How does the CrystaLens work?
The Crystalens accommodating intraocular lens is engineered
with a hinge designed to allow the optic, or part of
the lens that you see through, to move back and forth
as you constantly change focus on images around you.
All other IOL's are fixed and stationary within the
eye - a design that prevents them from accommodating,
or moving to focus. The Crystalens is unique because
it can move.
Crystalens mimics the natural accomodation of a youthful
eye.
Near and intermediate vision result from the action of the focusing
muscle in the eye, called the ciliary muscle. This muscle changes the
power and thus the focus of the natural lens. This enables the eye
to automatically focus to provide distance, intermediate, and near
vision.
How Well Does the Crystalens Work?
In FDA clinical trials Crystalens patients
enjoyed life-changing benefits. More than
98% of patients who received Crystalens implants
in both eyes had uncorrected visual acuity
of 20/30 or better at distance without glasses,
and could read 6 point type on a medicine
bottle. Also, 92% had distance visual acuity
of 20/25 or better. In Europe and Mexico,
where the lens has been in use for five years,
nearly all patients continued to enjoy this
range of vision year after year. In these
studies 93.8% of patients surveyed said they
could perform most daily activities without
glasses.
Thanks to Crystalens, people may no longer
have to put up with impaired or diminishing
vision. And, cataract and refractive surgeons
have a new way to provide this growing population
of aging but youthful people with the rejuvenating
effects of high-performance vision without
glasses or contacts.
