Vision Correction Surgery

The cornea is the clear covering at the front of the eye. It bends the light rays as they enter and fall on the retina at the back of the eye. The bending process is also known as refraction.

The cornea needs to have the correct shape and power to focus the incoming light rays exactly on the retina at the back of the eye. Only in this way can correct vision occur. Sometimes a cornea is flat or irregular in shape and cannot adequately bend the light rays to focus on the retina. When this happens, eyeglasses or contact lenses may be needed to refract the light rays accurately on the retina so that clear vision occurs. For example, in the condition known as myopia or short-sightedness, the incoming light rays fall in front of the retina and cause distorted vision.

There are various corneal modification procedures available to alter the curvature of the cornea so that incoming light is properly focused on the retina to produce good vision. These procedures can eliminate the need for eyeglasses or contact lenses, or possibly reduce the power of prescription lenses should they still be necessary.

If you are interested in corneal modifications it is important to first have a comprehensive eye examination to evaluate your eye health and vision needs.
