Abstract:
Visualizing the posterior segment during vitreoretinal surgery can be difficult in eyes with concurrent corneal opacity. Temporary keratoprostheses have emerged as devices that ensure visibility of the posterior vitreous cavity while simultaneously preserving the donor corneal graft. Several models of these devices are described in the current literature, and new design models and surgical techniques surrounding their use continue to be developed. We summarize the different temporary keratoprosthesis models with their associated surgical techniques, advantages, and shortcomings; discuss the clinical results of studies utilizing these devices; and examine alternative tools and techniques for approaching combined anterior and posterior segment operations.
