applicant has proposed a combination of the subretinal and epiretinal methods by placing the electronics external to the eye , entering the eye through the pars plana and the piercing the retina from inside the eye to stimulate subreintally . the present invention is an improved electrode array for subretinal stimulation . a hard polymer such as polyimide is biocompatible and strong for supporting an electrode array and supporting traces in a thin flex circuit array . in the present invention applicant takes advantage of the sharp nature of thin polyimide making a point on the end of the electrode array . this allows the flexible circuit electrode array to be both electrode array and surgical tool to cut the retinal and slide the array under the retina in a single action .
