The endothelium of 36 clear penetrating keratoplasties, performed 1 to 19 years previously, was examined and photographed with the clinical specular microscope. There were fewer central endothelial cells in the transplants than in normal corneas. There was no significant correlation between graft endothelial cell density and corneal thickness, rejection episodes, the disease necessitating kertoplasty, or the method of donor tissue preservation. Corneas transplanted from younger donors to younger recipients had significantly more central endothelial cells...

A computer analysis of 87 penetrating kertoplasties done in a uniform manner by a single surgeon revealed the following: 1. On a statistical basis small grafts (7.0 mm) provided better visual acuity than larger grafts (8.0 mm). 2. On a statistical basis small grafts will be clearer postoperatively than larger grafts. 3. On a statistical basis the age of the donor is not related to either graft clarity or visual acuity.

A description is given of two patients who had a severe wound dehiscence with traumatic aphakia after perforating kertoplasty. In both cases, after vitrectomy and resuturing the transplant remained clear in its central part (visuel accuity 0.7 p). Details of the operative technic are discussed.

The most common causes of acquired corneal scarring before age 6 are herpes simplex keratitis, penetrating injuries, and congenital dystrophies. We performed 18 keratoplasties in 16 eyes of 15 patients under the age of 12 years, achieving clear grafts in 14 eyes (87%). We also performed 11 grafts in nine eyes of eight patients with congenital, central corneal opacities, achieving only one clear graft and four instances of phthisis bulbi or enucleation for buphthalmos. We do not recommend penetrating keratoplasty in patients with unilateral, congenital corneal opacities...
