Abstract
The present invention is an improved retinal electrode array with a remote return electrode outside of the eye. An array of stimulating electrodes is placed on the retinal surface (epiretinally) or under the retina (subretinally) and a large return electrode is placed outside of the sclera and distant from the array of stimulating electrodes. The remote return electrode promotes deeper stimulation of retinal tissue.
