Cataract removal is one of the most common operations
performed in the U.S. today. It is also one of the safest and most effective. In
about 90 percent of cases, people who have cataract surgery have better vision
afterward.

There are two primary ways to remove a cataract. Your
doctor can explain the differences and help determine which is best for you:
|
Phacoemulsification, or phaco.
Phacoemulsification is an advanced technique of cataract extraction. It is
also known as small-incision cataract surgery. Others call it the
"no-needle, no-stitch" technique. After application of a local anesthetic,
your doctor makes a small incision on the side of the cornea, the
clear, dome-shaped surface that covers the front of the eye. The doctor then
inserts a tiny probe into the eye. This device emits ultrasound waves that
soften and break up the cloudy center of the lens so it can be removed by
suction. Most cataract surgery today is done by phaco. |
Extracapsular surgery. Your doctor
makes a slightly longer incision on the side of the cornea and removes the
hard center of the lens. The remainder of the lens is then removed by
suction.

After placing topical anesthesia, clear corneal incision is made with a
crystal/diamond keratome. This is usually only 3.0 mm in size. This is a
self-sealing incision which allows a sutureless procedure.

Arguably one of the more delicate steps in the procedure of cataract
removal, continuous curvilinear capsulorhexis (CCC) is the careful creation
of a well-controlled tear in the anterior capsule of the cataract.

Ultrasonic vibrations (phacoemulsification) are now created to crush the
cataract into manageable particles which are then aspirated into a port
using the same tip (handpiece).

The
conventional way of approaching the removal of a cataract is by the "divide
and conquer" method. The cataract is rotated and grooving is continued to
create manageable pie shaped segments.

After removal of the tough nuclear component, the softer cortical material
are then aspirated with an irrigation/aspiration (I/A) handpiece. Complete
removal of the cataract lessens the likelihood of developing an "after
cataract" or posterior capsular opacification necessitating a YAG laser
capsulotomy post operatively.

After injection of
viscoelastic material into the capsular bag and the anterior chamber a
foldable intraocular lens is then inserted and unfolded into the eye.

The intraocular lens is
then dialed into place. The remaining viscoelastic material is removed. The
eye is then checked for leaks.

In most cataract surgeries, the removed lens is
replaced by an intraocular lens (IOL). An IOL is a clear, artificial lens
that requires no care and becomes a permanent part of your eye. With an IOL,
you'll have improved vision because light will be able to pass through it to the
retina. Also, you won't feel or see the new lens. The self-sealing corneal
incision precludes the need for stitches, however, one may receive one or
several stitches in some instances.
Some people cannot have an IOL. They may have problems
during surgery, or maybe they have another eye disease. For these people, a soft
contact lens may be suggested. For others, glasses that provide powerful
magnification may be better.

A week or two before surgery, your eye care
professional will do some tests. These may include tests to measure the curve of
the cornea and the size and shape of the eye. For patients who will receive an
IOL, this information helps your doctor choose the right type of IOL. Also,
doctors may ask you not to eat or drink anything after midnight the morning of
your surgery.
Back to Top
When you enter the hospital or clinic, you will be
given eye drops to dilate the pupil. The area around your eye will be washed and
cleansed.
The operation usually lasts less than 1 hour and is
almost painless. Many people choose to stay awake during surgery, while others
may need to be put to sleep for a short time. If you are awake, you will have an
anesthetic to numb the nerves in and around your eye.
After the operation, a patch will be placed over your
eye and you will rest for a while. You will be watched by your medical team to
see if there are any problems, such as bleeding. Most people who have cataract
surgery can go home the same day. Since you will not be able to drive, make sure
you make arrangements for a ride.

It's normal to feel itching and mild discomfort for a
while after cataract surgery. Some fluid discharge is also common, and your eye
may be sensitive to light and touch. If you have discomfort, your eye care
professional may suggest a pain reliever every 4-6 hours. After 1-2 days, even
moderate discomfort should disappear. In most cases, healing will take about 6
weeks.
After surgery, your doctor will schedule exams to
check on your progress. For a few days after surgery, you may take eyedrops or
pills to help healing and control the pressure inside your eye. Ask your doctor
how to use your medications, when to take them, and what effects they can have.
You will also need to wear an eye shield or eyeglasses to help protect the eye.
Avoid rubbing or pressing on your eye.
Problems after surgery are rare, but they can occur.
These can include infection, bleeding, inflammation (pain, redness, swelling),
loss of vision, or light flashes. With prompt medical attention, these problems
usually can be treated successfully.
When you are home, try not to bend or lift heavy
objects. Bending increases pressure in the eye. You can walk, climb stairs, and
do light household chores.
Back to Top
You can quickly return to many everyday activities,
but your vision may be blurry. The healing eye needs time to adjust so that it
can focus properly with the other eye, especially if the other eye has a
cataract. Ask your doctor when you can resume driving.
If you just received an IOL, you may notice that
colors are very bright or have a blue tinge. Also, if you've been in bright
sunlight, everything may be reddish for a few hours. If you see these color
tinges, it is because your lens is clear and no longer cloudy. Within a few
months after receiving an IOL, these colors should go away. And when you have
healed, you will probably need new glasses.
Back to Top
Sometimes a part of the natural lens that is not
removed during cataract surgery becomes cloudy and may blur your vision. This is
called an after-cataract. An after-cataract can develop months or years
later.
Unlike a cataract, an after-cataract is treated with a
laser. In a technique called YAG laser capsulotomy, your doctor uses a
laser beam to make a tiny hole in the lens to let light pass through. This is a
painless outpatient procedure.
