When asked if he sees his wife in the room, Allen Zderad exclaims, "That's easy, it's the best!" The most beautiful ... Allen speaks with the heart, because his eyes can not to see his wife Carmen. Allen, a retired Minnesota, is one of the first people to receive a bionic system implanted in the eye.
For twenty years, Allen Zderad suffers from retinitis pigmentosa, a degenerative disease that attacks the retina and eventually condemned to a life in the dark. There are about ten years, he became completely blind.
Researchers at the in Minnesota, have released a video where we see Allen regain sight thanks to its implant. He throws himself into the arms of his wife, and the computer on a table conveys the images it receives. Not much to no pun first sight. A dark shape on the screen, this is what Allen actually sees, but he already so happy!
He can see the frame of a door for example, the handle of the fridge, or distinguish how many people are in front of him.
Glasses, a computer, an implant in the eye
The pensioner wearing glasses with a camera that sends video to a laptop computer that processes the data. They are then transmitted wirelessly to a network of electrodes 60 surgically implanted in the patient's eye. The implant sends the lightwave signals to the optic nerve, bypassing the damaged retina. These impulses are interpreted as vision by the brain.
Soon other pathologies concerned
The device proposed by the Mayo Clinic is effective for now only for patients with retinitis pigmentosa, but doctors hope to propose in the future to those who suffer from severe glaucoma, or those who developed blindness due diabetes.
After a decade in the dark, Allen has reviewed Carmen ... and his 10 grandchildren.
