Cataract Surgery
Cataract surgery is performed to treat cataracts. Cataracts can cause blurry vision and
increase the glare from lights. If a cataract makes it difficult for you to carry out your
normal activities, your doctor may suggest cataract surgery.
When a cataract interferes with the treatment of another eye problem, cataract surgery
may be recommended. For example, doctors may recommend cataract surgery if a
cataract makes it difficult for your eye doctor to examine the back of your eye to monitor
or treat other eye problems, such as age-related macular degeneration or diabetic
retinopathy.
In most cases, waiting to have cataract surgery won't harm your eye, so you have time
to consider your options. If your vision is still quite good, you may not need cataract
surgery for many years, if ever.
Risks
Complications after cataract surgery are uncommon, and most can be treated
successfully.
Inflammation
Infection
Bleeding
Swelling
Drooping eyelid
Retinal detachment
Glaucoma
Secondary cataract
Loss of vision
Your risk of complications is greater if you have another eye disease or a serious
medical condition. Occasionally, cataract surgery fails to improve vision because of
underlying eye damage from other conditions, such as glaucoma or macular
degeneration. If possible, it may be beneficial to evaluate and treat other eye problems
before making the decision to have cataract surgery.
You may be instructed not to eat or drink anything 12 hours before cataract surgery.
Your doctor may also advise you to temporarily stop taking any medication that could
increase your risk of bleeding during the procedure. Let your doctor know if you take
any medications for prostate problems, as some of these drugs can interfere with
cataract surgery.
Antibiotic eyedrops may be prescribed for use one or two days before the surgery.
Other precautions
Normally you can go home on the same day as your surgery, but you won't be able to
drive, so arrange for a ride home. Also arrange for help around home, if necessary,
because your doctor may limit activities, such as bending and lifting, for about a week
after your surgery.
What you can expect
Before the procedure
A week or so before your surgery, your doctor performs a painless ultrasound test to
measure the size and shape of your eye. This helps determine the right type of lens
implant (intraocular lens, or IOL).
Nearly everyone who has cataract surgery will be given IOLs. These lenses improve
your vision by focusing light on the back of your eye. You won't be able to see or feel
the lens. It requires no care and becomes a permanent part of your eye.
A variety of IOLs with different features are available. Before surgery, you and your eye
doctor will discuss which type of IOL might work best for you and your lifestyle. Cost
may also be a factor, as insurance companies may not pay for all types of lenses.
IOLs are made of plastic, acrylic or silicone. Some IOLs block ultraviolet light.
Some IOLs are rigid plastic and implanted through an incision that requires several
stitches (sutures) to close.
However, many IOLs are flexible, allowing a smaller incision that requires few or no
stitches. The surgeon folds this type of lens and inserts it into the empty capsule where
the natural lens used to be. Once inside the eye, the folded IOL unfolds, filling the
empty capsule.
