What is keratoplasty?

Keratoplasty is a surgical procedure that involves the transplantation of corneal tissue to restore vision or improve the health of the cornea. It is commonly performed to treat conditions such as corneal scarring, keratoconus, or corneal thinning. The procedure can involve either a full-thickness transplant (penetrating keratoplasty) or a partial-thickness transplant (lamellar keratoplasty), depending on the specific condition being treated. Keratoplasty aims to replace damaged or diseased corneal tissue with healthy donor tissue.
