For nearly a year, cataracts have clouded out all sight from the 70-year-old grandmother's world. With no money, she assumed she'd die alone in darkness. But now she waits quietly outside the operating room for her turn to meet Nepal's God of Sight. More than 500 others - most of whom have never seen a doctor before - have traveled for days by bicycle, motorbike, bus and even on their relatives' backs to reach Dr. Sanduk Ruit's mobile eye camp. Each hopes for the miracle promised in radio ads by the Nepalese master surgeon: He is able to poke, slice and pull the grape-like jelly masses out of an eye, then refill it with a tiny artificial lens, in about five minutes. It's an assembly-line approach to curing blindness that's possible thanks to a simple surgical technique Ruit pioneered, allowing cataracts to be removed safely without stitches through two small incisions. Once condemned by the international medical community as unthinkable and reckless, this mass surgery in the bush" started spreading from Nepal to poor countries worldwide nearly two decades ago. Thousands of doctors - from North Korea to Nicaragua to Nigeria - have since been trained to train others, with the hope of slowly lessening the leading cause of blindness that affects 18 million people worldwide. No one pays for anything, and the entire cost is about $25 per surgery. That's $12,750 for all 510 patients, equal to only about three or four surgeries in the U.S.
