AI Article Synopsis

  • The study compares DSAEK and DMEK outcomes performed by a skilled surgeon, focusing on patients with Fuchs corneal dystrophy.
  • This retrospective analysis involved 200 eyes across 132 patients and tracked postoperative complications and visual acuity, revealing that while DMEK offered better vision at six months, it also showed higher endothelial cell loss and complications like posterior synechiae.
  • Overall, transitioning from DSAEK to DMEK can lead to excellent visual outcomes with minimal complications, emphasizing the importance of following standardized surgical techniques.

Article Abstract

Purpose: To compare outcomes of Descemet stripping automated endothelial keratoplasty (DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) when an experienced DSAEK surgeon transitions to DMEK while following 2 published endothelial keratoplasty surgical techniques.

Methods: This is a retrospective review of 200 eyes of 132 patients with Fuchs corneal dystrophy that underwent endothelial keratoplasty performed by one surgeon. Published, standardized techniques were followed for both DSAEK and DMEK. Postoperative complications were recorded. Best spectacle-corrected visual acuity (BSCVA), intraocular pressure, and central endothelial cell loss (ECL) were evaluated at 6 months postoperatively.

Results: There were no intraoperative complications. One DSAEK and 5 DMEK grafts developed graft detachment requiring rebubbling (P = 0.097). No iatrogenic primary graft failures occurred in the DSAEK group compared with one in the DMEK group. No pupil block episodes occurred in the DSAEK group compared with one in the DMEK group. Posterior synechiae formation occurred 15 times in the DMEK group and did not occur in the DSAEK group (P < 0.001). At 6 months, BSCVA was better in the DMEK group than in the DSAEK group (20/24; logMAR = 0.0844-20/32; logMAR = 0.2063) (P < 0.001). More eyes reached 20/20 or better BSCVA in the DMEK group compared with DSAEK (54.5%-13%) (P < 0.011). At 6 months, ECL was higher in the DMEK group than in the DSAEK group (31.9%-19.9%) (P < 0.001).

Conclusions: Complications can be minimized and excellent outcomes can be achieved, without a steep learning curve, when an experienced DSAEK surgeon transitions to DMEK following a standardized technique. Six-month vision outcomes are better in the DMEK group; however, the rate of a newly described complication, posterior synechiae formation, and 6-month ECL are higher in the DMEK group than in the DSAEK group.

Purpose: To evaluate Descemet membrane endothelial keratoplasty (DMEK) for failed endothelial keratoplasty (EK).

Methods: We reviewed 362 consecutive DMEK cases for failed EK (Descemet stripping endothelial keratoplasty (DSEK) or DMEK), 118 for early EK failure, and 244 for late failure in 333 eyes of 323 patients without penetrating keratoplasty. Rejection and graft survival rates were assessed with Kaplan-Meier analysis.

Purpose: To identify areas of consensus among experts on the performance of endothelial keratoplasty by using a modified Delphi approach, to help create a framework for novice surgeons to adopt these procedures.

Methods: Thirty-one international experts in endothelial keratoplasty participated. Two rounds of electronic survey were followed by a hybrid, virtual meeting.

Purpose: The postoperative occurrence of corneal guttae (CG) in patients after Descemet membrane endothelial keratoplasty (DMEK) can lead to a significant reduction in visual acuity (VA) with the subsequent need for repeat DMEK. Therefore, the aim of this study was to analyze the prevalence and clinical significance of CG in transplanted corneas after DMEK.

Methods: The prevalence and progression of CG after DMEK of 1657 patients were examined using endothelial specular microscopy images.

Introduction: To evaluate the anterior chamber (AC) inflammation in the early postoperative period after cataract surgery and before Descemet membrane endothelial keratoplasty (DMEK) by quantifying oxidative stress and inflammatory mediators in aqueous humor of patients with Fuchs' endothelial corneal dystrophy (FECD).

Methods: In this prospective single-center study, 15 patients with FECD underwent cataract surgery and DMEK in a two-stage procedure. Aqueous humor was collected from the AC at the beginning of cataract surgery and 3 months later at the beginning of DMEK.

Article Synopsis
  • The study aimed to analyze how a surgeon's learning and experience affect the outcomes of endothelial keratoplasty (EK) procedures over time.
  • It examined a large dataset of EK transplants (over 11,500) performed between 2005 and 2020, focusing on factors such as surgeon experience and the timing of new EK techniques.
  • The findings showed that surgeon experience significantly impacted transplant success rates and complications, highlighting the importance of training and support systems to improve surgical outcomes over time.*
