Laser Refractive Surgery
The cornea is the clear covering on the front of the eye which bends, or refracts, light rays that focus on the retina in the back of the eye. A certain corneal curvature is required for light to focus exactly on the retina and produce a clear image. The corneal curvature can be surgically changed through refractive surgery procedures such as LASIK, PRK, LASEK, INTACS, and AK (astigmatic keratotomy also called LRI or limbal relaxing incisions). Refractive lensectomy or clear lens extraction utilizes an intraocular lens implant to change the refractive error of the eye. Refractive surgeries improve vision and reduce or eliminate the need for eyeglasses or contact lenses. A thorough eye examination and consultation are necessary before a treatment decision can be made.
