About cataracts

Cataract surgery is the most common operation in the developed world. It occurs when the natural lens of the eye (the crystalline lens) becomes cloudy, usually with age. This can happen over a period of time, as the normal protein structure within the lens deteriorates with age. Less commonly, it can occur relatively quickly.

 Cataracts are not a growth, they are a normal part of the ageing process. In fact, most people with cataracts are healthy and have no other eye problems. They mainly occur in people over the age of 60 (however they can occur in people who are younger – some people are even born with congenital cataracts).

Most at risk are people who have a family history of cataracts, although they have also been linked to other diseases such as diabetes, prolonged exposure to sunlight or related to smoking and alcohol use.

Symptoms of cataracts

As a cataract progresses, the following may occur:

• Deterioration of your far vision or near vision (or both)
• Hazy or cloudy vision
• Decreased night vision
• Sensitivity to light 
• Intolerance to glare
• When increasing the strength of your glasses no longer gives you clear vision  
• A tendency to becoming more shortsighted

If you notice any of the above symptoms occurring, you’ll need to visit your GP or optometrist.

Assessing cataracts

If your GP or optometrist suspects that you have a cataract, you’ll be referred to a specialist ophthalmologist. You can request that you are referred to the ophthalmologist of your choice.
