What causes cataracts and how do you treat them?

Cataracts are where the eye lens develops cloudy patches, causing blurry vision that is like looking through frosted glass. It is usually caused by age but can be accelerated by having diabetes or taking steroids.

The only treatment is surgery, which is generally straightforward and done under local anaesthetic. The surgeon makes a tiny cut, removes the cloudy lens and replaces it with a clear plastic one. The NHS generally offers a fixed lens for either near or distance vision, so you will probably still need to wear glasses. Usually both eyes are treated separately.

Surgery should improve focus and you will experience less glare when looking at bright lights. In terms of risks, there is about a one in 50 risk of serious complications in cataract surgery, including loss of vision or detached retina. However, these can generally be treated.
