Retinal Implant Could Restore Functional Sight
From: Medical Design Technology - 04/27/2015

A team led by Stanford University researchers has developed a wireless
retinal implant that they say could restore vision five times better than
existing devices.

Unlike these other devices - which require coils, cables or antennas inside
the eye to deliver power and information to the retinal implant - the
Stanford device uses near-infrared light to transmit images, thereby avoiding
any need for wires and cables, and making the device thin and easily
implantable.
