Keratotomy
Keratotomy (pronounced: ker-uh-TOT-uh-mee) is a surgical procedure involving the incision of the cornea, the clear front surface of the eye. The term is derived from the Greek words "kerato," meaning cornea, and "tomy," meaning cutting.
Etymology
The term "Keratotomy" is derived from the Greek words "keras" (κέρας) meaning "horn" and "tome" (τομή) meaning "cutting". The term was first used in the medical field to describe a surgical procedure involving the incision of the cornea.
Procedure
Keratotomy is performed to correct refractive errors in the eye, such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The most common type of keratotomy is Radial Keratotomy (RK), where radial incisions are made in the cornea to flatten it and correct myopia. Another type is Astigmatic Keratotomy (AK), which involves making incisions in the cornea to correct astigmatism.
Risks and Complications
Like any surgical procedure, keratotomy carries some risks. These may include infection, corneal edema, corneal scarring, and changes in the shape of the cornea that can lead to vision problems. It is important to discuss these risks with a healthcare provider before deciding to undergo this procedure.
