Cataracts: symptoms and treatment

What is a cataract?

A cataract in the eye occurs when the lens, a small transparent disc inside the eye, develops cloudy patches.

A cataract can cause reduced vision and eventually blindness if left untreated it can occure in one or both eyes. Many people who reach old age will develop a cataract, while some groups of people are more likely to suffer from cataracts than others, including:

• Older people – it’s estimated that 1 in 3 people over the age of 65 suffer from cataracts.
• People with a family history of this medical condition
• A blow to the eye- a blow can occasionally cause a traumatic cataract
• People who suffer from conditions such as diabetes 
• People who take certain medications or smoke- especially smoking can speed up the progression of certain types of cataract

How do I know if I have a cataract?

Cataracts are painless and their symptoms can vary from person to person. They may include:

• Blurred vision
• A gradual loss of colour vision - objects appear duller
• Difficulty reading
• Poor vision in low light situations
• Frequent changes of prescription glasses
• Double vision, even with only one eye open

These symptoms do not always indicate a cataract, however, you should always visit your Optician if you’re worried.

Is there a treatment available for cataract?

A cataract in the eye can be treated by a routine operation. The cloudy lens is removed and replaced by a synthetic one. The operation is usually carried out as an outpatient procedure. It has a high success rate in improving your eyesight and it can take from 2 to 6 weeks to fully recover.
