The fate of the graft after extracorneal keratoplasty.

Two histological examinations are described. The first presents a full-thickness graft after extracorneal keratoplasty 2 years after transplantation. The graft is localized in the host tissue, externally lined by the thickened episclera and internally by the sclera. The reaction of the host tissue is slight and the graft is well preserved. In the second, a lamellar graft, rare capillaries grow 1 year after transplantation, the reaction of the host tissue is very mild, and the graft slowly changes into the original tissue of the host.
