Crystalens Lens Implant.
For Patients with Presbyopia
East Valley Ophthalmology offers the Bausch & Lomb Crystalens lens
implant as a premium lens upgrade from standard
single-focus lens implants. The Crystalens is designed to automatically
move forward and backward with the eye's internal muscle to allow a
greater range of visual focus than traditional lens implants. We invite
you to call to have your questions answered or to make an appointment: 480-981-6111.
The Bausch & Lomb Crystalens Lens Implant
The Bausch & Lomb Crystalens is the first "accommodating" lens
implant to be approved by the FDA, uniquely designed with hinges
on two sides, held in place and moved by the tiny ciliary muscles
inside the eye to enhance focusing ability.
The Crystalens has advanced
focusing capability that best corrects vision for distance and
intermediate, while objects at near distances may still be somewhat
out of focus. Some patients may need reading glasses for small print.
The
Crystalens lens implant is:
- The first and only FDA approved accommodating intraocular
lens prescribed for presbyopia
- The only lens implant that utilizes the natural accommodating ability of
the eye
- The first lens implant to provide a single focal-point throughout a wider
range of vision
The accommodative abilities of the Crystalens result from the focusing
muscle in the eye, called the ciliary muscles. These muscles change
the position and thus the focus of the Crystalens, allowing the eye
to automatically provide a wider range of vision.

Presbyopia — the inability
to accommodate
Presbyopia describes the condition where the eye exhibits a progressively
diminished ability to focus on near objects with age. Most people's
vision remains stable until their late 40's when, at that time, the
eye's natural internal (crystalline) lens begins to gradually enlarge
and harden. It then becomes difficult for the eye to adjust your
lens to focus at varying distances. This is known as "loss of accommodation",
or "presbyopia",
and its earliest symptom is difficulty seeing things
close-up without reading glasses. Generally, reading glasses, bifocals, or trifocals
are the standard solution to presbyopia. However, the
Crystalens lens implant is now an option in cataract surgery to replace
the natural lens when it has lost its ability to accommodate. For most
people the Crystalens greatly reduces their dependancy on glasses.
What makes the Crystalens unique?
In conventional cataract surgery, the surgeon removes the hardened, cloudy
natural lens and implants a single-focus artificial lens, called an "intraocular
lens implant" or "IOL". This lens allows the patient to see well only at one
fixed distance, usually far distance. For close and intermediate vision, patients
would require the use of glasses.
The Crystalens offers the potential to restore much of your eye's natural
focusing ability by incorporating a design corresponding
to the way the natural lens flexes and focuses. The Crystalens has hinges
on both sides so it can be moved by the tiny ciliary muscles inside
your eye, allowing you to focus more naturally at a greater range
of distances than with traditional lens implants.

The Crystalens is implanted in a similar manner to other intraocular
lenses during cataract surgery. Used in conjunction
with standard cataract extraction methods, the Crystalens can potentially restore
a wider range of functional vision, without total
dependence on glasses or contact lenses.
In addition, the ease of vision compared to wearing trifocals is significantly
improved. You will have a wider range of vision without having
to tilt your head to find that portion of your glasses that allows you to see
clearly. Typically, you simply look at something and the Crystalens will automatically
focus your eye, because the Crystalens mimics
the natural focusing ability of your eye.
Everyone's focusing ability is different. Many people will be able to see
clearly in the distance, have excellent middle vision and possibly read
a newspaper without glasses, but some people may be more comfortable with additional
correction, particularly at night or in dim light. It is important to remember
that implant surgery cannot resolve pre-existing visual conditions such as
floaters, flashes, or visual field loss that are a result of conditions of
the eye and not related to the lens.
How Well Does the Crystalens Work?
In FDA clinical trials:
- 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"), 20/20
at arm's length, 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
lens implant (35.9%)
The Crystalens lens is available in a wide range of optical powers
that effectively correct eye that are nearsighted
and farsighted. As each patient is unique, both in physiology
and in viewing distance preferences, the correct
power intraocular lens for your cataract surgery will be selected
using biometry equipment. An in-depth
discussion of your needs and options will take place with your eye
surgeon at East Valley Ophthalmology.
