1. A method for fitting a visual prosthesis having a plurality of electrodes, the method comprising:

  • selecting one electrode from among a first electrode and subsequent electrodes as a standard electrode;

    determining a first perceived brightness level on the standard electrode by patient feed back, wherein the first perceived brightness level on the standard electrode is elicited by a first stimulation amplitude;

    approximating the first perceived brightness level on a second electrode by setting a second stimulation level to be applied to the second electrode to the first stimulation amplitude applied on the standard electrode;

    refining the second stimulation amplitude on the second electrode using further patient feedback to elicit the first perceived brightness level on the second electrode; and

    creating and storing a map of brightness to electrode stimulation amplitudes based on the established stimulation amplitudes for the standard electrode and the second electrode,wherein the first and second stimulation amplitudes are provided by a stimulation system.
