Abstract

Corneal transplantation, also known as keratoplasty, is a surgical procedure in which a damaged or diseased cornea is replaced with a healthy cornea from a donor. This procedure is performed to restore vision in patients who have suffered corneal damage due to various reasons such as infection, injury, or degenerative diseases. The cornea is the transparent outermost layer of the eye that covers the iris and the pupil. It functions as a protective barrier against environmental factors and helps in focusing light onto the retina. Corneal disease or damage can result in reduced vision, and in severe cases, blindness.
