If the corneal stroma has developed opaque patches known as leukomas, a cornea of a deceased donor can be transplanted. Because there are few blood vessels in the cornea, there are also few problems with rejection of the new cornea.

There are also synthetic corneas in development. Most are merely plastic inserts, but there are also some made of plastics that encourage the eye tissue to grow into the synthetic cornea making it a full replacement.

Non-surgical procedures involving the cornea

Orthokeratology is a method using specialized hard or rigid gas permeable contact lenses to reshape the cornea in order to improve the refractive state of the eye or reduce the need for eyeglasses and contact lenses.
