A Light-Powered Retina Implant For the Blind
the_newsbeagle writes: In certain diseases of the retina, people lose function in the photoreceptor cells that respond to light and trigger a message to the brain. So engineers have designed various retina implants that do the job instead, including the Argus II system, which received the first FDA approval for an implanted visual prosthetic in 2013. But the Argus II only produces vision of about 20/1200. A new implant in the pipeline from Stanford University has already achieved 20/250 vision in rats, and is aiming at 20/120, which would be below the legal threshold for blindness. This implant is photovoltaic, so the same infrared light that beams an image of the world into the implanted chip also powers its electronics. -
The Blind Shall See Again, But When?
An anonymous reader writes "Restoring hearing with cochlea implants that replace the inner ear with an electronic version has become standard procedure for many types of deafness. Now it looks like the same thing might happen for many types of blindness. With five national labs funded by the Department of Energy, this third-generation artificial retina promises to enable the blind to see again soon. Already it has been successful in over a dozen test patients, but at resolutions too low for doing much more than proving the concept. However, if the DoE can perfect this larger version of an artificial retina, then the company Second Sight promises to commercialize the implant, aiming for VGA resolution within the decade."
