Crystalens® is:
The first and only FDA-approved accommodating intraocular lens.
The only FDA approved intraocular lens that uses natural focusing
ability.
The only FDA approved presbyopia correcting IOL for cataract
patients
that provides
a single focal point throughout a continuous
range of vision |
|
|
| |
|
Crystalens® was the first presbyopia
correcting IOL introduced into the United States market. 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. |

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. talens
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.

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. |

Few patients with crystalens have experienced problems with glare,
halos and night vision. crystalens 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® was proven in clinical trials:
Significantly more patients implanted with a crystalens (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. More than 100,000 crystalens
implants have been implanted worldwide, and that number is growing
daily.
crystalens accommodates like the natural lens. After implantation of
crystalens, most patients will see brighter and clearer from
distance, intermediate to near like they did when they were younger.
