Graft failure in keratoepithelioplasty.

We report three patients undergoing keratoepithelioplasty using donor limbal tissue. All three had significant vascularization of the recipient bed and all three had inflammatory reactions with apparent partial replacement of the donor epithelium with host epithelium. Limbal transplantation, which is likely to include significant numbers of donor Langerhans' cells, may well increase the risk of graft failure in keratoepithelioplasty.
