Bionic Eye - A Review

Blindness is a devastating disease which can happen due to various reasons such as due to retinitis pigmentosa (RP) and many other age-related macular degenerations (AMD). In this kind of disease, the photoreceptor cells gets degenerated and damages the retina and due to which a person losses his vision power. Therefore, bionic eye plays a vital part by restoring the vision. Technologies that are involved in bionic eyes are-multiple unit artificial retina chip system (MARC), artificial silicon retina system (ASR), ARGUS II, MIT HARVARD device. Holographic technology is used by which a person can again live a new life independently. This method take place through a small surgery replacing complicated surgeries. An advancement in the present research can be done by improving the technology is described in this paper. The quality of images to the bionic eye will be more clear by increasing the number of electrodes in the retinal implant. Platinum and iridium are currently used for implants but these metals deteriorates within 5 to 10 years. Instead of these metals if diamond device are implanted inside the eye then it will not deteriorate.
