Crystalens accommodates like the natural lens. After implantation of Crystalens, most patients will see brighter and clearer from distance, intermediate to near like they did when they were younger.
Crystalens is an accommodating intraocular lens that, unlike a standard IOL, can treat both a person’s cataracts and presbyopia-loss of near and intermediate vision. You probably noticed in your forties that you started to lose some of your up-close vision and had to start wearing reading glasses. Crystalens not only treats your cataracts (a clouding or hardening of your lens), but can also reduce or eliminate your dependence on glasses. It does so by recreating accommodation similar to your eye’s natural lens. The unique Crystalens can reduce or eliminate glasses for most activities, including: reading a book, working on the computer, and driving a car.
Crystalens was modeled after the human eye. Like the natural lens, it uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. Crystalens dynamically adjusts to your visual needs.
Crystalens is designed to allow the optic, or the central circular part of the lens that you see through, to move back and forth as you constantly change focus on images around you. Crystalens flexes as you focus your vision.
