LASIK, or "laser-assisted in situ keratomileusis" is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision.
In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results — improved vision without eyeglasses or contact lenses — can usually be seen in as little as 24 hours.
A number of vision correction surgeries are available, such as PRK and LASEK laser eye surgery and phakic IOL surgery.
Your eye doctor will determine if laser eye surgery is suitable for your condition and, if so, which technique is best.
