Crystalens® is an accommodating intraocular lens implant which
is used to provide a continuous range of vision for far away, intermediate,
and close-up distances. It turns back time by minimizing the eye's
natural process of accommodation and reducing or eliminating your
dependence on contact lenses, bifocals or reading glasses.

The Key-Whitman Advantage
When talking about their vision, most people over the age
of 45 "focus" on the loss of near vision generally associated with presbyopia
or "aging eyes." What they may not realize is that, in addition to developing
cataracts, the inevitable progression of presbyopia weakens the ability
of the lens to focus in the field of vision that begins at our fingertips
- known as intermediate vision. And, until now, this field of vision that
has become the most important for today's active Boomers was severely compromised.
As it turns out, we live most of our "visual lives" in the intermediate
range of distance between 26 and 32 inches. In fact, most of our daily lives
are lived in the intermediate, also known as "lifestyle vision." Activities
falling within our "lifestyle vision" include:
Reading facial expressions during a conversation across a table
Seeing products and prices while walking down the grocery aisles
Using a computer keyboard and looking up at the monitor
Reading the speedometer and other dashboard gauges while driving
Putting a golf ball on the tee
Baiting a hook for fishing
Shaving or putting on make up
Playing billiards or cards
Seeing what is on the dinner plate - and the silverware to use to
Writing a letter or checks to pay bills
Brushing a child's hair
Playing the piano
Measuring ingredients for cooking and baking
Dialing a cell phone or using a hand-held computer
For those struggling with presbyopia and cataracts, there is a new option
to the traditional, standard IOLs used to replace the eye's natural lens:
the Crystalens®. As the most advanced intraocular lens available, the
Crystalens® is the only accommodative, or naturally focusing, lens available
today. Standard IOLs are "fixed" within the eye and correct vision at a
single focus (usually distance). Multifocal lenses, first introduced in
1998, add near vision to the picture but also neglect the intermediate field
of vision. The Crystalens® IOL is the clear choice for patients seeking
to not only preserve their intermediate vision, but have a continuous range
Clinical data show that 100 percent of Crystalens® patients had
good intermediate vision (26" to 32").
The FDA safety and effectiveness clinical data on the most recent
multifocal IOL lenses shows that at a distance of 70 cm (27.5"), the
percentage of eyes achieving 20/20 or better uncorrected vision and
20/25 or better distance corrected vision was "significantly worse"
than the control group.
Multifocal lens technology is based upon splitting light rays between
distances to emphasize near and distance vision while providing little
or no support for intermediate vision. Consequently, the vision provided
by multifocals is stepped, requiring patients to overcome a gap in their
range of vision.
The Crystalens® uses the natural focusing muscles to accommodate
the full range of vision. As a result, 100 percent of the light rays
are focused at each distance so patients see clearly near, far and everything

Risks & Complications
The contemporary treatment for cataracts is to remove the crystalline
lens and replace it with an implantable lens. The Crystalens® represents
the state-of-the-art in implantable lens design and is the result of over
50 years' evolution in the treatment of cataracts.
The medical procedure to implant the Crystalens® is the same safe,
proven cataract surgery performed annually on over 7 million eyes globally.
Over 40 million procedures have been done in the last 25 years. But because
it is surgery, it is not completely risk-free.
Complications of cataract surgery range from minor, usually temporary
side effects, to sight-threatening complications. Fortunately, significant
sight-threatening complications are extremely rare, and include, but are
not limited to, infection, hemorrhage, and retinal detachment. These and
other complications may occur as a result of the removal of a cataract,
whether or not an intraocular lens is implanted, and may result in poor
vision, total loss of vision, or loss of the eye. Dislocation of the lens
and the need for additional surgery, such as lens removal and replacement
are also possible risks of the procedure. In addition, people with existing
medical conditions such as diabetes, high blood pressure, chronic inflammatory
conditions, and chronic infections are at a higher risk of developing complications.
Current data indicates that 98% of people have no complications after
cataract surgery and more than 95% have improved vision. The trusted medical
team at Key-Whitman Eye Center will perform a thorough examination and fully
inform you of any increased risk of a complication.

What about my middle vision, like working on the computer. Will
it be like wearing trifocals?
Your ability to see at approximately arm's length (middle vision) will
be greatly enhanced with the Crystalens®. Over 96% of people enrolled
in the clinical study were able to see 20/20 at arm's length without correction.
In addition, the quality of vision compared to wearing trifocals is significantly
improved. You will have a full range of vision, without having to tilt your
head to find that portion of your glasses that allows you to see clearly.
You simply look at something and the Crystalens® will automatically focus
your eye at near, arm's length, or distance. The Crystalens® mimics the
natural focusing ability of your eye.
Will I be able to read in all light conditions?
The Crystalens® functions very much like the normal human lens. It
is important to remember that reading vision in low light is also influenced
by the overall health of your eye and by the condition of the light sensors
in the retina. As we get older our ability to see in low light conditions
may start to decrease. It is always best to read in good light conditions.
Should I have the Crystalens®HD® implant put in both eyes?
Your doctor will look at a number of factors in deciding which eye to
implant first and when, if necessary, to implant the other eye. Most surgeons
prefer to wait two to three weeks between surgeries, but this may vary based
on how well the first eye is healing and the visual outcome.
How long will the surgery take? Will I feel anything?
The Crystalens® procedure is typically performed in an outpatient
surgical facility. You will arrive at the surgery center about an hour before
the procedure. A number of topical drops will be placed in your eye and
you may be administered medications to help you relax. The eye drops anesthetize
your eye and dilate your pupil.
Once in the surgery suite, you will lie down on a comfortable bed, a
microscope will be positioned over your eye and you will be asked to look
up into the light of the microscope.
The actual surgery usually takes less than 20 minutes. The surgeon will
stabilize your eye with a device to keep your eyelids open. You will feel
no pain, only slight pressure on your eye. All you have to do is relax and
Once the surgery is complete, additional drops will be placed in your
eye to prevent infection, decrease inflammation, and keep your pupil dilated.
A patch may be placed over your eye and someone will need to drive you home.
Once at home, you should rest for the remainder of the day. You should avoid
any strenuous activities. Your doctor will see you the day after surgery
to remove the eye patch and examine your eye. Do not rub your eye. The doctor
will give you additional medications that you will need to put in your eye
for the next week or two. These drugs help the eye heal, leaving no residual
What will my vision be like after surgery?
Your distance vision will usually be very good within a day or two after
surgery. However, your middle and near vision may be somewhat blurred at
first. You may need to wear reading glasses to help you read during this
After about 2 weeks, you will notice that your middle (arm's length)
vision is improving and your near vision is also starting to get better.
It is important that you discontinue the use of the reading glasses at this
time so that you strengthen the focusing muscle of your eyes.
It may take several months for your eyes to reach their full focusing
potential. The more you try to read without reading glasses, the quicker
you will be able to read without them. You may notice a difference in your
vision from one eye to the other after your eyes heal. This is normal. If
the difference in your vision is significant, your doctor may recommend
additional corneal refractive surgery. This is often done for the correction
of astigmatism after implant surgery.
Everyone's focusing ability is different. Most people will be able to
see clearly in the distance, have excellent middle vision, and will be able
to 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.
Your doctor will thoroughly discuss the restoration of your vision after
surgery and will recommend a specific plan for optimizing your uncorrected
vision for near and far. It is important to remember that while virtually
everyone experiences much improved vision after cataract surgery, some people
will have better uncorrected vision than others.
It may be necessary for some people to wear glasses for distance and/or
near vision to obtain optimal visual acuity. The difference from standard
lenses is that most people will not be dependent on these supplemental vision
aids to function normally.
Since this information isn't intended to replace the advice of a health
care professional, be sure and talk with your doctor before making any decisions
regarding vision correction procedures. The long-term safety and effectiveness
of this lens have not been established.
What can be done if my implant does not provide sufficient focusing
There are various reasons why the power of your implant may not be sufficient
to provide you with a continuous range of vision, including, but not limited
to, measurement error, prior refractive surgery, e.g., LASIK, RK. In these
cases, your doctor will decide the best course of treatment, which may include
additional surgeries, such as removal and replacement of the
What about glare, problems driving at night and sensitivity to
light? Can implant surgery create these problems?
These symptoms are much less likely to occur with Crystalens® than
any other presbyopia-correcting lens. These symptoms can be produced or
exacerbated by cataract surgery. Many people report these problems before
cataract surgery and even after surgery; however, they are rarely debilitating.
Sensitivity to light is often a temporary symptom. The Crystalens®
optic material is so clear that in some people it takes time to get used
to how bright colors are and how intense lights can be, particularly at
night. As with any intraocular lens, glare can be a problem at night when
the pupil widely dilates and occasionally light can reflect off the edge
of the implant and create a flash or halo of light. This typically does
not occur in your central field of vision, but rather in the periphery.
People who have worn contact lenses in the past may be familiar with this
phenomenon. Again, glare is rarely debilitating and if it does bother you,
there are a number of things that your doctor can do to improve your vision
at night including medications or night driving glasses.
When will I be able to return to normal activities after
Typically, you will be able to return to normal activities within several
days after implantation with some limitations. Your eye may be sensitive
to touch and bright light, but you should be able to drive and return to
work in two to three days.
Your doctor will provide you with medications to prevent infection and decrease
inflammation, and may provide a protective shield to cover your eye while
sleeping. A pair of plastic, disposable sunglasses will decrease your sensitivity
to light as well as providing protection during the day.
It is important that you avoid heavy lifting or straining that would
increase the pressure in your eye for several days after surgery. You also
must avoid rubbing or pushing on your eye. You should refrain from activities
that could increase your chances of getting hit in the eye. Wear your protective
sunglasses when outdoors. You can shower and wash your hair as long as you
avoid getting soap or shampoo in your eye. Refrain from using eye makeup,
lid liner, and mascara for several weeks after implantation. You should
avoid public swimming pools, hot tubs, or other sources of bacterial contamination
for several weeks. Consult your doctor on recommendations for specific activities.
How often do I need to have my eyes checked after surgery?
Your doctor will advise you as to how often your eyes need to be checked.
Typically, the doctor will see you one day after surgery, after 2 to 4 weeks,
and again around 3 to 6 months after surgery. Thereafter, an annual exam
is usually sufficient unless you have a specific problem.
Will I have to have cataract surgery again?
Once your cataracts are removed and replaced with an implantable lens,
you will never have to have cataract surgery again. Occasionally, several
months after the lens has been placed in the eye, the vision may start to
become cloudy once again. This is sometimes called a secondary cataract
and refers to the clouding of the membrane that surrounds the implant.
This membrane (the capsular bag) originally surrounded the human lens.
When the cataract was removed, all that remained was this membrane into
which the artificial lens was implanted. The membrane healed around the
artificial lens, securely holding it in place in the eye. Unfortunately,
sometimes the same conditions that caused the original cataract will cause
the build up of cells on the membrane behind the implant. These cells will
block the vision and have to be removed.
A laser is used to make an opening in the membrane behind the implant,
immediately improving vision. This is done painlessly without an anesthetic
and takes just a few minutes. Once this is done, no further surgery related
to your cataracts will be required.
I have dry eyes. Will lens implantation help this condition or
will I still have to use artificial tears?
Implant surgery typically will have very little influence on chronic
dry eyes. This condition is related to a variety of internal and external
medical conditions and is sometime associated with aging. You should consult
your doctor on a therapy that is most suited to the cause and severity of
your condition as well as your lifestyle.
What will the Crystalens® procedure cost? Will insurance cover
any of it?
Since each patient's vision is different and unique, the cost for the
Crystalens® procedure will vary. Insurance coverage varies greatly from
policy to policy and state to state. Generally speaking, private insurance
may cover the cataract surgical procedure and anesthesia and may also allow
a certain additional amount for the artificial lens implant. The insured
is then required to pay a deductible as well as any additional amount above
the primary coverage.
(Some patients are completely responsible for
payment - not all insurance companies will cover some of the patient cost).
Payment for conventional IOLs furnished in an outpatient setting is covered
by Medicare. However, providers have generally not offered beneficiaries
presbyopia-correcting IOLs because the costs for this advanced technology
substantially exceed Medicare's payment.
A Medicare beneficiary may request insertion of a presbyopia-correcting
IOL in place of a conventional IOL following cataract surgery. In this case,
the presbyopia-correcting IOL device and associated services for fitting
one lens are considered partially covered by Medicare. The beneficiary is
responsible for payment of that portion of the charge for the presbyopia-correcting
IOL and associated services that exceed the charge for insertion of a conventional
IOL following cataract surgery.
