To compare the outcomes in eyes with Fuchs endothelial corneal dystrophy after standard phacoemulsification with those of femtosecond laser–assisted cataract surgery. Bascom Palmer Eye Institute, Miami, Florida, USA. Retrospective case series. Charts from patients diagnosed with Fuchs endothelial corneal dystrophy who had phacoemulsification cataract surgery at Bascom Palmer Eye Institute between January 1, 2014, and January 1, 2017, were reviewed. The Institutional Review Board, University of Miami Human Subjects Research Office, approved the study protocol. Complicated surgeries and cases with concurrent keratoplasty, previous keratoplasty or glaucoma surgery, or a follow-up shorter than 3 months were excluded. The corrected distance visual acuity (CDVA), central corneal thickness (CCT), and corneal edema at each visit were analyzed. Clinically significant corneal decompensation was defined by corneal edema with CDVA worse than 20/50 lasting more than 3 months, any case resulting in keratoplasty, or both. The study comprised 207 eyes of 207 patients (64 femtosecond laser–assisted cataract surgery, 143 conventional phacoemulsification). Demographics, baseline guttata and cataract grades, and follow-up time (mean 30 months) were similar between groups (P > .05). The proportion of cases progressing to clinically significant decompensation (13%) was similar between groups (P > .05). Univariate Cox survival analysis also found no difference (hazard ratio, 1.0; 95% confidence interval, 0.4-2.7; P = .96). Compared with conventional phacoemulsification, femtosecond laser–assisted cataract surgery did not lower the rate of corneal decompensation in eyes with mild to moderate Fuchs endothelial corneal dystrophy.
