Aim: To enquire whether patients with dry eye symptoms also report dry skin, whether their perception could be corroborated with objective measurement, and whether dry eye disease might be suspected based on patients' complaints., Methods: This cross-sectional study included 50 subjects, 25 with and 25 without dry eye symptoms. Schein questionnaire was used to determine the severity of dry eye symptoms. Ocular signs were assessed by monitoring conjunctival hyperemia, ocular surface staining, meibomian gland expression, tear film lipid layer thickness, tear break-up time, lid parallel conjunctival folds, Schirmer test, and meibometry. Skin dryness was assessed by noting patients' self-perception of their facial skin dryness and measured by sebumeter., Results: Subjects without dry eye symptoms had self-reported oilier facial skin than those with dry eye symptoms (p < .001). Sebumetry scores measured on the forehead and cheek were significantly higher in subjects without dry eye symptoms than dry eye subjects (p = .003). After adjustment for age and gender in a logistic regression analysis, dry eye was independently and significantly associated with dry skin (AOR 0.69, p = .040), higher LIPCOF score of both eyes (AOR 2.28, p = .028), lower sebumetry score of the forehead (AOR 0.98, p = .041) and cheek (AOR 0.98, p = .041), and shorter TBUT score after gland expression (AOR 0.90, p = .018)., Conclusion: This study showed that ocular dryness was subjectively and objectively positively correlated to facial skin dryness. Patients reliably described their skin condition. People with dry facial skin also had drier eyes.

Background: The most common complications after performing the triple Descemet's stripping automated endothelial keratoplasty (DSAEK), which combines the cataract phacoemulsification, intraocular lens implantation and DSAEK procedure, are detachment or decentration of the donor lamella and postoperative interface haze. One reason for this is the retained viscoelastic used during surgery., Objective: This study aimed to describe triple DSAEK procedure without the usage of viscoelastic and to discuss its potential benefits on surgical outcomes., Methods: The surgical procedures and outcomes of patients with Fuchs' dystrophy and lens opacification who underwent the triple DSAEK were retrospectively reviewed. The surgical procedure was described, and postoperative complications were studied., Results: The study included 10 eyes of 10 patients. Capsulorhexis and IOL implantation performed in locally potentiated anesthesia compared to general anesthesia did not significantly differ (P > 0,05). The mean preoperative best-corrected visual acuity was 0.75 LogMar. The mean postoperative best-corrected visual acuity was 0.2 LogMar. The central graft thickness before surgery was 129.6 μm and 6 months after surgery was 114.2 μm. Successful attachment of the donor lamellae was observed in all 10 patients. None of the patients had postoperative interface haze or any other possible viscoelastic caused complication., Conclusion: Although viscoelastic can facilitate certain aspects of the triple DSAEK procedure, we conclude that this procedure can be performed completely without its use. If performed by a trained surgeon, the procedure can be feasible without the complications of donor lamella detachment, decentration, or interface haze., Competing Interests: The authors have no conflicts of interest to disclose., (© 2023 Tomislav Kuzman, Ana Pupic-Bakrac, Ana Meter, Ivana Gabric, Dina Lesin Gacina, Sania Vidas Pauk, Andjela Jukic, Ivan Skegro, Sanja Masnec, Miro Kalauz.)

Purpose : To determine the feasibility of non-invasive tear break-up time (NIBUT) assessment using the Handheld tear lipid layer thickness assessment instrument and compare it with the standard tear break-up time (TBUT) test and other dry eye tests. Subjects and methods : 108 subjects were enrolled, 56 with and 52 without dry eye symptoms. Schein questionnaire was used to determine the severity of dry eye symptoms. Ocular signs were assessed by NIBUT, TBUT, lipid layer thickness (LLT), lid-parallel conjunctival folds (LIPCOF), conjunctival hyperemia, and corneal staining. Results : Median NIBUT and TBUT, and other clinical test values significantly differed among the dry eye symptoms group and control group. NIBUT yielded the most significant difference between the groups (NIBUT: 7 sec vs. 17.5 sec, p < .001, Z = 5.94; TBUT: 5 sec vs. 10 sec, p < .001, Z = 4.38; LLT: p = .007; LIPCOF: p < .001, conjunctival hyperemia: p < .047, corneal staining: p < .010). Spearman's test showed a significant correlation between NIBUT and TBUT ( p < .001), NIBUT and LLT ( p = .001), NIBUT and LIPCOF ( p = .019), NIBUT and conjunctival hyperemia ( p = .002), and NIBUT and corneal staining ( p = .012) in the dry eye symptoms group. NIBUT did not significantly differ among the three measurements in both groups of patients ( p = .061, p = .096), while TBUT values did in the control group ( p < .001). Short NIBUT values were the main predictors and indicators of dry eye complaints (AOR = 0.87, p < .001), superior to TBUT (AOR = 0.88, p = .008) and other tests even after adjustment for age and gender. Conclusion : NIBUT measured by Handheld instrument is a simple, accessible, practical, and, most of all, reproducible and objective method that might allow NIBUT assessment on a regular basis.
