Definition keratoplasty (corneal graft)

keratoplasty (corneal graft)

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 be replaced (penetrating keratoplasty) or only some of it's layers, the deeper layer remaining (lamellar keratoplasty). In the latter case the thickest of the replacement cornea is correspondingly reduced.
