What is a cataract?
A cataract is a clouding of part of your eye call the lens. Your vision becomes blurred because the cataract is like frosted
glass, interfering with your sight.

What is the function of the lens?
The lens is a clear tissue found behind the iris, the coloured part of the eye. The lens helps to focus light on the back of the
eye – the retina – forming an image.

What causes a cataract?
Cataracts can form at any age. Most develop as we get older, many people over 60 have some cataract. Long term exposure
to ultra violet light can be a factor. In younger people cataracts can result from conditions such as diabetes, certain
medications and other longstanding eye problems.

How does cataract affect your sight?
Blurry vision:
This is very common. You may notice that your sight has become blurred or misty, or that your glasses appear dirty or

Dazzled by light:
You may be dazzled by lights, such as car headlamps, and sunlight. This can sometimes be alleviated by having spectacles
or sunspectacles with a light tint and UV protection.

Change of colour vision:
Your colour vision may become washed out or faded.

How is a cataract treated?
After being diagnosed by your Optician or GP, do not be alarmed, you will be referred to hospital for cataract removal/
extraction. An operation will take place when the cataract is removed and replaced with a plastic lens. The plastic
lens is called an intraocular lens and remains permanently in your eye. In a vast majority the condition can be treated

You will be given eye drops to use for up to two months after your operation. Most people notice an instant improvement in
their sight, although complete healing may take several months.
