The ReSTOR^® lens uses an innovative apodized diffractive technology to provide a full range of vision. It works like two lenses in one. Combining refractive technology for distance vision and apodized diffractive technology for near vision through a series of concentric rings, the ReSTOR lens allows light from both distance and near objects to focus clearly on the retina. This is something that many cataract patients would otherwise have to achieve by wearing reading glasses. For further information click here, or visit www.acrysofrestor.com.
