Corneal grafts performed on 398 recipient eyes with at least six months follow up and adequate donor information were evaluated to determine the relationship of donor age to success in penetrating keratoplasty. Graft results, classified as clear, nebulous, or edematous, were compared in each of four donor age groups within three prognostic categories. No statistically significant difference in results due to donor age could be demonstrated.
