LASIK surgery is a type of eye surgery that permanently alters 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 for eyeglasses or contact lenses. The procedure is performed with a laser programmed to remove a defined amount of tissue from the cornea. In eyes with normal vision, the cornea refracts light precisely onto the retina at the back of the eye.
Before undergoing LASIK surgery, doctors often use wavefront-guided technology to evaluate the eye in detail. Most people who have had this procedure will have good to excellent vision in most situations for many years or decades. There are certain terms and issues to consider, practices to follow, and questions to ask your doctor before undergoing LASIK surgery.The eye surgeon uses a small blade or a sharp laser to cut a small, hinged flap to separate it from the front of the eye. Laser eye surgery is best suited for people who have a moderate degree of refractive error and who don't have unusual vision problems.
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. For people with presbyopia, LASIK cannot correct vision so that one eye can see both up close and far.Your eye doctor will talk with you about whether LASIK surgery or another similar refractive procedure is an option that works for you. Before a LASIK procedure, the eye doctor will evaluate detailed eye measurements and evaluate the overall health of the eye. It will take two to three months after surgery before the eye heals and vision stabilizes.
LASIK eyesurgery is one of the most popular laser refractive surgeries used to correct vision problems.
During this procedure, an eye surgeon creates a flap in the cornea (A), which is the transparent dome-shaped surface of the eye that represents a large part of the eye's bending or refractive power. Certain health conditions can increase the risks associated with LASIK surgery or make the outcome less predictable.LASIK is an effective way to improve vision and reduce dependence on eyeglasses or contact lenses. However, it is important to understand all aspects of this procedure before making a decision about whether it is right for you. Talk with your doctor about any questions or concerns you may have about LASIK surgery.
