Subretinal implant uses light instead of batteries, shows promise in initial testing — Engadget
There’s been significant progress in bringing sight to the blind in recent years, and this looks set to continue that miraculous trend. Scientists at Stanford University have invented a subretinal photodiode implant for people who have lost their vision due to degenerative retinal diseases. Existing tech involves batteries and wires, but the new implant works without such crude appendages. Instead, it’s activated by near-infrared beams projected by a camera that’s mounted on glasses worn by the patient and can record what the patient sees. The beams then stimulate the optic nerve to allow light perception, motion detection and even basic shape awareness. It hasn’t actually been tested with humans just yet, but the first few rodents volunteers have yet to lodge a single complaint.

Bionic Eye Expected To Let The Blind See By 2014 - PSFK
With over 285 million visually impaired people in the world, research into restoring vision for the blind is well past its critical stage. But with innovations in technology, and by turning to a focus to even just restoring rudimentary vision, research suggests that a more expansive solution is on the near horizon. Better yet, it’s a solution that may serve as the foundation for something much more instrumental, for many more people.
A team of electrical engineers at the Monash Vision Group (MVG) of Monash University in Australia has had early success in doing just that. The group has been laboratory testing a new microchip that will be used to power a bionic eye. With pre-clinical assessments due to begin shortly, the team’s encouraging results suggest that the project is on track to deliver a direct-to-brain bionic eye implant ready for patient testing by the year 2014.
