What Are Corneal Transplants And What They Do?
Corneal transplants are also known by another name and that is corneal grafting. It is a surgical procedure that is done on the human eye. What this surgical procedure entails is this. It mainly involves surgery done to the cornea of the eye that is damaged or diseased. The damaged or diseased cornea is removed and is replaced with donated corneal tissue that is called the graft. If the entire cornea of the eye is replaced, it is called penetrating keratoplasty, and if only a portion of the cornea is replaced it is known as being lamellar keratoplasty. The word keratoplasty only refers to the surgery to the cornea that is performed. The graft that is used to replace the damaged or diseased cornea is taken from someone who has recently died and had no known diseases or other factors that may affect the chances of survival of the donated tissue or the health of the recipient of it in any way.
