[Changes in the endothelial cell density after perforating keratoplasty].

Abstract

We examined 590 endothelial photomicrographs of 327 patients with computerized morphometry; these patients had undergone penetrating keratoplasty in the period from 1981 to 1987. We found a weak negative correlation of r = -0.39 between postoperative endothelial cell density and the postoperative period. The endothelial cell density in the interval 12-24 months postoperatively averaged 1624 cells/mm. This is approximately 380 cells/mm more than described in other studies of that kind. We found significantly higher cell densities for cultured corneas and for corneas of young donors (age up to 39 years) up to 1 year postoperatively. Comparison of the diagnosis groups showed no relevant differences in postoperative cell density.
