The eye app that puts simple operation within reach

In the West, cataract surgery is a routine operation. But in rural Africa, people can find it extremely difficult to be diagnosed and treated for the condition - and it can ruin their lives.

The village of Kotyana is home to 72-year-old Ndawayipheli and his wife Nojongile, 68.

Both Nojongile and Ndawayipheli lost their sight because of cataracts - a condition that can be corrected with a 20 minute routine surgery, but for them diagnosis and treatment is difficult to access because of the remoteness of their location.

It was this obstacle of remoteness that Dr William Mapham, an ophthalmology registrar at Tygerberg hospital set out to overcome.
