cataracts

While a comprehensive eye examination can determine for certain if you have a cataract forming, there are a
number of signs and symptoms that may indicate a cataract. Among them are:

Gradual blurring or hazy vision where colors may seem yellowed;
The appearance of dark spots or shadows that seem to move when the eye moves;
A tendency to become more nearsighted because of increasing density of the lens;
Double vision in one eye only;
A gradual loss of color vision;
A stage where it is easier to see without glasses;
The feeling of having a film over the eyes; and
An increased sensitivity to glare, especially at night.

What is a cataract?
A cataract is a clouding of the normally clear crystalline lens of the eye. This prevents the lens from properly focusing light on the retina at the back of the eye, resulting in a loss of vision. A cataract is not a film that grows
over the surface of the eye, as is often commonly thought.

Why are they called cataracts?
Sometimes cataracts can be seen as a milkiness on the normally black pupil. In ancient times, it was believed
this cloudiness was caused by a waterfall - or cataract - behind the eye.

Who gets cataracts?
Cataracts are most often found in persons over the age of 55, but they are also occasionally found in younger
people, including newborns.

What causes cataracts?
It is known that a chemical change within the eye causes the lens to become cloudy. The change may be due to
advancing age or it may be the result of heredity, an injury or a disease.

Excessive exposure to ultraviolet or infrared radiation present in sunlight or from furnaces, cigarette smoking
and/or the use of certain medications are also cataract risk factors. Cataracts usually develop in both eyes, often
at different rates.

Can cataracts be prevented and treated?
Currently, there is no proven method to prevent cataracts from forming.

If your cataract develops to a point that daily activities are affected, you will be referred to an eye surgeon who
may recommend the surgical removal of the cataract.

Prescription changes in your eyewear will help you see more clearly until surgery is necessary, but surgery is the
only proven means of effectively treating cataracts. The surgery is relatively uncomplicated and has a very high
success rate.

When will I need to have cataracts removed?
Cataracts may develop slowly over many years or they may form rapidly in a matter of months. Some cataracts
never progress to the point that they need to be removed. Usually, you will be ready to have the cataract removed
when it is having a significant adverse effect on your lifestyle.

Our office will arrange a consultation with a surgeon who will decide on the appropriate time for removal. Most
people wait until the cataracts interfere with daily activities before having them removed.

What happens after cataract surgery?
You, along with your doctors, will decide on the type of post-cataract vision correction that you will use. Intraocular
lens implants, inserted in your eye at the time of surgery, serve as a "new lens" and are the most frequent form of
visual correction. In some cases, however, eyeglasses or contact lenses may also be needed to provide the
most effective post-cataract vision.

Cataract surgery has now developed to the point where most procedures are completed in a day and overnight
stays in hospital are unnecessary. The results are usually excellent and patients are often able to appreciate a
significant improvement in vision almost immediately following surgery.
