Abstract

Three critical improvements resulting from computer simulations for present day and future retinal vision implants are proposed and discussed: (1) A time profile for the stimulation current that leads predominantly to transversal stimulation of nerve cells; (2) auxiliary electric currents for electric field shaping with a time profile chosen such that these currents have small probability to cause stimulation; and (3) a local area scanning procedure that results in high pixel density for image/percept formation, except for losses at the boundary of an electrode array.
