In this richly detailed and transporting book, David Oliver Relin brings us the story of two doctors-one from Nepal, one from Utah-who have dedicated their lives to eradicating preventable blindness on earth. Relin takes us from improvised plywood operating tables in the farthest reaches of Nepal to state of the art operating theatres at top American universities to show how the work of these two driven men is restoring sight-and hope-to patients across the world. With their revolutionary, inexpensive style of surgery, Geoffrey Tabin and Sanduk Ruit have been able to restore sight to tens of thousands of patients around the world. The people they have helped range from women who need their eyesight so that they can work as seamstresses and feed their families to old men who cannot walk dangerous mountain trails unaided to cataract-stricken children who have not seen their mother's faces for years. Here is the unforgettable story of how two men with a shared dream are changing the world, one pair of eyes at a time.
