an operation involving corneal grafting.

It is performed when there are persistent opacities (leukomas) of the cornea that cause a severe decrease in vision, in order to partially or completely restore vision. Sometimes keratoplasty is resorted to also for cosmetic reasons. In keratoplasty the altered cornea is excised and in its place a disk of similar shape and size is grafted that is taken from the cornea of a person whose eye was removed for other reasons.
