Crystalens AO is implanted during one of the most commonly performed surgeries in the world. Over 8,000 standard outpatient cataract surgeries are performed in the US daily. This safe and painless procedure also usually has a quick turnaround, as most patients can return to their daily activities almost immediately after surgery.

Key Features & Benefits

  • The first and only FDA-approved accommodating intraocular lens - meaning that it uses the natural focusing ability of the eye

  • Crystalens AO was inspired by the eye’s natural crystalline lens

  • Unlike other lenses, Crystalens AO directs all available light received by the eye to a single focal point, so that you can focus on objects at all distances

Crystalens AO Lens is an artificial lens implant that can treat both a person's cataracts and presbyopia —the clouding or hardening of your lenses, and the loss of near and intermediate vision, respectively. Crystalens was modeled after the human eye. Like the natural lens, it is a lens implant that 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. Many patients hardly, if ever, need glasses after surgery.

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, like your natural lens, flexes as you focus your vision.

Is this product right for you?



The Crystalens is intended for primary implantation in the capsular bag of the eye for the visual correction of aphakia secondary to the removal of a cataractous lens in adult patients with and without presbyopia. The Crystalens provides approximately one diopter of monocular accommodation which allows for near, intermediate, and distance vision without spectacles.


Implantation of Crystalens is a surgical procedure. All surgical procedures entail some risk. The risks of implantation with Crystalens are generally the same potential risks that exist for implanting all intraocular lenses. Because Crystalens has a smaller optic compared to the standard IOL, glare and other visual disturbances may occur under certain lighting conditions, including at night when the pupil widely dilates. Only your surgeon can determine if Crystalens is right for you and explain the applicable risks. Your doctor will perform a thorough examination and fully inform you of any increased risk of complications. Because Crystalens only absorbs a portion of ultraviolet light, you should wear sunglasses with UV400 protection when out in daylight.


Cataract surgery recovery will vary from individual to individual. To ensure the best outcome, it will be important to follow the guidelines provided by your surgeon
