Back bionic eye to see through

now able to distinguish the edges of doors and furniture and read short words

Peter Lane, blind for almost 30 years, was a special receiver implanted in the retina

LONDON - The British cinquantunenne Peter Lane, blind since his early twenties, is thrilled with the results achieved so far after the surgery which it was submitted. The man, who is blind due to a degenerative genetic disease, now is able to distinguish the outlines of doors and furniture and read short words with a camera mounted on a pair of sunglasses that records everything that is for him before his eyes.

the image path - The camera captures images and sends them to a video processor that Mr. Lane brings to his belt. In turn, the processor converts images into electronic signals to a transmitter that sends also put on the glasses. From here a wireless signal that reaches a receiver implanted in the retina, through which the electrodes stimulates the optic nerve and allows the brain to receive the images.

STUDY WORLD - Peter Lane is just one of 32 people, all over the world, have lent themselves to science to test this technology particularly aimed at care retinitis pigmentosa, genetic disease that causes severe damage to the retina and leads progressively to blindness. Manchester Royal Eye Hospital Lane and two other volunteers underwent a surgery that lasted four hours, during which the electronic receiver implanted in the retina. After two months of waiting, to give the eye time to heal, it's finally time to assess results.

Results - The doctors and their patients, declare themselves very satisfied. All three men have had positive reactions and one of them on November 5 last succeeded, after forty years of darkness, to revise the fireworks. Another, as Peter Lane, is able to read short words. According to the ophthalmologist Paulo Stanga, involved in the research, the results are even better than they expect. The British hospital is developing a special projector and a screen to be installed in the homes of 'installation' to enable them to personally attend to your correspondence, for the first time after so many years. Although the scenario a bit 'to Blade Runner, one should try to imagine what it might mean to go see, even if it is "only" a few words or blurry shadows. In this sense be interpreted the enthusiasm of those who participated in the study: a small first step toward a big ambitious journey.
