  • an external image source producing a video image;

    a micro-cable for conducting the video through a patents eye wall, an electronic chip for demultiplexing the video image into a two-dimensional (2D) array of unit cells;

    a nanochannel glass electrode array hybridized to said 2-D array of unit cells with induim bumps and electrically connecting each unit cell to adjacent neural tissue; and

    an external electronic circuit board generating a biphasic pulse applied globally to the unit cells through the micro-cable causing an electronic signal to be applied to a human eye wherein it is converted to an electrochemical signal transmitted through human tissue within the eye to a patients optic nerve.
