Abstract
A visual prosthesis system comprises a retina implant at least partly located in the interior of a patient's eye. The retina implant comprises an array of micro-contacts adapted for contacting ganglia of the patient's retinal tissue. The visual prosthesis system further comprises a data processing unit with an additional interface for receiving an external signal from an external signal source, the data processing unit being adapted for converting the external signal into corresponding stimulation data for the retina implant, and a wireless transmission unit adapted for transmitting the stimulation data to the retina implant via wireless transmission. The retina implant is adapted for receiving the stimulation data and for stimulating the micro-contacts according to the stimulation data.
