Mayo Clinic patient’s first impressions with bionic eye

68-year-old former chemist Allen Zderad from Minnesota sees his wife for the first time in a decade after becoming the fifteenth person in the country to receive a "bionic eye" implant. Zderad can't see the details of people's faces, but he can make out forms and shapes...

Raymond Iezzi Jr., a Mayo Clinic researcher and ophthalmologist, was researching the "Second Sight Argus II" retinal prosthesis system when he encountered Zderad and decided the grandfather of ten would be a good candidate for an implant. Iezzi installed 60 electrodes in Zderad's eye, which interact with a camera in Zderad's glasses and a wearable computer pack to send information to the electrodes implanted in his retina, which then sends signals straight to the optic nerve, Iezzi explained to NBC affiliate KARE.
