LASIK surgery is performed with a laser programmed to remove a defined amount of tissue from a part of the eye called the cornea. LASIK is eye surgery that permanently changes the shape of the cornea (the transparent covering of the front of the eye). It is done to improve vision and reduce a person's need to wear eyeglasses or contact lenses. Certain health conditions can increase the risks associated with LASIK surgery or make the outcome less predictable.
Most people who undergo LASIK surgery will have good to excellent vision in most situations, for many years or decades. Doctors often use wavefront-guided technology to evaluate the eye in detail before LASIK surgery. Certain medical conditions, not related to the eyes, can increase the risks associated with LASIK surgery or make the outcome less predictable. LASIK (laser-assisted in-situ keratomileusis) is the most common type of refractive eye surgery to correct vision problems.
Your eye doctor will talk with you about whether LASIK surgery or another similar refractive procedure is an option that works for you. LASIK eye surgery can treat a variety of vision problems, such as myopia (myopia), farsightedness (farsightedness), and astigmatism (irregularly shaped surface of the eye). If you're tired of wearing eyeglasses or contact lenses, you may be wondering if LASIK surgery is right for you. The long-term results of LASIK are often better in people who are carefully evaluated before surgery to ensure that they are good candidates for the procedure.
There is a glossary of terms and a list of issues to consider, practices to follow, and questions to ask your doctor before undergoing LASIK surgery. More than 8 out of 10 people who have undergone LASIK refractive surgery no longer need to wear eyeglasses or contact lenses for most of their activities.
