Abstract
Purpose
The aim of the present study was to compare the results of Descemet's stripping automated endothelial keratoplasty (DSAEK) and ultrathin Descemet's stripping automated endothelial keratoplasty (UT-DSAEK) that were performed with a standardized technique at a single institution.
Design
The present study was designed as a single-center, prospective, randomized nonblinded study.
Participants and methods
Sixty-one and 51 eyes underwent DSAEK and UT-DSAEK, respectively, for any endothelial disease at the ‘Villa Igea’ Center. Patients with pre-existing ocular comorbidity that impacted visual potential such as macular degeneration, amblyopia, advanced glaucoma, and other optic neuropathies were excluded from the study.
Main outcome measures
Visual acuity improvement, ECL, intraoperative postoperative complications, iatrogenic primary graft failure, and rebubbling were the main outcome measures in this study.
Results
Mean ± SD BCVA improved from 0.17 ± 0.13 and 0.19 ± 0.13 before surgery to 0.75 ± 0.18 and 0.88 ± 0.19 at 1 year after DSAEK and UT-DSAEK, respectively ( = 0.001). ECL was 33.88 ± 17.74% after DSAEK and 36.37 ± 13.10% after UT-DSAEK ( = 0.4080). There were no iatrogenic primary graft failures after the two procedures but there were two late endothelial failures after DSAEK. Rebubbling was performed for four of 51 eyes after UT-DSAEK and for none after DSAEK ( = 0.04).
Conclusion
Compared with DSAEK, UT-DSAEK provided better visual recovery and comparable ECL. The UT-DSAEK group had a higher percentage of rebubbling procedures but less rejection and failure rate.
