Cataracts
Many years ago, cataract surgery involved
an overnight stay in the hospital and a lengthy recovery period.
Now, we offer advanced microscopic surgical techniques and
convenient outpatient facilities to make cataract surgery
comfortable with minimal discomfort and disruption of your
lifestyle. In addition, we offer the latest in implant technology
including wavefront implants, multifocal implants and toric
(astigmatic-correcting) implants. With the rapid development
of new technologies, surgeons are able to customize the choice
of the implant to need the needs of each individual. We participate
in clinical research and advanced courses to make the latest
technologies available to our patients. Both our surgeons,
Dr. Musto and DeBroff are on the clinical faculty of a major
university and have been teaching cataract surgery techniques
to residents for many years. In addition, our doctors will
be part of your entire experience from the preoperative evaluation
and counseling to the surgery and postoperative care. Our
goal is to work with each individual patient and help educate
them to the full spectrum of choices available including the
expected benefits and potential risks, so we can together
make an informed choice of the best method to improve the
quality of vision and the quality of life.
What is a Cataract?:
A cataract is a clouding of the normally clear lens of the
eye.
Symptoms of Cataracts:
1) Blurred or Cloudy Vision
2) Difficulty Reading
3) Loss of Depth Perception
4) Glare from headlights or sunlight
5) Faded perception of colors
6) Difficulty seeing at night
7) Shadowy images
8) Double vision
9) Frequent changes in glasses or contact lenses
Causes of Cataracts
As we age the protein in the lens which is normally arranged
in a very precise manner, undergoes chemical changes to cloud
part or all of the lens. 80% of people over the age of 65
have some lens clouding attributable to age. Many factors
have been implicated in causing senile cataracts from lack
of vitamins to UV light, but other reasons for cataracts include
eye injury, certain eye diseases (uveitis), medical conditions
like diabetes, heredity, birth defects, medications (steroid,
or even steroid inhalers), and smoking.
Treatment of Cataracts
Surgery is the only treatment for cataracts. Cataract surgery
is one of the most effective and safest procedures performed
today and involves removing the cloudy lens and replacing
it with a substitute implantable lens (Intraocular lens or
IOL). Cataracts are not treated with lasers. If the cataract
is small and not bothering the vision, surgery may be postponed
and a change in glasses may be sufficient. If you have cataracts
in both eyes, surgery is never done at the same time.
When Should you have Cataract Surgery
You decide when it is right to have surgery. You can postpone
surgery until the cataract interferes with your vision. Because
everyone’s visual needs are different, this point may
differ from one person to another. It is not necessary to
wait until the cataract is “ripe” or totally opaque
before having it removed. During your evaluation, you will
be told if you are a candidate for surgery and how much improvement
in vision you can expect from surgery that is free of complications.
There are certain rare circumstances that may require cataract
removal regardless of vision, for example if the lens begins
to break down or become overripe or is releasing products
that may cause glaucoma or if the cataract is preventing observation
or treatment of another eye condition.
How is the Cataract Removed?
Most cataract surgery today is performed using a technique
called Phacoemulsification (Phaco). We make a very small incision
(less than 3 millimeteres) on the side of the cornea, the
clear dome shaped surface that covers the front of the eye.
A microscopic probe is placed through the inicision and ultrasound
waves soften and liquefy the lens so it can be removed by
gentle suction. If the cataract is very dense, a technique
called Extracapsular Surgery may be needed in which we make
a larger incision to remove the hard center of the lens. In
almost all cataract surgeries, the removed lens is replaced
with an Intraocular Lens (IOL). The IOL is permanently implanted
in the eye; you cannot feel it or see it and it is not noticed
by others.
Multifocal Implants (IOL’s)
IOL’s come in 2 varieties: monofocal and multifocal
Originally all IOL’s were monofocal, or corrective of
vision at one distance only, whether near, intermediate, or
far. Since they correct vision at just one distance, glasses
are still needed. Newer, multifocal IOL’s will correct
vision at multiple ranges and may eliminate the need for glasses
(approximately 80% of patients may never have to wear glasses
or bifocals again).
There are 2 types of multifocal IOL’s currently available:
The ReZoom IOL:

and
The Restor IOL:

After Surgery
Vision often improves quickly (within days) and you may be
surprised at how good it becomes. It does not become stable
until about 4 weeks after surgery, at which time eyeglasses
may be fitted to give you the best correction for distance
vision and reading. No surgical results can be guaranteed.
Your vision after surgery will likely be fine but it will
depend on the basic health of the eye. Retina and glaucoma
problems can also affect the vision.
