoperative BCVA, as well as early and late complications., (© 2023.

Purpose: The study evaluates the rate of postoperative formation of a pupillary membrane (PM) and posterior visual axis opacification (PVAO) in infants with and without primary IOL implantation during the first 4 months of infancy., Methods: Medical records for 144 eyes (101 infants) operated between 2005 and 2014 were evaluated. A posterior capsulectomy and anterior vitrectomy were performed. Primary IOL implantation was performed in 68 eyes, while 76 eyes were left aphakic. There were 16 bilateral cases in the pseudophakic group and 27 in the aphakic group. The follow-up period was 54.3 ± 21.05 months and 49.1 ± 18.60 months, respectively. Fisher's exact test was used for statistical analysis. The two-sample t-test with equal variance was used to compare surgery age, follow-up period and time intervals of complications., Results: The mean age of surgery was 2.1 ± 0.85 months in the pseudophakic and 2.2 ± 1.01 months in the aphakic group. PM was diagnosed in 40% pseudophakic and 7% aphakic eyes. A second surgery for PVAO was performed in 72% pseudophakic and 16% aphakic eyes. Both were significantly higher in the pseudophakic group. In the pseudophakic group, the number of PVAO was significantly higher in infants operated before 8 weeks of age compared to surgery age 9-16 weeks. The frequency of PM was not age-dependent., Conclusion: Although it remains feasible to implant an IOL during the primary surgery, even in very young infants, there should always be solid arguments for this decision since it puts the child at higher risk of repeated surgeries under general anaesthesia., (© 2023.

Background: To comprehensively investigate risk factors for proliferative vitreoretinopathy (PVR) after retinal detachment (RD) surgery., Methods: PubMed, Embase, Cochrane Library, and Web of Science were systematically searched until May 22, 2023. Risk factors included demographic and disease-related risk factors. Odds ratios (ORs) and weighted mean differences (WMDs) were used as the effect sizes, and shown with 95% confidence intervals (CIs). Sensitivity analysis was conducted. The protocol was registered with PROSPERO (CRD42022378652)., Results: Twenty-two studies of 13,875 subjects were included in this systematic review and meta-analysis. Increased age was associated with a higher risk of postoperative PVR (pooled WMD = 3.98, 95%CI: 0.21, 7.75, P = 0.038). Smokers had a higher risk of postoperative PVR than non-smokers (pooled OR = 5.07, 95%CI: 2.21-11.61, P<0.001). Presence of preoperative PVR was associated with a greater risk of postoperative PVR (pooled OR = 22.28, 95%CI: 2.54, 195.31, P = 0.005). Presence of vitreous hemorrhage was associated with a greater risk of postoperative PVR (pooled OR = 4.12, 95%CI: 1.62, 10.50, P = 0.003). Individuals with aphakia or pseudophakia had an increased risk of postoperative PVR in contrast to those without (pooled OR = 1.41, 95%CI: 1.02, 1.95, P = 0.040). The risk of postoperative PVR was higher among patients with macula off versus those with macula on (pooled OR = 1.85, 95%CI: 1.24, 2.74, P = 0.002). Extent of RD in patients with postoperative PVR was larger than that in patients without (pooled WMD = 0.31, 95%CI: 0.02, 0.59, P = 0.036). Patients with postoperative PVR had longer duration of RD symptoms than those without (pooled WMD = 10.36, 95%CI: 2.29, 18.43, P = 0.012)., Conclusion: Age, smoking, preoperative PVR, vitreous hemorrhage, aphakia or pseudophakia, macula off, extent of RD, and duration of RD symptoms were risk factors for postoperative PVR in patients undergoing RD surgery, which may help better identify high-risk patients, and provide timely interventions., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Xiang et al.

Infantile cataract is one of the major causes of visual impairment in children. This article will discuss some of the techniques, challenges, complications, and compliance issues with aphakic contact lenses.

Aim: To identify the current surgical management of aphakia and the outcomes and complications of each technique., Methods: This cross-sectional study included ophthalmic surgeons with at least one-year experience in surgery for aphakia. A study questionnaire was formulated to collect data in Saudi Arabia and other regional countries. The questionnaire included 22 questions on demographics, preferred surgical techniques, complications and the factors related to surgeon decision and the choice for managing aphakia., Results: The study included 145 participants (111; 76.6% were males) with mean age of 46.7 ± 11.5 years. The mean duration of cataract surgery experience was 17.6 ± 11.1 years. Most participants (86.2%) were trained in cataract surgery. Scleral fixation of intraocular lens (SFIOL) was the most commonly preferred technique, followed by iris fixation IOL, and anterior chamber IOL (75.2%, 9%, and 15.9%, respectively). The main determinants for selection of a surgical technique were simplicity (56.6%), surgical instrument availability (48.3%), and training on the technique (47.6%). The most frequent postoperative complications were pupil distortion, high intraocular pressure (IOP), pupillary capture of the IOL, and IOL decentration., Conclusions: SFIOL is the preferred surgical technique for managing aphakia. The decision to choose one technique over another is complex and is based on several factors, including technical difficulty, previous training, anatomical variations, ocular comorbidities, and the potential complications. The most frequent complications after surgical correction of aphakia are pupil distortion, high IOP, pupillary capture of the IOL, and decentered IOLs., (© 2023.

Background: The main contact lens for pediatric aphakia has historically been a silicone elastomer lens (Silsoft SuperPlus). Due to supply chain disruption, many aphakic children required an alternative lens. We performed quantitative and qualitative comparisons between Silsoft SuperPlus and alternative aphakic soft contacts., Method: Sixty-nine aphakic eyes of 49 patients wearing Silsoft SuperPlus lenses underwent the refitting process into an alternative soft contact. Data collected included lens parameters, visual acuity, keratometry, horizontal visible iris diameter, and over-refraction. A 6-question survey assessing the patients'/guardians' experience with Silsoft SuperPlus versus the alternative lens was conducted at initial fit and 1-3 months post-fit., Results: Twenty-four patients (49 %), 4(8 %), and 1(2 %) were refit into Flexlens Definitive 74, Biofinity XR, and Intelliwave Pro Toric lenses, respectively. Sixteen patients (34 %) remained in Silsoft SuperPlus due to personal lens surplus or inability to handle the new lens while 2(4 %) opted for glasses. Silsoft SuperPlus was typically successful in eyes with average keratometry (AveK) 7.4-7.6 mm. Flexlens Definitive 74 required a base curve 0.4 mm steeper than the AveK. Patients'/guardias' reported a trend toward greater comfort with handling Silsoft SuperPlus, however, patients experienced less adverse side effects with the alternative soft contact lenses., Conclusions: Flexlens Definitive 74 was an adequate alternative to Silsoft SuperPlus in aphakic children, however lens parameters must be steepened. Keratometry streamlined the contact lens fitting process. Alternative soft lenses are a cost-effective alternative to Silsoft contact lenses., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Author(s).

Background: Pupil distortion and aphakia are common complications that follow blunt injury of the eye globe, surgical complications, and iris coloboma. Patients with these two complications complain of severe glare and photophobia even after successful intraocular lens (IOL) implantation like scleral fixation of intraocular lens (SFIOL) due to irregular pupil. To overcome this, we prefer to do pupilloplasty along with IOL implantation., Purpose: In this video, we demonstrate iris fixation of IOL using four-throw pupilloplasty; thus with one surgical technique, both pupilloplasty and iris fixation are done., Synopsis: The technique of an IOL implantation without capsular support can be challenging. There are different techniques, such as iris claw, iris fixation, and scleral fixation. Permanent mydriasis or distorted pupil can be a disabling condition, even after successful vision gain, due to photophobia. So pupilloplasty is nowadays preferred along with IOL implantation. Usually after IOL implantation, iris cerclage or pupilloplasty is done. We combined both steps with one technique: iris fixation with four-throw pupilloplasty. This technique can be used for iris coloboma with weak zonules and surgical iridectomy with aphakia cases where the pupil is irregular., Highlights: The video highlights the steps of four-throw pupilloplasty technique which is also used for fixating the IOL to the iris (iris fixation). This can give an excellent outcome in aphakia with distorted pupil using a single technique approach., Video Link: https://youtu.be/TEa54A5kg2I., Competing Interests: None

Purpose: To evaluate a new non-contact instrument (OA-2000) measuring the ocular biometry parameters of silicone oil (SO)-filled aphakic eyes, as compared with IOLMaster 700., Methods: Forty SO-filled aphakic eyes of 40 patients were enrolled in this cross-sectional clinical trial. The axial length (AL), central corneal thickness (CCT), keratometry ((flattest keratometry) Kf and (steep keratometry, 90° apart from Kf) Ks), and axis of the Kf (Ax1) were measured with OA-2000 and IOLMaster 700. The coefficient of variation (CoV) was calculated to assess the repeatability. The correlation was evaluated by the Pearson coefficient. Bland-Altman analysis and paired t test were used to analyze the agreements and differences of parameters measured by the two devices, respectively., Results: The mean AL obtained with the OA-2000 was 23.57 ± 0.93 mm (range: 21.50 to 25.68 mm), and that obtained with the IOLMaster 700 was 23.69 ± 0.94 mm (range: 21.85 to 25.86 mm), resulting in a mean offset of 0.124 ± 0.125 mm (p < 0.001). The mean offset of CCT measured by OA-2000 and IOLMaster 700 was 14.6 ± 7.5 μm (p < 0.001). However, the Kf, Ks and Ax1 values from the two devices were comparable (p > 0.05). All the measured parameters of the two devices showed strong linear correlations (all r ≥ 0.966). The Bland-Altman analysis showed a narrow 95% limits of agreement (LoA) of Kf, Ks and AL, but 95%LoA of CCT and Ax1 was wide, which were - 29.3 ~ 0.1 μm and-25.9 ~ 30.7°respectively. The CoVs of the biometric parameters obtained with OA-2000 were lower than 1%., Conclusion: In SO-filled aphakic eyes, the ocular parameters (including AL, Kf, Ks, Ax1, and CCT) measured by the OA-2000 and IOLMaster 700 had a good correlation. Two devices had an excellent agreement on ocular biometric measurements of Kf, Ks and AL. The OA-2000 provided excellent repeatability of ocular parameters in SO-filled aphakic eyes., (© 2023.

Background: Contact lenses play a substantial role in the management of childhood aphakia. However, the use and care of the lenses can be challenging. Despite its prevalence, the phenomenon of living with children with aphakia is not explained in Iran yet. The aim of this study was to illuminate the lived experience of the parents of children with aphakia., Materials and Methods: This hermeneutic phenomenological study was conducted on the parents who have been referred to Farabi Eye Hospital of Tehran, Iran in 2019, whose children were diagnosed with aphakia, and the condition was corrected with contact lenses. Qualitative semi-structured interviews were conducted with 20 parents of children with congenital cataract. Analysis was based on the framework of Diekelmann enabled data interpretation and elaboration of shared themes., Results: The 20 parents involved in the study consisted of 12 women and 8 men. The participant's experiences were classified in 4 categories: Self-Ignorance, Troubled mind, Self-Regulation, and Coping with the problem while hoping for the future., Conclusions: "Self-Ignorance" and "Troubled Mind" indicates that because of the risk of burnout in the long-term process of treatment, the psychological support of parents is necessary. Psychological support will continue until the parents acquire the ability of self-regulation. Giving a realistic hope to families is a core element in psychological support., Competing Interests: Nothing to declare., (Copyright: © 2023 Iranian Journal of Nursing and Midwifery Research.)

Purpose: To analyze visual outcomes and accuracy of intraocular lens (IOL) calculation formulas in predicting postoperative outcomes in patients undergoing flanged intrascleral IOL fixation., Design: Case Series., Subjects: Twenty-three patients who had undergone secondary IOL placement using flanged intrascleral fixation technique., Methods: Retrospective chart review., Main Outcome Measures: Corrected distance visual acuity (CDVA) and postoperative spherical equivalent based on manifest refraction., Results: Visual acuity improved from 20/577 to 20/58. Overall, the actual refraction was 0.06 D more myopic than predicted. Holladay 2, Sanders Retzlaff Kraff/Theoretical (SRK/T) and Barrett Universal II resulted in mild myopic surprise (-0.55, -0.18 and -0.20 D). Haigis and Hill-RBF (Radial Basis Function) resulted in mild hyperopic surprise (+0.28 and +0.28 D). Hoffer Q and Holladay 1 were the most accurate (-0.02D and -0.08 D)., Conclusion: Flanged intrascleral IOL fixation improved vision even in patients with other posterior segment pathologies. The effective lens positioning is likely similar to in-the-bag positioning. Hoffer Q and Holladay 1 formulas with in-the-bag calculations were the most accurate., Competing Interests: The authors report no conflicts of interest in this work., (© 2023 Malach et al.)

We describe gross and histopathological features of multiple ocular and neuro-ophthalmic abnormalities in a fox squirrel (Sciurus niger). Ophthalmic findings included severe bilateral microphthalmos, with the right eye more affected than the left. Histopathology confirmed severe microphthalmia, aphakia, disorganized retinal tissue and small optic nerves, as well as agenesis of the optic chiasm and optic tract. This combination of neuro-ophthalmic abnormalities has not been previously described in wild animals., Competing Interests: Declaration of competing interests The authors declared no conflicts of interest with respect to the research, authorship or publication of this article., (Published by Elsevier Ltd.)

Background: Scleral fixation of intraocular lens (IOLs) is the most preferred technique for the management of aphakia and the techniques have evolved over the years. These methods have their advantages and disadvantages, however, the major concern being the position of the intraocular lens, its stability and complications. The final IOL position is the major determinant of the final visual acuity, and various imaging modalities have been used to quantify the IOL tilt., Objectives: Use of Scheimpflug imaging to evaluate the IOL tilt in modified flanged scleral-fixated intraocular lens (MFSIOL)., Design: Retrospective chart review of 41 consecutive patients who underwent MFIOL., Methods: We conducted a retrospective chart review of 41 consecutive patients who underwent MFIOL. The baseline and final best-corrected visual acuity (BCVA), refractive error, and clinical examination findings were recorded. The vertical and horizontal tilts of the IOLs were calculated using the Scheimpflug image. The IOL tilt (in degrees) in the vertical and horizontal axes was the primary outcome and the BCVA, residual refractive error, intraocular pressure, and surgical complications were secondary outcome measures., Results: The mean baseline BCVA was logMAR 0.49, which improved to logMAR 0.356 ( p  < .005) after the surgery. The mean IOL tilt in the vertical axis was 3.40° (range of 0.0°-8.5°, interquartile range: 1.21-5.66) and in the horizontal axis was 1.35° (range of 0.60°-4.620°, interquartile range: 0.44-1.86), respectively. There was no correlation between angle of IOL tilt and UCVA ( r  = 0.089, p  = 0.580), BCVA ( r  = 0.109, p  = 0.498), final spherical error ( r  = 0.081, p  = 0.615), cylindrical error ( r  = 0.207, p  = 0.195), axial length ( r  = 0.105, p  = 0.514), and IOL power ( r  = -0.139, p  = 0.388)., Conclusion: Modified flanged IOL (MFIOL) is an alternative technique for intrascleral fixation of IOL resulting in good lens stability. The IOL tilt achieved by this technique is minimal and did not influence the final visual outcome or spectacle correction. Scheimpflug imaging is simple and non-invasive method to measure the IOL tilt., Plain Language Summary Scheimpflug Imaging for Modified Flanged Scleral Fixated Lens Position: This study on 41 eyes was aimed to analyze the lens tilt using Scheimpflug imaging in cases of modified flanged scleral fixation of intraocular lens (MFSFIOL), which is a novel technique to minimize the complications and simplify the procedure. The intraocular lens (IOL) remained stable with an acceptable range of vertical and horizontal tilt. There was no significant effect of IOL tilt on the final best-corrected visual acuity (BCVA) or spectacle correction. Scheimpflug imaging is an accurate and non-invasive technique for assessment of lens position in the patients with intrascleral fixation of IOL., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s), 2023.)

The aim of this multicenter, national clinical audit is to evaluate the predictive factors and management of postoperative macular edema (ME) after retropupillary iris-claw intraocular lens (RICI) implantation and pars plana vitrectomy (PPV). Preoperative, surgical and postoperative data were collected. Number and type of intravitreal injections (IT) administered (anti-VEGF or dexamethasone implant), visual acuity (VA), intraocular pressure (IOP) and central retinal thickness (CRT) assessed by OCT were collected at 1, 3, 6 and 12 months. From 325 eyes (325 patients), 11.7% (38/325) developed postoperative ME. Previous complicated cataract surgery with no capsular support was the only significant predictive factor for developing postoperative ME (OR 2.27, 95% CI 1.38-4.52, p = 0.02) after RICI implant. Mean time to ME development was 11.4 ± 10.7 weeks, and mean CRT peaked at 3 months follow-up. Different treatment options were non-steroidal anti-inflammatory (NSAIDs) drops (31.6%, 12/38), dexamethasone (DEX) implant (50%, 19/38), anti-VEGF (7.9%, 3/38) or combined IT (10.5%, 4/38). Cumulative probability of ME resolution was higher in the group treated with IT than in the group treated with topical NSAIDs (85.2% vs. 58.3%, p = 0.9). Performing RICI implantation after complicated cataract surgery is a risk factor for the development of postoperative ME. DEX implants may be an effective treatment for postoperative ME in these cases.

This commentary describes steps in ocular reconstruction surgery following ocular globe injuries in both the anterior and posterior segment causing corneal opacity and aphakia. The authors propose to reorder the sequence of surgical manoeuvres during pars plana vitrectomy combined with keratoplasty and aphakia treatment without capsular support and highlight the advantages in the choice of the intraocular lens to implant. A mental outline of all surgical manoeuvres, being aware of the complications that can arise during surgery and knowing the long-term benefits of making more careful choices, can make this surgery more effective and safer., (© 2022.

Purpose: To determine the relative contribution of intraocular lens (IOL) calculation accuracy and ocular growth variability to the long-term refractive error predicted following pediatric cataract surgery., Methods: Pseudophakic eyes of children enrolled in the Infant Aphakia Treatment Study (IATS) were included in this study. Initial absolute prediction error (APE) and 10-year APE were calculated using the initial biometry, IOL parameters, postoperative refractions, and mean rate of refractive growth. The cohort was divided into children with a low-initial APE (≤1.0 D) and a high-initial APE ( >1.0 D). The 10-year APE was compared between the two groups using the Mann-Whitney U test. Linear regression was used to estimate the variability in prediction error explained by the initial IOL calculation accuracy., Results: Forty-two children with IOL placement in infancy were included. Seventeen eyes had a low initial APE, and 25 eyes had a high initial APE. There was no significant difference in APE 10 years following surgery between individuals with a low initial APE (median, 2.67 D; IQR, 1.61-4.12 D) and a high initial APE (median, 3.45 D; IQR, 1.64-5.10 D) (P = 0.7). Initial prediction error could explain 12% of the variability in the prediction error 10 years following surgery., Conclusions: IOL calculation accuracy contributed minimally to the refractive error predicted 10 years after cataract surgery in the setting of high variability in the rate of refractive growth., (Copyright © 2022 American Association for Pediatric Ophthalmology and Strabismus.

Purpose: To assess the incidence of glaucoma after combined Descemet's stripping endothelial keratoplasty (DSEK) and retropupillary fixated iris-claw intraocular lens (IOL) implantation in the patients with bullous keratopathy (BK) who required secondary IOL or IOL exchange., Methods: In this retrospective case series, medical records of 22 patients who underwent combined DSEK and retropupillary fixated iris-claw IOL implantation were evaluated. Preoperative vision, intraocular pressure (IOP), postoperative IOP at different time periods, and intraoperative and postoperative complications were analyzed., Results: A total of 22 eyes of 22 patients (7 females and 15 males) were analyzed. The median age was 62 years, and the median duration of the postoperative follow-up was 106.5 days. The corrected distance visual acuity improved from a median of 1.85 logMAR to 1.68 logMAR. None of the patients had intraoperative complications. Three patients (13.6%) had dislocation of the donor tissue on the 1 st postoperative day and were successfully rebubbled. Six eyes (27.3%) had graft failure and required penetrating keratoplasty. Eleven eyes (50%) had a sustained rise in the IOP, of which 2 (9.09%) had ocular hypertension and 9 eyes (40.9%) progressed to glaucoma., Conclusions: DSEK combined with retropupillary fixated iris-claw lens is a good surgical option for the management of aphakic/pseudophakic BK in patients who require secondary IOL or IOL exchange. Regular IOP monitoring after the surgery is an essential, as there is a risk of IOP rise and glaucoma in the postoperative period. Clinicians should be vigilant and control the IOP to prevent glaucoma progression., Competing Interests: There are no conflicts of interest., (Copyright: © 2022 Journal of Current Ophthalmology.)

Purpose: To compare the efficacy and safety of conventional scleral fixation (C-SF), retropupillary iris-claw intraocular lens (RP-IOL) implantation, and intrascleral fixation (ISF)., Methods: This retrospective observational study included 58 patients (58 eyes) who underwent C-SF (23 eyes), RP-IOL (23 eyes), and ISF (12 eyes) by a single surgeon at Samsung Medical Center from October 2017 to July 2020 and were followed up for at least 6 months. This study analyzed various clinical outcomes before surgery, and 1 day, 1 week, 1 month, 3 months, and 6 months after surgery., Results: Six months after surgery, best-corrected visual acuity in logarithm of minimum angle of resolution was 0.08 ± 0.10, 0.08 ± 0.16, and 0.03 ± 0.04 in C-SF group, RP-IOL group, and ISF group, respectively, and there was a significant improvement in each group compared to preoperative best-corrected visual acuity. All groups showed a significant increase in astigmatism postoperatively, but no between-group differences were observed. The prediction error was -0.15 ± 0.77, 0.56 ± 0.62, and 0.44 ± 1.00 diopters in the three groups, respectively, indicating RP-IOL group and ISF group for hyperopic shift. The three groups did not differ in terms of absolute prediction error. Six months after surgery, the corneal endothelial cell counts were 2,073 ± 691, 2,014 ± 692, and 1,712 ± 891 cells/mm2, respectively, which were lower than before surgery. IOL dislocation occurred in five eyes only in RP-IOL group, two of which underwent two reoperations, and reenclavation was performed smoothly without complications in all cases., Conclusions: Although the frequency of IOL dislocation in RP-IOL group was higher than that in the other groups, it can be reenclavated relatively easily. As a method of secondary IOL fixation, both RP-IOL implantation and ISF were as effective as conventional scleral fixation.
