Objective: To identify baseline (donor, recipient, operative) factors that affect endothelial cell loss following penetrating keratoplasty for a moderate-risk condition (principally Fuchs’ dystrophy or pseudophakic/aphakic corneal edema). Methods: In a subset (n=567) of Cornea Donor Study (CDS) participants, preoperative and postoperative endothelial cell density (ECD) were determined by a central reading center. Multivariate regression analyses were performed to examine which baseline factors correlated with ECD over time. Results: Larger grafts (p<0.001), younger donor age (p < 0.001) and female donor gender (p = 0.004) were significantly associated with higher ECD during follow up. Mean endothelial cell loss at 5 years was 68% for > 8 – 9 mm grafts, 75% for 7 - < 8 mm grafts and 74% for those grafts 8.0mm in diameter. Grafts from female donors experienced a 67% cell loss compared with a 72% cell loss among grafts from male donors. Method of tissue retrieval, donor cause of death, history of diabetes, and time from death to preservation or to surgery were not significantly associated with changes in ECD over time (n=567). Conclusions: Following penetrating keratoplasty for endothelial dysfunction conditions, larger donor graft size, younger donor age and female donor gender were associated with higher ECD over five years. This data warrants exploring the possibility that similar associations may exist following endothelial keratoplasty.
