In fact, millions of people around the world benefit from the Institute's work diagnosing and treating eye diseases. The studies conducted by its staff have also led to the development of innovative devices, and enhanced services for partially sighted, blind, and hearing-impaired people. A few examples of the Institute's accomplishments are highlighted below.
