An estimated 150,000 people in Nepal are blind because of cataracts, but at the same time, Nepal has one of the highest rates of curable blindness anywhere in the world.
One doctor in particular has been making remarkable progress in treating cataracts - and setting the example for many other developing countries, where 90 per cent of the world's blind reside.
Sanduk Ruit, the Nepalese surgeon some call the "God of Sight", has removed 100,000 cataracts over his 30-year career.
As the surgeon's mobile eye camp received patients at a monastery in Dharding, hundreds of people, most of whom had never seen a doctor before, had travelled for days by bicycle, motorbike, bus and even on their relatives' backs to get an appointment.
Al Jazeera's Subina Shrestha visits Ruit's clinic at Phulahari Monastery in remote Dharding, where at the end of the day, it is individual human experience that may be most rewarding of all.
