Bionic Vision: A Solution To The Visually Impaired

Scientific Research

Eyesight is the most beautiful gift a living species can have and devoid of it anyone would face many problems. There are many visually impaired and blind people in the world and medical science is still in the search for that perfect way to stop the impairments.  In the past decade or so, there have been many concepts that came from within the medical field and from enthusiastic inventors to encounter the problems with vision. One of the concepts is to manipulate the genes of an individual stimulating the growth of new cells enabling vision.

A company named Second Sight, situated in California; USA has done wonderful research and experimentation to ensure that vision impairment does not become a barrier for an individual to see the world or live in it normally. The company is already manufacturing a device that can be implanted on the retina and uses the existing retinal cells to stimulate the cortex of the eye. However, this involves the placement of the device on the top of retina, which may not be possible all the time.

Now, the research is proving successful for a Cortical Prosthesis method, where the device is implanted to the eye. It would create no irritation or novel sensation after a few days. The device name Orion I will act as a wireless visual cortical stimulator. The device consists of an electrode array, electronic case and an antenna. The bionic vision device would be placed into the visual cortex so that it can perform neuro-stimulation without the use of wires. The electric surge required for the device is produced from the brain and the Orion I would act as a part of the eye. Fascinatingly, it helps the patient through the electrode array to comprehend light.  By doing so, an individual can see the objects before him/her and have vision like a normal human being.

Although, this is an invasive method researchers have found no side effects of the bionic device. In addition, the device was able to let an individual with visual impairment see. On a large scale, this device could prove fruitful to tackle the problems of vision across the globe.
