The procedure known as refractive surgery is utilized to correct the refractive defect (spectacle power) in the eye. Usually, the goal is to reduce or completely do away with the need for contact lenses and glasses. It can be completed once the patient is between the ages of 18 and 21 and has a constant refraction (glass power). A complete medical history and an extensive examination of the eyes, including corneal topography (Pentacam, Orbscan), anterior segment optical coherence tomography (ASOCT), and other tests, are required of all candidates. These tests are performed to evaluate the cornea’s thickness, curvature, and other characteristics. After compiling all the data, the ophthalmologist (eye surgeon) determines the patient’s refractive surgery options.
