German Implant Research 

German researchers are continuing work on a retinal implant, according to English-language site Deutsche Welle:


... researchers at the RWTH Aachen University of Technology developed a special device for sufferers of retinitis pigmentosa. The prosthetic consists of two parts: a high-tech pair of glasses and an implant that is surgically placed in the eye.

A tiny video camera is built into the glasses, along with an encoder that converts images into signals the nerves understand. The signals are then sent wirelessly to a receiver that has been implanted into the ocular lens.

The signals are then transferred to a micro contact film via a miniscule cable. These lie directly on the retina and stimulate with electrodes the nerve cells that lead to the optic nerve.

The article says that the implants are being tested on animals and gives information about other research into retinal implants.
