The cornea is the clear tissue in front of the eye that covers the colored iris and pupil and is often referred to as the “window” of the eye. The cornea helps direct light towards the lens for focusing and allows light to pass through it to reach the back of the eye. For clear vision, the cornea must be healthy and clear. Because the cornea is the outermost part of the eye, several factors can disrupt corneal health including injury and corneal disease. These factors can prevent light from passing through the cornea, thus affecting vision.
Although it appears that the cornea is one distinct membrane, it is actually composed of five different layers. Each layer has a distinct function with the outermost layer serving as a protective shield to harmful factors. The smoothness and shape of the cornea is as vitally important to its proper functioning as is its transparency. If either the surface smoothness or the clarity of the cornea is disturbed, vision becomes distorted.
Various refractive eye surgery techniques change the shape of the cornea in order to reduce the need for corrective lenses or otherwise improve the refractive state of the eye.
