Graft Thickness After Penetrating Keratoplasty

Graft thickness was studied in 70 patients subjected to penetrating keratoplasty. A postoperative swelling was followed by a decreasing thickness during 3–4 months, after which period the graft was found to be thinner than normal, and in cases with a normal contralateral eye, thinner than the cornea of that eye. During the following months the graft thickness increased and finally assumed the value of the contralateral cornea. Any complications during the postoperative course were immediately reflected in an increased thickness. Quantitative data supporting the above statements are given, treated statistically when adequate.
