Our eyes are a natural camera. Light enters the eye through the following channels: cornea, eyewater, lens and the vitreous body, which then focuses it onto the retina. The cells in the retina then carry the light signals to a specific location in the brain where they are interpreted.

The curved shape of the cornea plays an important role in the function of the eye. It greatly effects certain types of vision dysfunctions and is the ideal place to perform vision correction procedures.

Laser procedure increases or decreases the arch of the cornea; it is made either flatter or more convex to focus the light correctly into the retina, as it would with a healthy eye.
