Patent ID: 7962221

Claim:
A method for providing artificial sight to a patient, comprising: generating an original image; processing the original image to generate a processed image; generating a first stimulation current based on the processed image; providing a first stimulation to a retina of the patient using the first stimulation current; perceiving a first perceived image produced by the first stimulation, wherein the first perceived image is a spatially distorted image of said original image, determining a spatial distortion between the original image and the first perceived image; generating a second stimulation current; providing a second stimulation to the retina of the patient using the second stimulation current; and perceiving a second perceived image produced by the second stimulation the second perceived image being representative of said original image, wherein spatial distortion of the second perceived image is lower than spatial distortion of said first perceived image and wherein a stimulation difference between said first stimulation and said second stimulation corresponds to an adjustment of the determined spatial distortion.
