Raj Kaliya Dhanuk lies still on a bed with weights on her eye after receiving local anesthesia at Hetauda community eye hospital, in Hetauda, Nepal. Dhanuk and 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. Nepalese master surgeon Ruit estimates sight has been restored to 3-4 million people through his assembly-line approach.
