One of a number of efforts to restore vision lost to retinal disease, the Boston Retinal Implant Project is working on a wireless prosthesis that minimizes eye intrusion. Only a tiny plate of electrodes is implanted, communicating through radio waves with a larger chip attached to the outside of the eye. This chip gets image data and power from a coil on a pair of glasses.
