A blind man from Minnesota, in the US, has described his joy at seeing his wife for the first time in a decade after doctors fitted him with a "bionic eye" implant.

Video released by the Mayo Clinic showed the delight on Allen Zderad's face as he turned to his wife, Carmen, after he put on the adapted sunglasses that operate with the implant.

"It was the most wonderful moment," said Zderad, 68, a retired chemist who lost his sight to an incurable eye disease.

"I turned to where Carmen was sitting and for the first time in 10 years, I could pick out a shape."

Zderad's new vision is far from normal as he sees only flashes of black and white shapes.

Surgeons at the Mayo Clinic, in Minnesota, embedded an electronic chip in his right eye that receives signals from a camera on the bridge of his sunglasses through a video processing unit, bypassing his damaged retina.
