A keratoprosthesis is a medical device designed to serve as a synthetic replacement for the cornea, which is the transparent front part of the eye. This procedure is typically indicated in cases where a human donor corneal transplant has failed or when the likelihood of success for a donor transplant is low. The keratoprosthesis itself is made from a clear plastic material that mimics the natural cornea's transparency and curvature. During the procedure, the synthetic graft is carefully sutured into human donor tissue, which is then attached to the patient's existing damaged cornea. This complex surgical intervention aims to restore vision in patients who have severe corneal damage or disease. After the keratoprosthesis is securely positioned and sutured in place, a soft contact lens is applied over the eye. This lens is crucial as it must be worn continuously, 24 hours a day, to protect the eye and support the healing process following the surgery.
