1. A visual prosthesis comprising:
- a video receiver for receiving a video image and converting said video image to a video signal;
a video processing unit, coupled to said video receiver and processing said video signal;
within a housing suitable to place external to a human body;
a manually operable user interface on said housing, accepting user input and controlling said video processing unit and, thereby, electrode signal parameters; and
a plurality of electrodes driven in accordance with said video signal and said electrode signal parameters, stimulating visual neurons to create a perception of said video image.

Abstract
The present invention is a visual prosthesis for the restoration of sight in patients with lost or degraded visual function. The visual prosthesis includes a user interface which controls function of the visual prosthesis to optimize operation for each individual patient. The user interface controls functions such as brightness, contrast, magnification, frequency, pulse width, or amplitude. The user interface may also individually control points of neural stimulation.
