Keratomileusis
Keratomileusis
Keratomileusis (pronunciation: ker·a·to·mi·leu·sis) is a type of refractive surgery used to correct myopia, hyperopia, and astigmatism. The term is derived from the Greek words "kerato," meaning cornea, and "mileusis," meaning carving.
History
Keratomileusis was first developed by Spanish ophthalmologist José Ignacio Barraquer in 1949 in his clinic in Bogotá, Colombia. The procedure was later modified and popularized as LASIK (Laser-Assisted In Situ Keratomileusis) in the 1990s.
Procedure
In keratomileusis, a microkeratome, a precise surgical instrument, is used to create a thin flap in the cornea. The cornea is then reshaped using a laser, which removes a small amount of corneal tissue. The flap is then repositioned on the reshaped cornea. The procedure is typically performed under local anesthesia.
Risks and Complications
As with any surgical procedure, keratomileusis carries potential risks and complications. These may include infection, dry eyes, glare, halos, and starbursts. In rare cases, complications can lead to loss of vision.
