We claim:

1. A visual prosthesis comprising: an external communication unit receiving operational data; an internal communication unit transmitting said operational data; and a plurality of electrodes driven by said internal communication unit and stimulating visual neurons to create a perception of a visual image.

2. The visual prosthesis according to claim 1, wherein said operational data includes current.

3. The visual prosthesis according to claim 2, wherein said current is electrode current.

4. The visual prosthesis according to claim 1, wherein said operational data includes electrode impedance.

5. The visual prosthesis according to claim 1, wherein said operational data includes voltage.

6. The visual prosthesis according to claim 5, wherein said voltage is electrode voltage.

7. The visual prosthesis according to claim 1, wherein said operational data includes whether or not a predetermined compliance voltage has been reached.

8. The visual prosthesis according to claim 1, wherein said operational data includes electrical recording from visual neurons.

9. The visual prosthesis according to claim 1, wherein said operational data includes an indication of power received by said internal communications unit.

10. A visual prosthesis comprising: an external communication unit receiving operational data; an internal communication unit transmitting said operational data; and a plurality of electrodes driven by said internal communication unit and stimulating a retina to create a perception of a visual image.

11. The visual prosthesis according to claim 10, wherein said operational data includes current.

12. The visual prosthesis according to claim 11, wherein said current is electrode current.

13. The visual prosthesis according to claim 10, wherein said operational data includes electrode impedance.

14. The visual prosthesis according to claim 10, wherein said operational data includes voltage.

15. The visual prosthesis according to claim 14, wherein said voltage is electrode voltage.

16. The visual prosthesis according to claim 11, wherein said operational data includes whether or not a predetermined compliance voltage has been reached.

17. The visual prosthesis according to claim 10, wherein said operational data includes electrical recording from the retina.

18. The visual prosthesis according to claim 10, wherein said operational data includes an indication of power received by said internal communications unit.

19. A visual prosthesis comprising: video receiver for receiving a video image and converting said video image to a video signal; and a video processing unit, coupled to said video receiver and processing said video signal; an external communications unit transmitting said video signal and receiving operational data; an internal communications unit transmitting said operational data and receiving said video signal. a plurality of electrodes driven by said internal communications unit and stimulating visual neurons to create a perception of said video image.

20. The visual prosthesis according to claim 19, wherein said plurality of electrodes stimulate visual neurons on a retina.

21. The visual prosthesis according to claim 19, wherein said operational data includes current.

22. The visual prosthesis according to claim 21, wherein said current is electrode current.

23. The visual prosthesis according to claim 19, wherein said operational data includes electrode impedance.

24. The visual prosthesis according to claim 19, wherein said operational data includes voltage.

25. The visual prosthesis according to claim 24, wherein said voltage is electrode voltage.

26. The visual prosthesis according to claim 21, wherein said operational data includes whether or not a predetermined compliance voltage has been reached.

27. The visual prosthesis according to claim 21, wherein said operational data includes electrical recording from visual neurons.

28. The visual prosthesis according to claim 21, wherein said operational data includes an indication of power received by said internal communications unit.

29. A method of restoring vision in a patient with impaired vision comprising the steps of: receiving a video image; converting said video image to a video signal suitable for stimulation of visual neurons; transmitting said video signal into the patient; stimulating visual neurons in accordance with said video signal; and transmitting operational data out of the patient.

30. The method according to claim 29, further comprising the steps of recording neural activity and transmitting said neural activity as part of said operational data.

31. The method according to claim 29, further comprising the steps of measuring the state of individual electrodes and transmitting electrode measurements as part of said operational data.

32. The method according to claim 29, further comprising the steps of measuring power received inside the patient and transmitting said power received inside the patient with said operational data.
