Purpose: To compare 5-year graft survival after Descemet stripping automated endothelial keratoplasty (DSAEK) and penetrating keratoplasty (PK) in Asian eyes., Design: Prospective, nested, cohort study., Participants: Consecutive patients who underwent DSAEK (423 eyes) or PK (405 eyes) for Fuchs' endothelial dystrophy (FED) or bullous keratopathy (BK)., Methods: Clinical data and donor and recipient characteristics were recorded from our prospective cohort from the Singapore Corneal Transplant Registry. All surgeries were performed by the corneal surgeons at our center, which included cases performed or partially performed by corneal fellows in training under direct supervision., Main Outcome Measures: Five-year cumulative graft survival., Results: Overall mean age was 67.8±9.8 years, and 50.1% of patients were men. There were no significant differences in age (P = 0.261) or gender (P = 0.78) between PK and DSAEK groups in our predominantly Chinese (76.6%) Asian cohort, with more BK compared with FED (68.1% vs. 31.9%; P < 0.001). Overall 5-year graft survival was superior for DSAEK compared with PK (79.4% vs. 66.5%; P < 0.001, log-rank test). Median 5-year percent endothelial cell density loss was significantly greater in PK compared with DSAEK (60.9% vs. 48.7%; P = 0.007). Cox regression analysis revealed that BK was a significant factor associated with graft failure (hazard ratio [HR], 3.30; 95% confidence interval [CI], 2.05-5.33; P < 0.001), and PK was more likely to fail compared with endothelial keratoplasty (HR, 1.61; 95% CI, 1.08-2.41; P = 0.02) adjusting for confounders such as recipient age, gender, and donor factors. Five-year cumulative incidence of complications such as graft rejection (P < 0.001), epitheliopathy (P < 0.001), suture-related corneal infections (P < 0.001), and wound dehiscence (P = 0.002) were greater in the PK group compared with the DSAEK group., Conclusions: In Asian eyes from the same study cohort with standardized surgical and postoperative regimes, 5-year graft survival was superior for DSAEK compared with PK in eyes with FED and BK., (Copyright © 2016 American Academy of Ophthalmology.

Purpose: To describe the demographics, presenting symptoms, indications for surgery, and surgical outcomes of epiblepharon correction in a tertiary care hospital in Singapore., Design: Retrospective review of patients who underwent surgery by 2 surgeons in a referral oculoplastic practice at the National University Health System, Singapore, from 2001 to 2007., Participants: A total of 108 patients who underwent surgery for clinically significant epiblepharon., Intervention: Modified Hotz procedure or suture correction for patients in whom conservative treatment failed., Main Outcome Measures: Comparison of symptoms, keratopathy, and recurrence on follow-up between the 2 procedures., Results: The mean age of the patients was 9.0 years, with an age range of 0.5 to 68 years. Of the patients, 51.9% were male. The majority were Chinese (n = 102). Seventy-four (68.5%) patients were symptomatic. Eighty-nine patients (82.4%) had keratopathy. In 98 patients (90.7%) both eyes were affected, and the majority of patients (75.0%) had epiblepharon of the lower lids. Initial treatment for the majority was lubricants (n = 71, 65.7%). The main indications for surgery were symptoms and keratopathy, with 37.9% of patients having both, and 44.4% and 15.7% of patients having either keratopathy or symptoms alone, respectively. Surgical correction consisted mostly of a modified Hotz procedure (n = 88, 81.5%), lid-everting sutures (n = 9, 8.3%), and others, including upper lid blepharoplasty with lid crease formation (n = 11, 10.2%). Outcomes were good, with the majority (n = 88, 81.5%) of lids being well corrected. Complications included undercorrection, overcorrection, wound dehiscence, and wound infections., Conclusions: Symptomatic epiblepharon, usually associated with keratopathy and commonly seen in children of East Asian descent, often requires surgical intervention with good surgical outcome. Increased awareness among ophthalmologists and pediatricians dealing with this ethnic group and age is emphasized. Contrary to the current practice of expectant observation, definitive surgical management should be considered when symptoms or keratopathy is present., Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article., (Copyright 2010 American Academy of Ophthalmology.
