A surgical procedure involving the removal or partial removal of the cornea (the clear front part of the eye), sometimes performed to correct vision problems.
From Greek κέρας (keras, horn/cornea) + -ektomia (removal/excision), both ancient medical Greek roots used for describing surgical procedures.
Ceratectomy is one of the ancestors of modern LASIK eye surgery—surgeons realized they could reshape the cornea to fix vision, leading to today's precise laser vision correction.
