Abstract: A prosthetic vision system is provided with a lens implanted in an ocular socket to focus light onto a coherent fiberoptic bundle. The fiberoptic bundle conveys the received light to photovoltaic semiconductors mounted in a gate array. The gate array is mounted in the region of the calcarine fissure in the user's cortex. The photovoltaic semiconductors stimulate the optic tract or visual cortex much in the manner done in a person having sight.
