Laser Intrastromal Keratomileusis (LASIK) is a type of refractive eye surgery used to correct common vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. This procedure utilizes a laser to reshape the cornea, the transparent front part of the eye, effectively improving the way light is focused onto the retina to enhance visual acuity.
During LASIK surgery, a microkeratome or femtosecond laser creates a thin hinged flap on the cornea, which is then lifted to expose the underlying corneal tissue. The laser is then used to precisely remove a predetermined amount of tissue from the stromal layer, which lies beneath the cornea's surface. The goal is to reshape the cornea, altering its curvature to correct the refractive error causing the vision problem. The flap is then repositioned back onto the cornea and left to naturally adhere without requiring stitches or bandages.
LASIK is considered a safe and effective treatment option for individuals with stable vision and suitable corneal thickness. The procedure is typically completed within minutes, with minimal discomfort experienced by the patient. After LASIK, visual recovery is usually rapid, and many individuals achieve improved vision within a few days or weeks. However, as with any surgical procedure, there are potential risks and side effects, such as dry eyes, visual disturbances, and temporary discomfort.
Overall, LASIK has become a popular choice for individuals seeking long-term vision correction without the need for glasses or contact lenses, providing them with the opportunity to achieve clearer, sharper vision.
