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
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 <.001; 1.15 to .87 logMAR) with a group difference in favor of group 1 (p =.009, Mann-Whitney-Wilcoxon). A decrease of the endothelial cell density and central corneal thickness was noted at postoperative year 1 for both groups (paired t-tests (group 1, p <.001; group 2, p =.045) and paired t-tests (group 1, p <.001; group 2, p =.003). Complications were less common, and graft longevity was superior in group 1. Conclusion Eyes with different starting conditions might experience a visual improvement and benefit from surgery. Descemet membrane endothelial keratoplasty is a valid treatment for endothelial disorders in manifold of eyes. Further long-term studies are required..
