Lasik eye surgery is a surgical procedure that can correct a person’s vision. When an individual has Lasik surgery they will no longer have to depend on glasses or contact lenses.

The cornea of the eye is responsible for projecting light onto the retina to produce an image. When the cornea of the eye is not shaped perfectly, then the image will be distorted. This is called a refractive error. Lasik eye surgery can correct a refractive error.

There are three primary types of refractive errors. Myopia is a refractive error in which a person has trouble seeing things at a distance but they can see things close up. Hyperopia is when a person will be able to see things clearly at a distance but cannot see things that are close to them. Astigmatism is a distortion of an image that is caused by irregularities in the cornea or lens of the eye.

Lasik eye surgery is also called refractive surgery because it will reshape the shape of the cornea, therefore improving the focusing power. But keep in mind that not everyone is a good candidate for Lasik eye surgery.
