Keratoplasty was performed on 3482 eyes from 1965 to 1986 in our hospital. Five eyes (0.14%) were infected in the early postoperative period. Two eyes had endophthalmitis. These seven eyes were operated on again and with local and systemic antibiotics treated as well. Followed up for 36 days to 7 years, six eyes remained safe (5 eyes transparent and 1 eye semi-transparent.) The visual acuity reached 0.3 in two eyes, 0.2 in one eye and finger counting to 0.1 in three eyes. The seventh eye was enucleated because of serious infection. Several factors of infection in the early postoperative period following keratoplasty, causative organisms, the relations between the types of operation in the early postoperative period following keratoplasty were also discussed.
