Larry Hester, 66,Êand his eye surgeon Dr. Paul Hahn smile and laugh as Hester’s new bionic eye is turned on for the first time on October 1, 2014. Hester has been blind since his early thirties from a condition calledÊretinitis pigmentosa. While the device does not restore vision in the normal sense, it provides light-and-darkness differentiation. He’s the seventh person in the United States to receive the visual aid since the device, known as the Argus II Retinal Prosthesis System, was approved by the FDA. Duke is only the fourth center in the country to implant the device since approval.
