iStock/Thinkstock(ANN ARBOR, Mich.) -- Roger Pontz, from Michigan, is the fourth person to be fitted with a kind of bionic eye. He suffers from a degenerative disease.
Doctors spent four and a half hours implanting electrodes on his eye. Electrical impulses are transmitted from the retina to the optic nerve and then the brain, allowing him to see shadows and light.
There’s no sharp focus yet but doctors are calling this a game changer.
