Crystalens
Crystal Intraocular Multifocal Lens
The Eye’s Crystalline Lens
Unlike most current lens implants, which generally have fixed focal lengths, Crystalens has the ability to move naturally with the eye’s focusing muscle. As the muscle contracts it bulges backwards and increases pressure behind the lens, thus forcing the optic forward, while relaxation of the muscle increases the pressure in front of the optic lens to move the optic backwards. Crystalens has “hinges” that attach to this muscle and allow the lens to move; thus, achieving a range of vision not previously possible with the old-style lenses—and for most without the hassles of glasses or contacts.
ReSTOR Multifocal Lens
ReSTOR Lens close-up
The AcrySof ReSTOR ® lens uses an innovative apodized diffractive technology to provide a 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 only achieve by wearing glasses.
ReZoom Multifocal Lens
The Balanced View Optics™ of the ReZoom™ lens allows the lens to match its performance characteristics with your lifestyle. The special optics distribute light over five zones – the zones then focus light on the retina to provide better vision at distance, intermediate and near. So, if you are in a car looking at a map, it may be possible for you to read the map, the dashboard and the road signs ahead—all without glasses!
