During the operation, the clouded lens is removed and a new artificial lens is implanted inside the eye.

We also want to improve the quality of cataract surgery and increase the number of operations that are able to be performed.
To achieve this, we’re working to strengthen community health programmes and increase the number of surgeons, nurses and community workers trained in eye health, as well as educating local people about the condition and explaining where to get treatment.
In 2016, Sightsavers supported more than 260,000 cataract operations around the world. Since our work began in 1950, we have supported 6.6 million cataract operations, and trained more than 1,000 surgeons to perform the operations.
We need your help to save the sight of people with cataracts. An eye examination to screen someone for a range of eye conditions costs less than a cup of coffee, and could be the first step towards restoring their vision.
