Outcomes after Descemet membrane endothelial keratoplasty over a period of 7 years at a tertiary referral center: endothelial cell density, central corneal thickness, and visual acuity

Abstract

Purpose: To better assess clinical trajectories of patients with or without ocular comorbidity after Descemet membrane endothelial keratoplasty. Background: To report on the outcomes of eyes with differing starting conditions following surgery. Design: Retrospective study at a University Eye Hospital. Participants: 361 eyes separated into group 1 (n=229; eyes with endothelial disease only) and group 2 (n=132; eyes with additional ocular comorbid conditions, such as herpetic eye disease 18/132 (13.6%), glaucoma 16/132 (12.1%), dry age-related macular degeneration 14/132 (10.6%), epiretinal membranes 10/132 (7.6%), and wet age-related macular degeneration 9/132 (6.8%)). Methods: Consecutive eyes that underwent Descemet membrane endothelial keratoplasty over a follow-up period of up to 7 years at a tertiary referral center were reviewed. Main outcome measures were best-corrected visual acuity, postoperative complications, graft survival, central corneal thickness, and endothelial cell density. Results: Postoperative best-corrected visual acuity at year 1 improved in both groups significantly (Wilcoxon signed rank test: group 1, p =.002;.63 to.23 logMAR; group 2, p
