"A man who lost his sight 30 years ago says he can now see flashes of light after being fitted with a bionic eye.

Consultant retinal surgeon Lyndon da Cruz, who carried out Ron's operation said the patients were starting to get meaningful visual stimuli from the technology.

Gregoire Cosendai, of Second Sight, is convinced the technology will prove to be invaluable - but also admits there is still much work to be done."
