Cataract Surgery
What is a cataract
A cataract is a clouding of the normally clear lens of the eye. It can be
compared to a window that is frosted or yellowed.
Misconceptions about cataract
Cataract is not:
- caused by overusing the eyes;
- spread from one eye to the other;
- a cause of irreversible blindness.
Common symptoms of cataract include:
- a painless blurring of vision;
- glare, or light sensitivity;
- double vision in one eye;
- needing brighter light to read;
- fading or yellowing of colors.
The amount and pattern of cloudiness within the lens can vary. If the cloudiness
is not near the center of the lens, you may not be aware that a cataract is present.
What Causes Cataract?
The most common type of cataract is related to aging of the eye. Causes
of cataract include:
- medical problems, such as diabetes;
- medications, especially steroids;
- long-term, unprotected exposure to sunlight;
How is a Cataract Detected?
A thorough eye examination by your ophthalmologist (Eye M.D.) can detect
the presence of a cataract, as well as any other conditions that may be causing blurred
vision or other eye problems.
Problems with other parts of the eye (eg, cornea, retina, optic nerve) can be responsible
for vision loss and may prevent you from having much or any improvement in vision after
cataract surgery. If improvement in your vision is unlikely, cataract removal may not be
recommended. Your ophthalmologist can tell you how much visual improvement is likely.
How Fast does a Cataract Develop?
How quickly the cataract develops varies among individuals, and may even
be different between the two eyes. Most age-related cataracts progress gradually over a
period of years.
Other cataracts, especially in younger people and people with diabetes, may progress rapidly
over a short time. It is not possible to predict exactly how fast cataracts will develop
in any given person.
How is Cataract Treated?
Surgery is the only way a cataract can be removed. However, if symptoms
of cataract are not bothering you very much, surgery may not be needed. Sometimes a simple
change in your eyeglass prescription may be helpful.
There are no medications, dietary supplements or exercises that have been shown to prevent
or cure cataracts.
Protection from excessive sunlight may help slow the progression of cataracts. Sunglasses
that screen out ultraviolet (UV) light rays or regular eyeglasses with a clear, anti-UV
coating offer this protection.
When should Surgery be Done?
Surgery should be considered when cataracts cause enough loss of vision
to interfere with your daily activities. You must decide if you can see to do your job and
drive safely or, if you can read and watch TV in comfort. Can you see well enough to perform
daily tasks, such as cooking, shopping, yard work or taking medications without difficulty?
Based on your symptoms, you and your ophthalmic surgeon should decide together when surgery
is appropriate.
What can I Expect from Cataract Surgery?
Over 1.4 million people have cataract surgery each year in the United States,
and more than 95% of those surgeries are performed with no complications.
During cataract surgery, which is usually performed under local or topical anesthesia as
an outpatient procedure, the cloudy lens is removed from the eye. In most cases, the focusing
power of the natural lens is restored by replacing it with a permanent intraocular lens
implant.
Your ophthalmologist performs this delicate surgery using a microscope, miniature instruments
and other modern technology.
In many people who have cataract surgery, the natural capsule that supports the intraocular
lens becomes cloudy. Laser surgery is used to open this cloudy capsule, restoring clear
vision.
You will have to take eyedrops as your ophthalmologist directs. Your surgeon will check
your eye several times to make sure it is healing properly.
Cataract surgery is a highly successful procedure. Improved vision is the result in over
95% of cases, unless there is a problem with the cornea, retina, optic nerve or other structures.
It is important to understand that complications can occur during or after the surgery,
some severe enough to limit vision. If you experience even the slightest problem after cataract
surgery, your ophthalmologist will want to hear from you immediately.
Cataracts are a common cause of decreased vision, particularly for the elderly, but they
are treatable. The ophthalmic surgeon can tell you whether cataract or some other problem
is the cause of your vision loss and can help you decide if cataract surgery is appropriate
for you.
