Retinal prostheses - Bionic eyes


"Evolution is the secret to next step"

                                             - Karl Lagerfeld

As this quote says, evolution is inevitable. Over these years humans evolved in a way that no one in the past would have believed. Technological advancements play a key role in human evolution. Twenty years back, no one would have believed that we attend our classes and work in virtual mode. Now it's happening. 

The technological advancements directly made its impact in the field of medicine and its allied sectors too. A major technological marvel which will bring vision back to the visually challenged people is now available which is nothing but, "Bionic eyes".

Now in this blogger we tried to cover about the bionic eyes.

Let's start.

After lots of research for almost a decade scientist from Monash university, Australia finally invented this marvel.

 How to implant the bionic eyes:

Without wasting time lets dive into it.

What is Retinal prostheses:

The retinal prosthesis is nothing but the restoration of the vision for those who are having degeneration in their retina.

What are Bionic eyes:

The bionic eyes are nothing but a combination of the microelectrode and the camera built in glasses and the sequence of events between them bring out the vision to the visually impaired individuals.

Who are all get benefitted by the bionic eyes:

Those who have the destitution in the vision especially those who are all having the retinal problem able to get vision by this bionic eye.

Retina and functions of retina:

Retina is a thin layer of nervous tissues inside the eyes the main function of the retina is that it perceives the light and convert it to neural signals to the brain and thus aids in the vision.



Is it possible to replace the damaged retina:

As of now the answer is "Definitely not"

Once the retina gets damaged it won’t be replaced. but the invention of the bionic eye would be the perfect thing for those who are all having retinal impairments in the eyes.

Components of bionic eye:

  • Micro electrode
  • Glasses for the vision with built in camera

Action performed by the components:

   The micro electrode is placed inside the eyes with a system of complex surgery. Why the electrode is actually placed inside the eyes means that the micro electrode takes over the function of the diseased cells (damaged cells) in the eyes.

The micro electrode transmits the impulse (signal) to the camera that is attached on the glasses and thus the affected person perceives the vision (Which is actually a function of retina)

This is a boon to those who are all having complete impairments in their eyes especially on retina. 

Like having two sides to a coin the implantation of the bionic eyes having its own disadvantages too

  • Though the bionic eye implanted individuals can’t able to get 100% vision (but after the retinal prostheses the person could able to see things to an extent)
  • This bionic eyes technology is only at the initial stage and it needs to be tamed in the forthcoming days.
Cost of bionic eyes implantation:
  • In some countries like India the cost of the bionic eye implantation (the retinal detachment surgery) is expected to be nearly around 50,000 USD (22lakh Indian rupees approximately) and additional charges for the surgery. This couldn’t be affordable for all.
  • Some practical difficulties include less specialized medical facilities.

Hope that  governments, doctors, medical insurance companies all over the world came forward to develop the retinal prostheses to next level and thus ensures the people to live a healthy and prosperous life.

Today’s English word,

Typhlosis 

This means Inability to see.

Sentence usage

The invention of the bionic eye is a boon to those having typhlosis.
