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.
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.
The Crystalens is implanted in a similar manner to other intraocular
lenses. It can be implanted after the removal
of the crystalline lens using the same technique as modern cataract
surgery. This means your surgery can performed on an outpatient patient
basis and that you can resume your normal work and recreational activities
within a couple of days.
The Crystalens is a new technology that is designed to mimic the
eye's natural ability to focus on distant, middle and near objects.
Used in conjunction with standard cataract extraction methods, the
Crystalens can potentially restore a full range of functional vision,
from distance to reading vision without total dependence on glasses
or contact lenses.
The Crystalens Clinical
Trials:
The Crystalens is intended and FDA Approved for the
visual correction, secondary to the removal of a cataract,
in adult patients with and without presbyopia.
98.4% of patients implanted with the Crystalens
accommodating lens in both eyes could pass
a driver's test without glasses
100% could see intermediate (24" to
30") without glasses, the distance for
most of life's activities
98.4% could see well enough to read the newspaper
and the phone book without glasses
Some patients did require glasses for some
tasks after implantation of the Crystalens
accommodating lens
Significantly more patients implanted with
a Crystalens (88.4%) could see better at all
distances
without glasses
than patients implanted with a standard
IOL (35.9%)
