Cegos recuperam parte da visão através de implante na retina. Sensacional

And more good news could be on the way as results from other participants comes to light. But the chip is a bright ray of hope for the estimated 1.5 million worldwide that have retinitis pigmentosa, if not for the 285 million visually impaired.
