Abstract
A retinal implant device to stimulate a retina of an eye thereby producing a specific effect in an eye, such as vision or drug treatment of a chronic condition is described. The retinal device is made of a retinal implant that is positioned subretinally and that contains a multitude of stimulation sites that are in contact with the retina. A connection carries the stimulating electrical signal or drug. The connection passes transretinally through the retina and into the vitreous cavity of the eye, thereby minimizing damage to the nutrient-rich choroid. The lead is attached to a source of drugs or electrical energy, which is located outside the eye. The lead passes through the sclera at a point near the front of the eye to avoid damage to the retina.
