keratoplasty

keratoplasty
= corneal graft; n.
an eye operation in which any diseased parts of the cornea are replaced by clear corneal tissue from a donor. All layers of the cornea may need to be replaced (penetrating keratoplasty) or only the superficial layers, the deeper layer remaining (lamellar keratoplasty). In the latter case the thickness of the replacement cornea is correspondingly reduced. Lamellar keratoplasty has the advantage over penetrating keratoplasty of not requiring the eye to be opened, and therefore the risk of infection is greatly reduced.
