Keratoplasty, also known as corneal transplantation, is a surgical procedure that involves replacing a damaged or diseased cornea with a healthy cornea from a donor. The cornea is the transparent, dome-shaped surface that covers the front of the eye and plays a crucial role in focusing light into the eye.
Keratoplasty can be used to treat a variety of conditions, including corneal scarring, thinning, clouding and swelling, as well as some forms of corneal dystrophy and degeneration. The procedure can also be used to correct certain refractive errors, such as astigmatism.
