Laser vision correction surgery is for anyone who has impaired vision due to common refractive errors such as

Myopia (nearsightedness) - In a nearsighted eye the shape of the cornea is too steep or the eye is too long. As a result, visual image cannot be focused directly on the retina and the "picture" transmitted to the brain is blurred.

Hyperopia (farsightedness) - In a farsighted eye either the shape of the cornea is too flat or the eye is too short. The visual image comes to a focus behind the retina and the "picture" transmitted to the brain is blurred.

Astigmatism - The shape of an astigmatic eye is more like an egg than the basketball shape of a normal eye. This irregular shape causes light rays to come to a focus at more than one point in the eye. As a result the images seen by an astigmatic person are often blurred and distorted.
