LASIK (laser in-situ keratomileusis) is a popular surgery to correct nearsighted and farsighted eyes as well as astigmatism.
LASIK works by reshaping the cornea with a laser, which allows light to be focused onto the retina. A laser is used to create a small flap is in the cornea, which is removed, allowing another laser can reshape the cornea. The flap is then returned to its original position, and the surgery is complete.
LASIK is quite popular because it has a high success rate. The procedure itself is quick, taking only a few minutes and most patients require only local anesthetics, which is given in eye-drop form.
In some cases, PRK (photo refractive keratectomy) is a better surgical option. There isn’t a flap created in PRK, rather the eye surgeon removed the outer layer of the cornea to expose an area for the laser to treat. The same laser is used to treat the cornea in both PRK and LASIK surgery.
Every surgery has risks, so it is important to discuss the surgery, side effects, and recovery with your eye doctor so you can make an informed decision about whether or not the procedure is right for you.
