Coretomy is a medical term referring to the surgical procedure of removing or excising a part or all of the cornea, which is the transparent front surface of the eye. This procedure is often performed to correct various ocular disorders that affect vision. The word "coretomy" is derived from the Greek word "kóris," meaning pupil, and "tómē," meaning incision or cutting.
During a coretomy, an ophthalmologist makes a precise incision in the cornea using specialized surgical instruments. The purpose of the procedure may vary depending on the specific condition being treated. For instance, it can be employed to remove scars or opacities from the cornea, which may obstruct vision. Additionally, coretomy can be utilized to reshape the cornea, altering its curvature to correct refractive errors like astigmatism, myopia (nearsightedness), or hyperopia (farsightedness).
Coretomy may be performed using traditional surgical techniques or advanced technologies such as lasers. Laser-assisted coretomy, also known as refractive corneal surgery, involves the use of laser beams to precisely reshape the cornea, providing more predictable and controlled outcomes.
Like any surgical procedure, coretomy carries risks, including infection, bleeding, or corneal damage. Therefore, it is typically conducted by highly skilled and experienced ophthalmic surgeons in specialized surgical settings. A comprehensive preoperative evaluation, including an assessment of the patient's overall eye health, is crucial to determine the suitability for coretomy. Postoperative care, including the use of topical medications and regular follow-up appointments, is essential to ensure optimal healing and visual outcomes.
