Our LASEK procedure uses no blades and is performed on the surface of the cornea to make sure our patients have the safest laser vision correction available. This technology offers hope for improved sight with less dependence on corrective eye-wear. LASEK is performed with an excimer laser, which uses a light beam to precisely ablate very tiny bits of tissue from the surface of the cornea in order to reshape it. Using this technique, you are reshaping the cornea to better focus light into the eye and onto the retina, providing clearer vision than before. People who are nearsighted, farsighted or have astigmatism can benefit from LASEK. With nearsighted people, the goal of the excimer laser is to flatten the too-steep cornea and with farsighted people, the goal is to steepen a too-flat cornea. When correcting astigmatism the excimer laser smoothes the warped cornea into a more normal shape.
