<unk>  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<unk>  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.  They vary in design, size and even the implantation techniques may differ across different treatment centers. The procedure is done by ophthalmologists, often on an outpatient basis.
