WORLD'S FIRST BIONIC EYE TO GIVE MILLIONS THE CHANCE OF SEEING AGAIN



Bionic eye can give a millions of people a chance of seeing again. The experiment on implementing bionic eye to the blind patient was successful. Based on the research, it stated that the patient who undergoes the operation had suffered blindness for eight years ago due to the rare disease called Vogt-Koyanagi (VKH) syndrome. Walton (2016) defined this Vogt-Koyanagi (VKH) syndrome as “a multisystematic disorder characterized by granulomataous panuveities with exudative retinal detachments that is often associated with neurologic and cutaneous manifestations”. This rare disease is attacking the pigments in the eyes. Within a year suffered in the disease she started to lose her sight and she was completely blind. According to Spencer (2016), a medical correspondent for the Daily Mail stated that “…surgeons have implanted a visual stimulator chip in the brain of a 30-year-old-woman. The patient, who has totally blind for seven years, saw colored flashes, lines and spots when signals were sent to her brain from a computer.

The diagram shows how the new bionic eye would work, sending signals directly to the brain. The computer sends signals to the antenna, which connected to the brain.

Dr. Nader Pouration who performed the surgery is planning to send footage from a tiny video camera to the brain, which could provide the world’s first bionic eye and restore sight to a millions. Spencer also stated, “During six weeks of testing, the patient has consistently seen the exact signals the scientists sent to her visual cortex, the section of the brain which usually receives images from the optic nerve”. Dr Pouratian inserted the stimulator which is an array of tiny electrodes into the back of her brain in August. Within the four-hour procedure, surgeons will cut a small hole in the back of her skull and laid the stimulator on the surface of her brain. A small antenna receiver was implanted into the gap in her skull, which receives signals sent from a computer. The doctors then will wait for a permission from US regulator to connect the system called ‘Orion I’  to a camera worn in a pair of glasses, which they hope will send moving images directly to the brain.


The process of restoring the sight to the patient

Scientists are on the brink of restoring sight to the blind by sending moving images directly to the brain. This technology has the potential to restore sight for the millions of people who have lost their sight or becoming blinded by cancer. Thus, it is proven that this implemented of bionic eye to the human is actually works wonder because this system has the potential to restore sight to the blind.
