Penetrating keratoplasty after placement of a temporary keratoprosthesis during pars plana vitrectomy.

Five eyes of five patients with opaque corneas underwent penetrating keratoplasty after pars plana vitrectomy. In each case, the Landers-Foulks temporary keratoprosthesis provided visualization of the vitreous cavity and retina, allowed successful removal of hemorrhagic vitreous, and permitted retinal reattachment. Corneal grafts remained clear in two eyes; three grafts developed stromal edema. Useful postoperative vision was achieved in two eyes. However, proliferative vitreoretinopathy, postoperative hypotony, atrophia bulbi, and corneal edema resulted in poor vision in three eyes.
