keratomileusis
Pronunciation: /ˌkɛrətoʊmaɪˈluːsɪs/
Surgical reshaping of the cornea by removing and remodeling stromal tissue to correct refractive errors.
Full Definition
Keratomileusis encompasses surgical techniques that reshape the cornea's curvature by selectively removing or remodeling stromal tissue to correct myopia, hyperopia, and astigmatism. Modern keratomileusis procedures include LASIK, PRK, and SMILE, which use excimer laser technology to precisely ablate corneal tissue according to computer-calculated treatment patterns. The term derives from Greek words meaning 'cornea' and 'carving,' reflecting the fundamental principle of corneal sculpture for vision correction.
Usage
Usage note: Broader term encompassing multiple laser vision correction techniques; specify the exact procedure when possible.
