Abstract:
1. A visual prosthesis comprising: image capture means for capturing an image from a surrounding environment, wherein the image capture means is configured in the form of a left-side camera and a right-side camera, the two cameras being spaced part from one another at opposite sides of a pair of spectacles; 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 at least one stimulation signal; and a retina stimulation device adapted to stimulate a retina of both left and right eyes in accordance with the at least one stimulation signal; wherein each of a left-side electrode array and a right-side electrode array has an elongated configuration in a lateral or transverse direction such that each of the left-side electrode array and the right-side electrode array has a height-to-width (h/w) of less than 0.8, and wherein the retina stimulation device comprises left-side stimulation unit and the right-side stimulation unit which comprise an elongate connection for conducting or conveying the at least one stimulation signal to electrodes of the respective electrode arrays, and wherein the elongate connection respectively extends to and/or from the respective electrode array at a predefined angle (θ) of between 0° and 90°, or between 20° and 70°, relative to a lateral or transverse direction (P) with respect to an implantation orientation of the electrode array, the elongate connections being configured for being arranged in a predefined angled configuration, and mirror-imaged.
