Good news for the eye-patients who have gone blind due to retina damage or disease. German scientists have successfully created wireless bionic eyeball recently, which will restore vision of that kind of eye-patients.
It took 12 years of deep research work by the scientists to create this new prosthetic device for the eye-patients. This is named as “bionic eyeball” and it would be fully implanted in the body.
This will bypass the damaged retina; this statement was given by the German scientists from Franuhofer Institute for Microelectronic Circuits and Systems in Duisburg, Germany.
This new system is consisted of implant and external transmitter; both are integrated on the eyeglass-frame.
This integrated implant system plays a key role in this eyeglass-frame and works amazingly. A telemetric link is used to transfer data and energy to this implant system. This received data or image patterns are converted into stimulation signals by this system. These signals are interpretable. The nerve cells of the eye start simulating according to these capture images.
The intact cells are stimulated by 3-D electrodes. This innervating system is present against the retina.
The whole arrangement works perfectly like healthy eyes as long as the optic nerve remains safe without any damage. The vision signals received by the implant system are sent to the brain in a perfect manner like a natural eye system.
Hoc Khiem Trieu, who is working in the Franuhofer Institute, said,
“For normally sighted people that may not seem much, but for the blind, it is a major step”
By the invention of this system the blind people will be able to see like normal sighted people. It would be miracle in medical history. The whole system depends on how the nerve cells are simulated.
Trieu remained involved from the beginning of this project and is one of the major scientists of this discovery. This project was fully financed and supported by the education and research ministry of Germany.
Hoc Khiem Trieu translated the information into an implant and chip design, which was given by the medical experts and material scientists working with him in this project. The whole process was carried out by Hoc Khiem Trieu, who was accompanying with two other scientists, Ingo Krisch and DMichael Goertz.
Dr Krisch talked about this experiment in his statement in the following words,
“A milestone was reached when the prosthetic system finally operated wirelessly and remotely controlled”
As this system was desired to be created any external link; therefore it strongly demanded a thorough research work by these scientists.
This system had to be fitted in the eye; therefore the scientists made the design smaller and used more flexible materials having high performance. This last and final creation was more comfortable to fit in the body.
Goertz describes it as;
“The designs became smaller and smaller, the materials more flexible, more robust and higher in performance, so that the implant now fits comfortably in the eye”
For this great milestone discovery, these scientists are nominated for Joseph von Fraunhofer Prize for 2008 and will be given soon.
