Allen Zderad, 68, hadn't seen his wife or grandchildren or much at all in over a decade. This was due to a genetic degenerative eye disease known as retinitis pigmentosa, which meant he slowly lost his sight as the years went by.
But thanks to medical research center Mayo Clinic he was given a bionic eye, the Second Sight Argus II Retinal Prosthesis System, and when it was turned on he was able to see his wife.
Zderad is the 101st person to receive the Second Sight Argus II Retinal Prosthesis System. Watch the video above to see how happy it's made him.
The result is a wonderful hear-felt visual reunion that'll bring a tear to your eyes.
"It's a bionic eye – in every sense of the word. It's not a replacement for the eyeball, but it works with interacting with the eye, explained Dr. Iezzi. "Mankind has been seeking to cure blindness for 2,000 years or more, but only in the past quarter of a century have we had the electronics and the packaging and all the other things come together to build a retinal prosthesis that could restore sight to the blind."
