Larry Hester was diagnosed with retinitis pigmentosa when he was in his early 30s. The degenerative disease blinds patients, and at the time of his diagnosis, there were no known treatments. Mr. Hester is one of several people in the United States to have a bionic eye – an Argus II Retinal Prosthesis Device. The implanted device sends light signals to his brain, allowing him to see for the first time in 33 years. Mr. Hester is eager to provide researchers with information they can use to further enhance the technology so that future generations of patients will benefit from his pioneering effort.
