Abstract
En 中文
Keratoprosthesis (KPro) implantation serves as a last resort for visual rehabilitation in patients with end-stage bilateral corneal blindness, particularly when conventional corneal transplantation is no longer viable. Advances in biomaterials and refinements in prosthetic design have significantly enhanced anatomical retention and visual outcomes. Among the various types available, the Boston type 1 and 2 devices and the modified osteo-odonto-KPro remain the most widely utilized globally. This review aims to support comprehensive clinical decisionmaking by providing an in-depth overview of the design characteristics, surgical considerations, and postoperative care protocols associated with the most widely used KPro devices. In addition, we discuss a broad range of influencing factors, including the status of the ocular surface, eyelid anatomy, tear film adequacy, underlying systemic or autoimmune diseases, is placed on the importance of preoperative evaluation and counselling and the role of a multidisciplinary approach in achieving successful longpropose a practical decision-making algorithm to aid ophthalmologists in selecting the most appropriate KPro tailored to individual patient profiles.
