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 transverse direction, namely in a medial-lateral direction with respect to an implantation orientation, such that the electrode array has a height-to-width ratio of less than 1, preferably less than 0.8, more preferably in the range of 0.6 to 0.2, and most preferably in the range of about 0.5 to about 0.3.La présente invention concerne une prothèse visuelle comprenant un moyen de capture dimages permettant la capture dune image de lenvironnement proche, un moyen de traitement dimages pour le traitement de limage et sa conversion en un signal dimage transmissible, un moyen de traitement des signaux pour le traitement et la conversion du signal dimage en un signal de stimulation et un dispositif de stimulation rétinienne (10) conçu pour stimuler la rétine des deux yeux, droit et gauche, conformément au sig
