BIONIC EYE

Bionic eye is an Artificial electronic eye.The electronic device which replaces functionality of a part or whole of the eye.The main purpose of bionic eye is to provide vision.The implant is a small chip that is surgically implanted behind the retina in the eye ball.There are two basic methods of bionic eyeMARC( Multiple Unit Artificial Retina Chip )ASR ( Artificial Silicon Retina system)

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. 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. WHAT IS BIONIC EYE
Bionic eye is an Artificial electronic eye.
The electronic device which replaces functionality of a part or whole
of the eye.
The main purpose of bionic eye is to provide vision.
The implant is a small chip that is surgically implanted behind the
retina in the eye ball.
There are two basic methods of bionic eye

14. ADVANTAGE
Compact size- 6*6 mm
Diagnostic Compatablity
Reduction of stress upon retina
Very early in the visual pathway
No batteries implanted with in body
power requirement – 1\4 of milli watt

15. DIS ADVANTAGE
Costly.
If a single part of the chip is damaged the total technique will be
meaningless.
Providing power to run bionic implants and making
connections to the brain’s control system poses the great
challenges for biomedical engineers.
Extra circuitry required for downstream electrical input.

16. CONCLUSION
The implant is very expensive.
Bionic devices are being developed to do more than replace
defective parts.

Researchers are also using them to fight illness.
We are now looking at devices like bionic arms ,tongues ,nose
etc..
