Keratoprosthesis

Abstract

Keratoprosthesis (KPro), also known as the "artificial cornea, " can be considered as an alternative in cases where standard corneal transplant has failed or has a very low probability of success. These cases include repeat graft failure, severe neovascularization, and limbal stem cell deficiency. There are numerous types of KPro available today. The most commonly used device worldwide is the Boston KPro Type 1, but in those with severe ocular surface keratinization and eyelid dysfunction, the Boston KPro Type 2, modified osteo-odonto-KPro, and tibial bone KPro are good options. Proper preoperative evaluation and postoperative care are critical for the success of KPro. The preoperative diagnosis is a significant determining factor of keratoprosthesis success. Patients with KPro are at risk of complications throughout the lifetime of their device, including infection, retroprosthetic membrane, and glaucoma. Despite this, KPro has been able to restore vision and change the lives of many blind individuals.
