If you have cataracts, things can start to look dim, blurred or distorted, as if you’re looking through dirty glass. Your vision may seem cloudy, and it can also be hard to make out details or colours.
Try our vision simulator to see what the world looks like when you have cataracts.
Cataract surgery for adults is carried out under local anaesthetic. The procedure usually takes as little as 20 minutes to complete.
Watch a time-lapse of the surgery
During the operation, the clouded lens is removed and replaced with an artificial lens. If a patient has cataracts in both eyes, they will have separate operations for each eye.
After cataract surgery, the patient’s vision starts to return within a few hours. After post-operative checks, their bandages are removed and they can usually go home the same day.
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 aim to improve community health programmes and increase the number of surgeons, nurses and community workers trained in eye health, as well as educating people about cataracts and explaining where to get treatment.
Since our work began in 1950, Sightsavers has helped to provide 7.7 million cataract operations in poorer countries, and trained more than 1,000 surgeons to perform the operations.
But we need your help to save the sight of people with cataracts: donating to our charitable cause can help to change lives. 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.
