"?The approval of the CustomVue Monovision LASIK expands permanent vision correction options for nearsighted adults who also have trouble focusing on objects close-up,? said Daniel Schultz, M.D., director of FDA?s Center for Devices and Radiological Health. ?Unlike traditional LASIK, Monovision LASIK may reduce the need for reading glasses in some people over 40.?" "LASIK, or laser in-situ keratomileusis, is a procedure in which the surgeon cuts a flap in the outer layers of the cornea, removes a small amount of the tissue beneath it with the laser, and then replaces the flap. CustomVue Monovision LASIK produces monovision correction in nearsighted (myopic) adults, with or without astigmatism, ages 40 years or older with normal age-related loss of ability to focus on near objects (presbyopia)." "The CustomVue device is designed to correct all nearsightedness in the patient?s dominant eye and only part of the nearsightedness in the non-dominant eye. This allows the patient to use the fully corrected eye for distance vision and the under-corrected eye for seeing close up. After a period of time, the brain adjusts to the difference in perception between the two eyes." "People considering CustomVue monovision LASIK should first wear monovision contact lenses for at least a week to determine if they can tolerate having one eye under-corrected. Following monovision surgery, the two eyes may not work together as well as they did before in some patients, especially in dim light or when performing tasks requiring very sharp vision or fine depth perception. Patients may need to
