[Problems in perforating keratoplasty with large diameter].

The follow-up of 52 perforating corneal grafts with a diameter of more than 9 mm is presented. The indications for surgery in this series were different from those in a control group. In the 3-year follow-up time most transplants were clear and had a good final visual outcome. Secondary glaucomas were not significant, but a high endothelial cell density decrease could be demonstrated.
