Abstract

The Corneal Transplant Follow-up Study has followed 2311 penetrating keratoplasties for up to 450 days after transplant. A total of 207 failures were observed, including 65 classical rejections and 35 endothelial decompensations. At 12 months, graft survival was 89%, and survival free from rejection was 87%. For surviving grafts, risk of failure reduced from 4.8% in the first 75 days and stabilized after 5 months at 1.2% in each 75-day interval. Risk of rejection initially followed a similar pattern, but then increased after 12 months. Multifactorial analyses accounted for differences in recipient characteristics and interrelationships of donor factors. Donor age, sex, cause of death, and method of corneal storage were not found to influence significantly either time to graft failure or time to first rejection. Grafts in prospectively tissue-typed donor-recipient pairs were generally considered before surgery to be at increased risk of either graft failure or rejection. With due allowance, increasing risk of rejection was associated with increasing numbers of mismatches at HLA-A and HLA-B broad antigens. The opposite was true at HLA-DR broad antigens, where increased risk of rejection was observed with no mismatches.
