For example, Age-Related Macular Degeneration (ARMD) is a progressive disease of the retina wherein the light-sensing cells in the central area of vision (the macula) stop working and eventually die Ref [1]. By replacing the dead parFor the last decade, groups of cell biologists, chemists and physicists all over the world have been focusing their motivation of research for the improvement of human life. Biological backgrounds interpreted with the chemical understandings of a living cell have led physicists to fabricate “Intelligent Devices” sensing alternative to those organs which are naturally integrated in the human body.

Broadly speaking these built-in or integrated organs (eye, nose, skin, ear, tong, heart, lungs, etc) in the human body are the devices which provide a man “a signal” of an image, touch, taste, hearing, smell. These impulsive signals are then transmitted through the tissue to the respective part of the central processing unit, the brain. The theme of the today’s research is to imply this simple natural process, design and fabricate a substitute to these sensors when the built-in sensor does not work for certain reasons. These substituted devices are called Implants. An example of such an implant is the Retinal Implant.

An eye is a precious part of a human which plays an integral sensory role for the visual capability of the vision. Because of many factors this part may come to loose its visionary sensing power in some human beings.

By replacing the dead part of retina with the retinal implants, theoretically and practically, the diseases related with retina can hopefully be controlled.

The principle and working of an Eye

The construction of the Eye is similar to that of a camera. In principle, the visible light is focused by a lens on a screen called the retina and the image is realized. Fig.1 (please find at http://webvision.med.utah.edu/sretina.html) shows a cross-section of human eye ball with its different parts. The Retina, being the most significant in the functioning of the eye, is composed of layers with different cells as shown in Fig. 2 (please find at http://www.farlops.com/images/photos/retina.jpg ) The light first enters the Nerve Fiber Layer and the Ganglion Cell Layer, under which most of the nourishing and aiding blood vessels of the retina are located. This is where the nerve begins, picking up the impulses of the acquired image from the retina and transmitting them to the brain. The light is received by the Photoreceptor cells called Rods and the Cones. These cells convert light into nerve impulses, which are then processed by the retina and sent though nerve fibers to the brain. The nerve fibers exit the eyeball
