A revolutionary eye implant is helping blind people to see again in what doctors are calling a “life-changing” breakthrough.

The PRIMA system, developed by scientists in London, allows patients who have lost their vision due to age-related macular degeneration (AMD) to read and recognise shapes once more.

The tiny electronic chip, measuring just 2mm by 2mm and half the thickness of a human hair, is fitted beneath the retina — the light-sensitive layer at the back of the eye. It works by restoring vision in people who have geographic atrophy (GA), an advanced form of AMD that affects around five million people worldwide and is responsible for one in four cases of legal blindness in the UK.

Dr. Mahi Muqit, senior vitreoretinal consultant at Moorfields Eye Hospital, explained that the results have been astonishing.

He said: “I have all these patients who are blind, and when you see them, they want to know if there’s anything that can restore vision. The answer has always been no. We’ve got some patients who are now reading books — their quality of life is much higher.”
