Corneal Transplantation for Keratoconus

Abstract

Penetrating grafts performed for keratoconus exhibited better visual outcome and graft survival than grafts performed for other indications. However, the Kaplan-Meier survival rate of first penetrating grafts for keratoconus was 17% at 23 years after graft and had not plateaued at this time, indicating that young patients are likely to need 1 or more repeated grafts during their lifetime.
