Artificial Eye - Nano Retina
Retinal Degenerative Diseases
The most common retinal degenerative disease is the damage of photoreceptor cells of the retina. Photoreceptor cells are light sensing cells of the retina, a delicate layer of nerves at the back of the eye. These cells receives light signals and relays the message to the brain and reflects an image to the brain. When the photoreceptor degenerates, images could be blurred or even unable to display. This is often a progressive disease and Nano Retina could help process the image or even
"[s]timulate photoreceptor function by mimicking the inner retinal nerve cells, which in turn pass the signal through the optic nerve to the brain, thus restoring visual perception." (AE4).
Surgical Implant of Nano Retina
A surgery implantation of the nano retina is a relatively easy surgery that can restore one's vision fully. The whole surgical procedure usually takes less than an hour and it can be done in an ambulatory environment without hospitalization. Additionally, there is no need to add a wiring outside the eye resulting in a low risk surgery and a faster recovery time.
A video to better understanding the surgical implant of Nano Retina
The whole surgical procedure is basically cutting open a small part of the top of the eye and inserting the microchip at the back of the eye. Additionally, a pair of rechargeable glasses specially designed for this implantation is needed to reflect light into the microchip so as to reflect images and relay messages to the brain to enable patients to see again.
