Temporary Keratoprosthesis for Combined Penetrating Keratoplasty, Pars Plana Vitrectomy, and Repair of Retinal Detachment

Abstract The Landers-Foulks temporary keratoprosthesis was used to combine penetrating keratoplasty, pars plana vitrectomy, and scleral buckling in the management of 13 eyes with opaque cornea and posterior segment abnormalities. In seven cases, trauma precipitated the ocular disease. Complications of cataract surgery resulted in anterior and posterior segment pathology in six cases. The corneal graft was initially clear in all cases. However, corneal edema complicated phthisis bulbi in four cases and followed homograft reaction in two cases. Eight eyes with retinal detachment (RD) preoperatively were successfully reattached. In five eyes, the retina redetached as these eyes became phthisical. Visual function improved in six cases. In general, eyes with a history of trauma had a much poorer outcome than did eyes with anterior and posterior segment problems related to previous cataract surgery.
