1. What is cataract?

A cataract is a clouding of the natural lens, the part of the eye responsible for focusing light and producing clear, sharp images. The lens is contained in a sealed bag or capsule. As old cells die they become trapped within the capsule. Over time, the cells accumulate causing the lens to cloud, making images look blurred or fuzzy. For most people, cataracts are a natural result of aging. In fact, they are the leading cause of visual loss among adults 55 and older. Eye injuries, certain medications, and diseases such as diabetes and alcoholism have also been known to cause cataracts.

A cataract is a cloudy area in the lens of the eye. A normal lens is clear and focuses light into the back of the eye. When a cataract develops some of this light is blocked out and or scattered. As this cataract develops, it becomes harder for a person to see.

Most people with cataracts have a cataract in both eyes. However, one eye may be worse than the other because each cataract develops at a different rate.

2. What Are the Symptoms of a Cataract?
Here are some signs of a cataract:

  • Cloudy, fuzzy, foggy, or filmy vision.
  • Changes in the way you see colours.
  • Problems driving at night because headlights seem too bright.
  • Problems with glare from lamps or the sun.
  • Frequent changes in your eyeglass prescription.
  • Double vision.
  • These symptoms also can be signs of other eye problems.

3. How is a Cataract Treated?
A change in your glasses, stronger bifocals, or the use of magnifying lenses may help improve your vision and be treatment enough. With time glasses will no longer work. The way to surgically treat a cataract is to remove the lens and replace it with an artificial lens.

Just because you have a cataract does not mean it must be removed immediately. Cataract surgery should be put off until you are no longer satisfied with the way you see. We don’t do cataract surgery on eyes that see well.

Most people have plenty of time to decide about cataract surgery. Your doctor cannot make your decision for you, but talking with him can help you decide if you are ready for surgery on not.


4. Cataract surgery:

There are two types of surgery to remove lenses that have a cataract:


1. Extra capsular surgery:
The eye surgeon removes the lens, leaving behind the back half of the capsule (the outer covering of the lens).
