To compare keratometry data between the handheld Retinomax K-plus 3 and the table-mounted IOLMaster 700. Healthy adult volunteers were prospectively recruited to the study. All participants underwent 3 consecutive keratometry measurements using the Retinomax K-plus 3 and a single biometry assessment using the IOLMaster 700. Differences between the Retinomax K-plus 3 and the IOLMaster 700 were assessed using Wilcoxon test for paired samples, Spearman correlation, Bland–Altman and mountain plots. Twenty-eight healthy subjects with a median age of 37 years (interquartile range (IQR) 28–44 years) were included in the study. The median mean keratometry (mean K) reading was higher using the Retinomax K-plus 3 (44.04D; IQR 42.96–45.61D) compared to the IOLMaster 700 (43.78D; IQR 43.22–44.90D, p

Mean K readings were highly correlated between the 2 devices (r = 0.995, p 0.01). Bland-Altman plots showed 95% limits of agreement between -0.14D and 0.49D. Frequency histogram of mean K reading differences between the Retinomax K-plus 3 and the IOLMaster 700 showed that 56% of cases were between ± 0.2D, 93% of cases were between ± 0.4D and all cases were between ± 0.5D. Mean corneal astigmatism measurement was higher using the Retinomax K-plus 3 (1.01 ± 0.40D) compared to the IOLMaster 700 (0.77 ± 0.36D), with a mean difference of 0.23 ± 0.37D (p 0.01) between the devices.A good agreement exists between the Retinomax K-plus 3 and the IOLMaster 700 regarding keratometry readings. This enables cataract surgeons to safely use the Retinomax K-plus 3 device when indicated.

The aim of the study was to examine the outcomes of transepithelial photorefractive keratectomy (Trans-PRK) and Femtosecond Laser-assisted in situ keratomileusis (Z-LASIK) for the correction of high myopia. A retrospective cohort study design was used. The study group included 792 eyes with high-grade myopia (− 6.0 diopters or higher) or high-grade myopia with astigmatism that were treated with Z-LASIK or Trans-PRK in 2013 through 2014 in an optical outpatient clinic of a large private medical service. The Trans-PRK group comprised of 674 eyes with a spherical equivalent (SE) of − 7.87 ± 1.46 and the Z-LASIK group comprised of 118 eyes with a SE of − 7.19 ± 0.81 (P

Corneal melting with perforation is a severe ophthalmic complication of autoimmune disorders such as rheumatoid arthritis. It requires urgent medical management in order to maintain the integrity of the globe and preserve vision. Treating this complication by penetrating keratoplasty is problematic due to the high rate of recurrence of corneal melting as well as other complications. We describe the use of a tectonic fresh-tissue corneolimbal covering graft. An interventional case series including three patients that presented to our tertiary center between 2000 and 2015 with corneal melting and perforation, secondary to rheumatoid arthritis. Emergency surgery included suturing of a 13.00- to 13.50-mm full-thickness fresh-tissue corneolimbal covering graft to the patient’s posterior limbal zone. The corneolimbal graft maintained the integrity of the cornea in all cases, by sealing the perforation and promoting the creation of a fibrovascular scar at the area of corneal melting. There were no complications, recurrences of host corneal melting, or perforation during the follow-up period. Fresh-tissue full-thickness corneolimbal grafts may be used to cover emergency corneal melting and perforations secondary to rheumatoid arthritis.
