LASIK is a laser vision correction procedure used to treat common refractive errors such as nearsightedness, farsightedness, and astigmatism. The procedure reshapes the cornea so that light entering the eye is properly focused on the retina, resulting in clearer vision and reduced dependence on glasses or contact lenses. Before LASIK is recommended, patients undergo a comprehensive eye evaluation that includes vision testing, corneal mapping, and measurements of corneal thickness and eye health. These tests help determine whether LASIK is a safe and effective option and allow the surgeon to customize the treatment plan to the patient’s visual needs. During the procedure, a thin corneal flap is created and gently lifted. An advanced laser is then used to precisely reshape the underlying corneal tissue. The flap is repositioned without stitches, allowing it to heal naturally. The procedure is painless, typically takes only a few minutes per eye, and is performed under topical anesthesia. Most patients notice improved vision within 24 hours, with minimal downtime. LASIK has a long track record of safety and effectiveness and is one of the most commonly performed elective eye procedures worldwide.
