What is a Cataract?
A cataract is a clouding of the normally clear lens of the eye. The lens, which is located behind the iris, focuses light on the retina at the back of the eye to produce a sharp image. However, when a cataract forms, the lens becomes cloudy, like a frosted window, and light cannot be easily transmitted to the retina. This results in impaired vision.
What are Cataract Symptoms?
Common symptoms of cataract include: blurred vision, sensitivity to light and glare, poor night vision, less vivid perception of colors and loss of depth perception.
As a cataract develops it limits the person’s ability to perform simple tasks- seeing street signs, halos around lights, ghosting images, trouble driving at night, reading and performing close-up work. These symptoms may vary depending on the size and location of the cataract.
What is the treatment for cataracts?
The safe and effective treatment for cataracts is surgical removal. Once the lens of the eye becomes cloudy there is no way to make it clear again.
When should I have cataract removed?
Although the presence of a cataract is not an indication for surgery, a cataract may be removed any time a person’s ability to function normally is impaired. Therefore, if cataracts have caused enough of a loss of sight to interfere with work, hobbies or lifestyle, it is probably time to consider removal.
Do cataracts Re-occur?
No. With surgery the cataract is removed. However, at times, the capsule that holds the new intraocular lens in place may become cloudy. This is called a secondary cataract. If this condition occurs a laser procedure can be used to make an opening in the capsule. This is a simple office based procedure that takes only a few minutes to perform and there are no physical restrictions following the procedure.
