Before you could begin with the surgery, try understanding issues like the vision types that could be corrected by LASIK surgery. People who wear contact lens or glass are affected by refractive error. This refractive error is of four types which include hyperopia, presbyopia, astigmatism and myopia. A person is called “emmetropic” if he/she has perfect eye sight and still lacks refractive error.

The light rays are allowed to enter along the cornea and it focuses on the retina directly at the back of the eye in the case of refractive error. Myopic eye are the type in which the cornea steeps and so the light rays focus in front of retina and this causes blurry effect of the distant object. The cornea doesn’t steep and so the light rays are focused behind the retina in the hyperopic eye.

When it comes to astigmatism, the cornea is irregular in shape and scatters light rays and this causes blurred effect to both distant and closer objects. In Presbyopia, the lens loses its elasticity. Because of this the affected person loses his/her ability to read at close distance. Here reading glasses are recommended for these patients and it has corrective lenses. People with perfect vision might develop presbyopia at the age of forty and above.
