Retinal prosthesis with separate central electrode array and peripheral electrode array
While a photolithographed array internal to the retina provides superior resolution, an array external to the retina provides easier implantation and improved manufacturability. Therefore it is advantageous to supply a high-resolution electrode array internal to the sclera, near the fovea and a lower-resolution electrode array eternal to the sclera near the periphery of the retina.Even if a separate lower-resolution array is implanted internal to the sclera, super-choroidal (between the choroid and sclera) or intra-scleral (between the layers of the sclera), it is easier to make a lower-resolution array in a curved shape.
