Gender Matching Did Not Affect 2-year Rejection or Failure Rates Following DSAEK for Fuchs Endothelial Corneal Dystrophy

Abstract

To investigate whether donor to recipient gender or H-Y mismatching was associated with graft rejection or failure following Descemet stripping automated endothelial keratoplasty (DSAEK) in patients with Fuchs endothelial corneal dystrophy (FECD). Clinical cohort study. This study used a multi-center registry including patients aged >18 years who had undergone their first DSAEK for FECD between January 2008 and March 2018. The impact of donor and recipient gender incompatibility (including H-Y mismatches) on corneal graft rejection and failure was evaluated using Kaplan-Meier curves and univariable and multivariable Cox models. Outcome data from 4341 eyes (3915 from the UK and 426 from Italy) were analyzed. Graft failure at 2-year follow-up occurred in 477 (11.0%) cases. Graft rejection at 2-year follow-up occurred in 175 cases (4.0%), 58 (1.3%) of whom developed graft failure. There was no significant effect of gender or H-Y mismatching on either rejection (P=.12, P=.06) or failure (P=.28, P=.14), respectively. In patients with FECD undergoing DSAEK, no significant influence of gender and or H-Y mismatch on graft rejection or failure was found.
