If you suffer from nearsightedness, farsightedness or astigmatism, you likely have a refractive eye error that causes light that passes through your cornea to bend, or refract, improperly, resulting in your vision problem. Fortunately, you might be an appropriate candidate for refractive surgery to improve or correct your vision.
One of the best-known refractive surgical procedures is LASIK (laser-assisted in situ keratomileusis), which involves the use of laser energy to reshape the cornea (the clear, round dome at the front of your eye), thereby correcting your refractive error. In addition to LASIK, there are several other types of refractive surgery that can be performed to improve or correct the following vision problems:
- Nearsightedness (myopia). For those with myopia, close objects look clear, but distant objects are blurry.
- Farsightedness (hyperopia). For patients with hyperopia, distant objects look sufficiently clear, but close objects are blurry.
- Astigmatism. With astigmatism, the cornea or lens is not smooth or evenly curved, so the eyes do not focus properly.
- Presbyopia. This is an age-related eye condition that makes it harder to see images or objects up close.

Myopia, or nearsightedness, means that your eyes can see close objects clearly but struggle to see things in the distance. Nearly 30 percent of Americans are nearsighted.
This condition usually develops in children and teenagers, up to about the age of 20. A teacher or parent might notice a child squinting
