1. A retinal prosthesis comprising:
- an electrode array suitable to be mounted in close proximity to a retina inside the sclera;
a demultiplexer electrically coupled to said electrode array , the demultiplexer suitable to be mounted inside the sclera;
an electronics package, including a multiplexer within, electrically coupled to said demultiplexer via a single cable, the electronics package suitable to be mounted outside the sclera;
wherein, during the operation of the retinal prosthesis, the demultiplexer is located inside the sclera, the electronics package including the multiplexer is located outside the sclera, and the single cable piercing the sclera.

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.
