Abstract
A retinal prosthesis with an improved configuration by mounting necessary components within and surrounding the eye. The improved configuration better allows for the implantation of electronics within the delicate eye structure and further limits the necessary width of a thin film conductor passing through the sclera by use of a multiplexer external to the sclera and a demultiplexer internal to the sclera.
