A cataract
is a clouding of the lens in the eye that affects vision. Most cataracts are
related to aging. Cataracts are very common in older people. By age 80, more
than half of all Americans either have a cataract or have had cataract surgery. A cataract can occur in either or both eyes.
It cannot spread from one eye to the other.
The
lens is a clear part of the eye that helps to focus light, or an image, on the
retina. It works much like a camera lens. It focuses light onto the retina at
the back of the eye, where an image is recorded. The lens also adjusts the
eye's focus, letting us see things clearly both up close and far away. The lens
must be clear for the retina to receive a sharp image. If the lens is cloudy
from a cataract, the image you see will be blurred.
Frequently
Asked Questions about Cataracts
What causes cataracts?
Researchers
suspect that there are several causes of cataracts, such as smoking and
diabetes. Or, it may be that the lens just changes from the wear and tear it
takes over the years.
Who
is at risk for cataract?
The risk of
cataract increases as you get older. Other risk factors for cataract include:
Certain
diseases such as diabetes.
Personal
behavior such as smoking and alcohol use.
The
environment such as prolonged exposure to sunlight.
What are the symptoms of a cataract?
The most
common symptoms of a cataract are:
Cloudy
or blurry vision.
Colors
seem faded.
Glare.
Headlights, lamps, or sunlight may appear too bright. A halo may appear around
lights.
Poor
night vision.
Double
vision or multiple images in one eye. (This symptom may clear as the cataract
gets larger.)
Frequent
prescription changes in your eyeglasses or contact lenses.
If you or a
loved one is experiencing any of these symptoms, contact our office for a
comprehensive eye exam.
How
is a cataract treated?
A cataract
needs to be removed only when vision loss interferes with your everyday
activities, such as driving, reading, or watching TV. You and your eye care
professional can make this decision together. Once you understand the benefits
and risks of surgery, you can make an informed decision about whether cataract
surgery is right for you. In most cases, delaying cataract surgery will not
cause long-term damage to your eye or make the surgery more difficult. You do
not have to rush into surgery.
Surgery involves
removing the cloudy lens and replacing it with an artificial lens. Today's
procedures are simpler, faster and less invasive than ever before. There are many lens options available. From
active to more relaxed lifestyles, we can help you select the lens that best
meets your needs and expectations.
