Does LASIK correct nearsightedness (myopia)?

LASIK is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.

Myopia is the medical term for “nearsightedness”.  Being nearsighted means you can see near objects well without the use of glasses or contact lenses, but your distance vision is blurry.  Myopia affects about one out of every 3 or 4 people.

In order to correct nearsightedness with LASIK, the steep parts of the cornea, which cause the refractive error are flattened using cool pulses of ultraviolet light emitted by the laser, thus allowing light to focus directly on the retina in the back of the eye.
