What is a cataract?

A cataract is an opacification of the lens of your eye which is normally clear.

How do you know you have a cataract?

Firstly the change in vision you may experience is usually gradual. Your distance vision even with wearing your normal glasses may become blurry. Lights may become disturbing with symptoms such as haloes or starbursts around lights at night.

Cataract Surgery

You may not be able to read the small print on your TV screen when you are looking at the scores while watching sport. Most cataracts develop gradually so easy on your vision is not really obviously disturbed .After a while your vision will drop. In the early stages bright light and eye spectacles can help you with your cataracts. If a decrease in vision interferes with your daily activities you may have to have cataract surgery. Thankfully cataract surgery is now very safe and advanced, using microincision techniques.

This is the list of possible symptoms you may have if you have a cataract:

  1. Night vision becomes impaired
  2. You may have to change your spectacles or contact lens prescription frequently.
  3. Colours become faded.
  4. Reduction in vision, blurred vision.
  5. Sensitivity to bright lights and sunlight.
  6. Glare and haloes around lights.  

Should you see your doctor?

You should see your ophthalmologist if you start experiencing blurred vision or double vision.

What causes cataracts?

Mostly cataracts will develop as you get older (after 50).Sometimes children are born with a cataract. Injury can also cause your lens to get cloudy as can certain medications such as cortisone. Diabetics also have cataracts developing earlier in life.

Where is your lens located in the eye?

A cataract (which develops in the lens), is situated behind the iris, (which is the coloured brown or green or blue part of your eye). As the lens of your eye ages it gets thicker and harder and scatters light in many different directions so your vision becomes blurred. Usually both eyes are affected but sometimes one is more advanced than the other.
