A Guide to Cataracts
Many of us will experience a cataract during our lifetime. We see patients on a daily basis with this condition and surgical treatment for cataracts is the most common operation carried out in the UK today.
Why do cataracts occur?
A cataract occurs when the crystalline lens in your eye becomes cloudy. They can form at any age but are often associated with getting older. In younger people they can form as a result of an injury, illness, long term condition or as a side effect of medication. There is also evidence to suggest that over exposure to UV light can be a cause.
What are the symptoms?
Cataracts are painless and develop slowly over time. At first, you may experience a slight haze which can become completely opaque in more advanced stages. Common symptoms can include:
-
Blurred or hazy vision
-
A lack of definition in colours
-
Sensitivity to light
-
Poor night vision
