Abstract
The present invention provides a visual prosthesis comprising: image capture means for capturing an image from a surrounding environment; image processing means for processing the image and converting the image into a transmissible image signal; signal processing means for processing and converting the image signal into a stimulation signal; and a retina stimulation device (10) adapted to stimulate the retina of both left and right eyes in accordance with the stimulation signal. The retina stimulation device (10) comprises a left-side stimulation unit (11) having an electrode array (12) for stimulating the retina of the left eye, and a right-side stimulation unit (11′) having an electrode array (12′) for stimulating the retina of the right eye, with the left-side stimulation unit (11) having a configuration which is reversed with respect to a configuration of the right-side stimulation unit (11′). Furthermore, the electrode array (12) has a plurality of individual electrodes (15) distributed in a predetermined pattern across a substrate (16) of the electrode array for stimulating the nerve cells of the retina. The electrode array substrate (16) is elongate in a lateral or transvers…
