1 The Bionic Eye Department of Electrical, Computer, and Biomedical Engineering – BME 181 Andrew Rosenberg

2 Healthy Vision 1.Reflected light enters the cornea (Window of the eye) 2.Light travels through the pupil -Contracts or dilates depending on how brightness of surroundings 3.Light enters the lens -Just like a camera, the lens of the eye focuses light 4. The light beams through the center of the eye to the retina 5.Retina: -Photoreceptors (Specialized cells that convert light into electric impulses) -Macula (Center of the retina that contains more photoreceptors than any other part of eye)

3 Reasons for Bionic Eye Macular Degeneration Retinitis Pigmentosa -Age Related -Loss of central vision and blurred peripheral vision -Macula deteriorates over time -Vision becomes gray -10% of adults over age 55 world-wide -Genetic -Loss of peripheral vision inward -Photoreceptors in periphery deteriorate -1.5 million people world-wide

4 Components (The Argus®II) Internal Parts External Parts

5 Eligibility, Procedure, and Cost -Must have Retinitis Pigmentosa *Newer models will work with Macular Degeneration -Showing later symptoms of disease -2 to 5 hour surgical procedure for internal parts -Small incision, minimal scarring, and uncomplicated -Return to hospital for external fitting and programming -Training and therapy -Patients must learn to recognize objects with bionic eye -$115,000 in Europe before surgery -$150,000 in U.S.A. before surgery -Insurance companies will help more as the technology improves

6 Benefits & Future Outlook -Partial restoration of vision -Gain more independence -Able to view objects on a larger scale -Upgradable software -If newer technology is released further surgery is unnecessary 1.Argus®I (Prototype) -16 pixels of resolution -15 seconds to recognize an object 2.Argus®II (On the Market) -60 pixels of resolution -2 to 3 seconds to recognize an object 3.Argus®III (In Progress) -200 pixels of resolution -Recognition time unavailable
