Crystalens is a multifocal IOL (intraocular lens) that can treat both cataracts and presbyopia. Created by Bausch + Lomb, it is currently the only FDA-approved artificial lens that utilizes a method called accommodation to provide sharper, clearer vision at all ranges of distance for people who have undergone cataract surgery. Many people who require cataract surgery also suffer from presbyopia, which is the loss of near and intermediate vision that occurs as part of the natural aging process. By choosing an artificial lens that can correct both cataracts and presbyopia, patients are typically able to see much more clearly than they did before surgery.
Crysalens behaves like the natural lens of your eye in that it uses the eye muscles to flex and accommodate to focus on objects at multiple distances. This allows many patients to read a book, find items in the grocery store, and take in scenery without the need for glasses. After receiving Crystalens implants, most patients report that they rarely, if ever, need to use corrective lenses. Patients who receive standard monofocal lenses may have great distance vision after surgery, but would most likely need to use reading glasses to see objects in the near range of vision clearly.
