Advantage of Crystalens HD

Unlike standard cataract replacement lenses, Crystalens® lenses correct your cataracts and give you back your full range of vision. They flex like your eye's natural lens, allowing you to see better at all distances. If you're like many Crystalens® patients, you'll hardly, if ever, need your glasses or contacts again.

Now what  is Crystalens®? 

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.

What makes the Crystalens® unique? 

In conventional lens implant surgery, which has been the standard treatment for cataracts for many years, the surgeon implants a fixed focus plastic or silicone artificial lens. This lens allows the patient to see well only at distance. For reading vision, patients would require a pair of glasses.

Unlike other intraocular lenses (IOLs), the Crystalens® has the unique ability to focus on objects at varying distances using the eye's natural muscle. This means that the Crystalens® can provide sharper vision, without corrective lenses, potentially throughout a full range of vision from near to far and everything in between.

Standard (single vision) lens implants do not have the ability to provide a full range of vision. Most people who have single vision lens implants MUST wear glasses for middle and near vision. Similarly, most people over the age of 45 who have LASIK have a single range of vision, unless they have one eye treated for distance and one eye corrected for near vision. This type of treatment, sometimes called "monovision" has its own set of limitations and may not be the answer for everyone.

However, the Crystalens® is able to restore your eye's natural focusing ability by using a design that corresponds to the way the natural lens flexes and focuses.

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.
