ARTFICIAL EYE
- 1. ARTIFICAL EYE PRESENTED BY: MUHAMMAD HAMZA KHAILD
- 3. INTRODUCTION: • About 285 million people are visually impaired worldwide: 39 million are blind and 246 million have low vision (severe or moderate visual impairment) • There are 10 million people in the US who are blind or facing blindness due to disease of the retina…. and there’s little that can be done for them. • The U.S. Food and Drug Administration (FDA) has granted market approval to an artificial retina technology, the first bionic eye to be approved for patient in the U.S.
- 4. WHAT IS ARTIFICAL EYE? • An ocular prosthesis (artificial eye) is a type of craniofacial prosthesis that replaces an absence of natural eye following an enucleation, evisceration, or orbital exenteration. • The prothesis fits over an orbital implant and under the eyelids.
- 5. HOW EYES WORK? • The light coming from an object enters the eye through cornea and pupil. • The eye lens converges these light rays to form a real, inverted and diminished image on the retina. • The light sensitive cells of the retina get activated with the incidence of light and generate electric signals.
- 6. HOW BRAIN WORKS AFTER SEEING IMAGE? • After seeing an image the brain takes information from the outside world and encodes it in patterns of electrical activity • After the creating pattern the brain get an visualization of an image. That can we actually seeing the image from our eyes.
- 9. ARGUS-II DEVICE • (“Argus II”) is the world’s first approved device intended to restore some functional vision for people suffering from blindness. • Transmits images from a small, eye-glass- mounted camera wirelessly to a microelectrode array implanted on a patient’s damaged retina.
- 10. PARTS OF ARGUS-II DEVICE: • A small electronic device implanted in and around the eye. • A tiny video camera attached to a pair of glasses, and a video processing unit that is worn or carried by the patient.
- 11. HOW IT WORKS?
- 12. HOW IT WORKS? • The patient wears glasses with an attached video camera that captures images of the surrounding area.
- 14. ADVANTAGES: • Ability to perform visual tasks demonstrated in many patients. • Upgradable external hardware and software to benefit from future innovations • The brain has an amazing ability to adapt to new input and to improve his or her understanding of what is being “seen” via an artificial vision system
- 15. DISADVANTAGES: • The cost of device is too high($1500). • It is difficult to acquire this technology common man.
- 16. CONCLUSION: • People suffering from low version too, people who are completely blind will benefit from this project. • This technology used by U.S and economic Europe countries.
