Refractive surgery is a type of eye surgery aimed at correcting vision problems, such as nearsightedness, farsightedness, and astigmatism. The most common procedures include LASIK and PRK, which reshape the cornea to improve how light is focused on the retina. This can reduce or eliminate the need for glasses or contact lenses. The surgery typically involves using a laser to alter the cornea's curvature. Most patients experience quick recovery times and improved vision shortly after the procedure. However, like any surgery, there are potential risks and side effects, so it's important to consult with an eye care professional before proceeding.
