Vitreoretinal aspects of permanent keratoprosthesis.

Overview

Permanent keratoprosthesis (KPro) is a treatment option in patients with severe corneal disease not amenable to traditional penetrating keratoplasty. There are several types of permanent keratoprostheses available for use worldwide, including the Boston KPro, osteo-odonto KPro, and AlphaCor, among others. A multidisciplinary team of cornea, glaucoma, and vitreoretinal specialists is necessary to ensure proper patient selection, preoperative planning, keratoprosthesis placement, postoperative monitoring and management of complications. We provide a comprehensive review of the vitreoretinal aspects of permanent keratoprostheses.
