is the clear covering of the front of the eye. It bends (or refracts) light rays as they enter the eye. For clear vision to occur, the cornea must have the correct shape. It must also have the power to focus incoming light rays precisely on the retina. If the cornea is too steep, too flat or irregular in shape, it cannot bend light at the angle needed to focus on the retina. As a result, eyeglasses or contact lenses may be needed to correct this. In a nearsighted eye, for example, the cornea’s shape causes incoming light rays to focus in front of the retina.
All corneal modification procedures are intended to alter the curvature of the cornea. It will allow incoming light refracted at an angle that allows it to focus precisely on the retina. This may eliminate the need for eyeglasses or contact lenses, or reduce the power of prescription lenses needed.
Those interested in any of the corneal modifications should first have a comprehensive eye examination to evaluate their eye health and determine their vision needs.
