We reviewed 47 eyes in 39 cases who underwent penetrating keratoplasty during 8 years through 1998. Following factors affecting graft rejection were analyzed using the life-table theory and multivariate analysis : sex, age, causative disease, postoperative vascularization, preoperative complications, surgical method, systemic corticosteroid, topical cyclosporine, postoperative intraocular pressure (IOP) , and sutural failure. The survival rate without immunological rejection by the Kaplan-Meier method was 74.1% at 1 year and 58.4% at 3 years of surgery. Statistical evaluation by Cox proportional hazard model and logistic model showed the immunological rejection to be significantly affected by postoperative complications, corneal vascularization and, in particular, postoperative IOP elevation. Quantitation study type II identified sutural failure and postoperative complications as factors involved in occurrence of immunological rejection.
