Device Function
During the clinical trial, most subjects experienced
changes in the number of electrodes that were
programmed in the VPU. As of March 2012, this
number ranged from as few as 8 electrodes in
some subjects to as many as 60 electrodes in
other subjects. The average number of electrodes
programmed for stimulation in the VPU was 38.
The stimulation limit was lower for home use than
for clinical testing. Because of this, some
electrodes that were programmed for stimulation
in the VPU were not able to independently
produce light perception during home use. As of
March 2012, the number of electrodes that
produced light perception when they were
stimulated one-at-a-time at the lower home use
