1. A method for fitting a visual prosthesis having a plurality of electrodes, the method comprising:
- determining at least one level on a first electrode by patient feed back;
determining at least one other level for subsequent electrodes based on previous results and further patient feedback; and
creating and storing a map of brightness to electrode stimulation levels based on the established levels.

Abstract
Methods and devices for fitting a visual prosthesis are described. In one of the methods, threshold levels and maximum levels for the electrodes of the prosthesis are determined and a map of brightness to electrode stimulation levels is later formed. A fitting system for a visual prosthesis is also discussed, together with a computer-operated system having a graphical user interface showing visual prosthesis diagnostic screens and visual prosthesis configuration screens.
