Results of penetrating keratoplasty carried out in our department in 152 eyes (including 141 eyes undergoing allograft keratoplasty and 11 eyes undergoing autograft keratoplasty) were evaluated and more over the causes of graft failure were analyzed in eyes that underwent allograft keratoplasty. The overall transparency rate was 74% at 1 year after operation and 65% at the final assessment period (40.8 months later on average). Postoperatively, visual acuity was improved in 76% of cases. The transparency rate varied significantly according to the presence or absence of pre- or postoperative vascularization and anterior synechia, severity of corneal opacification, the presence or absence of allograft reaction and glaucoma. Graft rejection, anterior synechia and glaucoma were significantly involved in graft failure. The cumulative transparency rate varied according to various factors. These results, indicated that the prognosis of the graft is greatly influenced by conditions of the host cornea and the appearance of postoperative complications.
