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. 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.

This condition develops when the eye's natural lens focusing system grows more rigid and can no longer move or change shape sufficiently enough to enable sight at all distances.

If you receive a standard IOL during your procedure instead of one that corrects or minimizes presbyopia, you may have great distance vision but likely would need reading glasses following cataract surgery.

The ability to quickly change focus between distances is called “accommodation.” Crystalens is the only accommodating IOL.



These zones are varied proportionally to provide optimal vision under different lighting conditions..

This is because light from far objects needs less refraction (bending) than light from near objects, in order to focus clearly on the retina.

Accommodation happens naturally and automatically as we switch our focus. IOLs to Mimic Accommodation The FDA has approved two multifocal IOLs (Re Zoom® and Re STOR™) and one accommodating IOL (Crystalens).

But, many early lenses demonstrated only moderate patient satisfaction.


Multifocal IOLs attempt to replace a patient’s natural accommodation with multiple fixed images.

Using three different technologies, they provide focused vision in distance, near and mid-ranges, and are used to correct both cataracts and .
