|What is Crystalens HD® ?
Crystalens HD® 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 HD® 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 HD® can reduce or eliminate glasses for most activities including: reading a book, working on the computer, and driving a car.
Crystalens HD® 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 HD® dynamically adjusts to your visual needs.
Crystalens HD® 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 HD® flexes as you focus your vision.
Crystalens HD® is:
- The first and only FDA-approved accommodating intraocular lens
- The only FDA approved intraocular lens that uses the natural focusing ability of the eye
- The only FDA approved presbyopia correcting IOL for cataract patients that provides a single focal point throughout a continuous range of vision
Few patients with Crystalens HD® have experienced problems with glare, halos and night vision. Crystalens HD® focuses only one image to the back of the eye, unlike a multifocal lens that projects multiple images, requiring your brain to “adjust” to the differences.
The effectiveness of Crystalens HD® was proven in clinical trials:
- Significantly more patients implanted with a Crystalens HD® (88.4%) could see better at all distances then patients implanted with a standard IOL (35.9%).
- Most patients have continued to report excellent vision 7 years after implantation with Crystalens HD®. More than 95,000 Crystalens HD® implants have been implanted worldwide, and that number is growing daily.
Crystalens HD® accommodates like the natural lens. After implantation of Crystalens HD®, most patients will see brighter and clearer from distance, intermediate to near like they did when they were younger.
ONLY FDA-Approved accommodating IOL
Crystalens HD® was the first presbyopia correcting IOL introduced into the United States market and is currently the only FDA-approved accommodating IOL. Crystalens HD® addresses the limitations of standard monofocal IOLs and multifocal IOLs by providing the following advantages to patients:
- Provides a Broad Range of Vision:Crystalens HD® 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 HD® 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 HD® 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.
