A Visual Device that Differentiates Light and Darkness Arrives at North Carolina, First Time

Duke Eye Center in North Carolina gets to make use of the Retinal Prosthesis for the first time. The device used known as the Argus II Retinal Prosthesis System , though does not restore the normal vision, was said to provide light-and-darkness differentiation.

A 66-year old man named Larry Hester, who was blind for half of his life from having a condition called retinitis pigmentosa, was implanted with an electronic simulator in his left eye September 2014.

On the 1st of October of the same year, Dr. Paul Hahn, Duke eye surgeon, turned it on for the first time.

“It was incredible. It was bright. And it was significant. It is hard to articulate what I was feeling,” was what Hester said.
