Keratoprosthesis is a surgical procedure where a severely damaged or diseased cornea is replaced with an artificial cornea. While conventional cornea transplant uses donor tissue for transplant, an artificial cornea is used in the Keratoprosthesis procedure. The surgery is performed to restore vision in patients suffering from severely damaged cornea due to congenital birth defects, infections, injuries and burns. Keratoprotheses are made of clear plastic with excellent tissue tolerance and optical properties. Indications of keratoprotheses include the following: Treatment of patients whose vision are less than 20/400 in the affected eye, Patients with failed corneal transplant using donor cornea and have little or no vision left, Patients with non-autoimmune diseases, congenital birth defects and other ocular problems. The primary purpose of Keratoprosthesis is to improve vision in patients with complex ocular diseases who are at high risk for donor graft failure. After an impressive success record with Keratoprosthesis in adults, the procedure is used to treat young patients with severe ocular deformities. An artificial cornea or Keratoprosthesis has great potential to benefit millions worldwide who are blind due to corneal disease. the patient meets the ophthalmologist for eye examination and other tests weeks or months preceding surgery. During the meeting, the ophthalmologist will examine the eye and diagnose its condition. The doctor will also record the history of the patient’s health and other previous eye treatments, if any. The doctor will discuss the risks and benefits of the surgery. If the patient elects for the surgery, the doctor will have the patient sign an informed consent form.
