Four Australians gave bionic eyesight



Four blind Australians renewed their eyes after implanting bionic eyes.

Before the study began, patients who had lost vision due to retinal pigment degeneration sensed light and darkness but did not see a waving hand in front of them.

Bionic Vision Technologies says patients can now distinguish objects in pixel in grayscale, which allows them to navigate without guide dogs, walking sticks or family members.

Chief scientist Professor Associate Professor Penny Allen says this technology can be a breakthrough for thousands of Australians affected by Retinitis Pigmentosa because there is no way to delay or cure a genetic condition.

"This is now a very important cause of blindness in working age, our patients are between 30 and 60 years old," said AAP.

"We are very happy with how they develop and are really happy, and that's the best of all."

Prof. Allen, who is the principal surgeon at the Center of Eye Research Australia, will present on Monday an annual research at the annual meeting of scientists from the Royal Australian and New Zealand College of Ophthalmologists in Adelaide.

While other bionic eyes appeared on the market abroad, Professor Allen said that Australian technology is simpler and safer while scientists have developed their own vision processing software.

The bionic eye works by capturing images with a camera connected to the glasses and transmitting them to an external processor carried in a purse or attached to a belt.

The information is then sent back to the device magnetically attached to the scalp of the patient, which is connected through the cable to the implanted device in the eyes and then processed by the brain.

After next operations, the next phase of research began, as participants transfer technology from the laboratory to the home.

First of all, they had to undergo training with obstacles and other tests, learning to "trust" what they see after years of lack of vision, said prof. Allen.

"We work with them to identify the things they want to do at home, the normal tasks that we all do.

"One patient sorts the laundry, the colors from whites, and one patient wants to be able to move around on some things in the yard, such as a lemon tree."
