The long-awaited approval of Alcon Surgical’s ReStor Lens by the Food and Drug Administration (FDA) has finally occurred. The most impressive result of the ReStor Lens is enhanced up close reading. The special lens – made of a proven material called AcrySof – features a series of stair steps that help divide light in a process called “apodization.” The steps in the diffractive structure are larger at the lens center, the step height decreases away from the lens center and the smaller the step, the lower the proportion of energy that is directed to near focus. In other words, the lens helps individuals 40 and older see near, intermediate and far – without corrective eyewear, including reading glasses. Additional benefits are patients will not need cataract surgery and according to other national studies fewer complaints about halos. The root cause of presbyopia (not being able to read fine print after age 40) is the aging of the material in the eye. Previously, LASIK surgeons utilized monovision – correcting one eye for distance, the other for near. But not everyone could tolerate this. Replacing the natural lens with the ReStor lens truly addresses the problem.
