The article summarizes a new book about Aravind Eye Hospital and its unique business model of providing high quality eye care, even though it treats 60% of patients for free or at subsidized rates. The book details how Aravind has remained self-reliant through strategies like manufacturing its own lower-cost intraocular lenses. It discusses the hospital's clear vision of eliminating needless blindness and how founder Dr. V. instilled a sense of purpose in employees. While growing rapidly to serve more people, Aravind focuses on ethics and innovation over profits. The model is described as "upside-down" but highly successful in delivering standard, low-cost surgery.
