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.

ONLY FDA-Approved accommodating IOL

Crystalens was the first presbyopia correcting IOL introduced into the United States market and is currently the only FDA-approved accommodating IOL. Crystalens addresses the limitations of standard monofocal IOLs and multifocal IOLs by providing the following advantages to patients:

• Provides a Broad Range of Vision: Crystalens moves and changes shape using the eye’s natural focusing mechanism, instead of remaining fixed and stationary within the eye. This movement, or accommodation, allows the eye to focus on objects across a broad range of distances to reduce or eliminate dependence on glasses. In particular, this accommodation provides significant advantages in addressing intermediate vision.

• Maintains Clarity of Vision: Unlike multifocal lenses, Crystalens directs all available light received by the eye to a single focal point, comparable to that of a healthy natural lens.
• Patient Adjustment Not Required: Crystalens produces a single image consistent with normal vision, meaning patients do not need to neuroadapt to viewing multiple images. Patients also do not need to tolerate or adjust to high levels of halos and glare often associated with multifocal IOLs.
