A bionic eye has given an Australian woman partial sight and researchers say it is an important step towards eventually helping visually impaired people get around independently.

Dianne Ashworth, who has severe vision loss due to the inherited condition retinitis pigmentosa, was fitted with a prototype bionic eye in May at the Royal Victorian Eye and Ear Hospital.

"It was really funny when it switched on I was waiting, waiting … I had these goggles on and I didn’t know what to expect, and I don’t know if anyone did know what I was going to see … Then all of a sudden I went ‘yep’ I could see a little flash and it was like a little, I suppose, a splinter … There were different shapes and dark black, lines of dark black and white lines together … Then that turned into splotches of black with white around them and cloud-like images … I can remember when the first bigger image came I just went ‘Wow,’ because I just didn’t expect it at all but it was amazing," she said.

The bionic eye, designed, built and tested by the Bionic Vision Australia, a consortium of researchers partially funded by the Australian government, is equipped with 24 electrodes with a small wire that extends from the back of the eye to a receptor attached behind the ear.

Britain’s first bionic veteran has a new brain-controlled robotic arm that is transforming his life.

Andrew Garthwaite, 25, had his right arm blown clean off by a rocket-propelled grenade during a firefight with the Taliban in Afghanistan in September 2010. In January he had the state-of-the-art limb wired to his nervous system during a six-hour operation in Vienna, Austria.

Now he is getting to grips with his new body part and is able to ride his motorcycle and drive a car again. Mr Gathwaite, who lives with his new wife Kailey, also 25, in South Shields, Tyneside, said:

'It's been incredible. I thought I might never be the same. But my life is starting to get back to normal - I'm on my motorbike and I'm back in a car. I can do things that I never thought I would have been able to do'.
