title: [Old versus young donor corneas].
abstract: Postoperative thinning curves of 52 corneal grafts in keratoconus eyes show no significant difference between young and old donor material during the first 8 days. There is also no significant difference in the surgical and further postoperative endothelial cell loss up to 2 years. The examination of 23 grafts performed 17 years ago revealed an average cell density of 860 per mm2-independent of the donor age. The clinical experience that graft clarity is not related to the donor age and our present findings suggest that there is no upper age limit for corneal donor material.
