## 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.

## Claims
