Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Retinal stimulation
Alternative stimulus patterns will be tested (vs. baseline). The intervention is the alternative stimulus pattern. The intervention will be tested only in the clinic vs. baseline. The subject will go home with baseline settings. The two alternative stimulus patterns to be tested are asymmetric waveforms and bipolar stimulus.
New visual processing unit (VPU) with asymmetric waveforms
A VPU will apply asymmetric and symmetric stimulation pulses.
New VPU with bipolar stimulation
A VPU will apply bipolar stimulus pulses.
