Larry Hester was 33 years old when doctors diagnosed him with retinitis pigmentosa, a disease where the eyes’ light-sensitive retinas deteriorate. He became blind. But thanks to his high-tech retinal prosthesis from North Carolina’s Duke Eye Center, the 66-year-old is seeing things in an entirely new way.
A video posted Oct. 7 captured the moment when Hester’s eye surgeon, Dr. Paul Hahn, turned on the device’s electronic stimulator for the first time since he implanted the sensor last month. Hester immediately flinched, literally taken aback by the sudden sight of light after three decades of darkness.
According to the Duke Medicine blog, Hester is the seventh person in the United States to receive the retinal prosthesis, which gives him the ability to differentiate between light and dark spots within its field of vision.
