All selected candidates for Argus II implantation would preoperatively undergo comprehensive psychological evaluations, a chanel quantitative electroencephalography qEEG with photic stimulation brain mapping for cortical excitability assessment, conventional MRI and related cortical volumetric and morphometric assessments as well as channel optical neuroimaging using our functional near infra-red spectroscopy fNIRS setup. Patients need to be advised that the output from the device would be a whole new type of functional vision rather than restoration of previous vision. A set of various VCF configurations and image processing filters are saved onto the patient's VPU to be applied in different conditions such as normal light conditions, contrast enhancement for low light conditions, and a setting for edge detection.
