Revolutionary Solar-Powered Retinal Implant Enables Blind Patients to Read Again

Major Vision Restoration Breakthrough

A revolutionary electronic eye implant has reportedly restored reading vision to people blinded by dry age-related macular degeneration, according to a major European clinical trial. Sources indicate that patients using the PRIMA implant combined with augmented-reality glasses were able to see letters and words again after years of vision loss.

Clinical Trial Results

The study, published in The New England Journal of Medicine, revealed that 84% of participants were able to recognize letters, numbers, and words using prosthetic vision in eyes that had previously gone blind. Analysts suggest these findings represent a significant advancement in treating geographic atrophy, the advanced form of dry AMD that currently has no approved treatment.

The clinical trial involved 38 participants across 17 hospitals in five European countries, with Moorfields Eye Hospital serving as the only UK site. According to reports, participants treated with the implant were able to read five lines of a standard vision chart on average, whereas some couldn’t see the chart at all before the procedure.

How the PRIMA System Works

The PRIMA implant represents a novel approach to artificial vision, according to researchers. The system consists of three main components:

A wireless subretinal photovoltaic implant that acts like a miniature solar panel, measuring just 2mm x 2mm and 30 micrometers thick
Specialized augmented-reality glasses with a video camera that captures visual information
A waist-worn computer with artificial intelligence algorithms that process visual data

The report states that the surgical procedure involves inserting the wafer-thin microchip beneath the central retina through a small opening. After surgery, the glasses project visual scenes as an infrared beam directly onto the chip, which then converts the information into electrical signals transmitted to the brain.

Patient Experience and Rehabilitation

Sheila Irvine, one of the trial participants from Moorfields, described her experience: “Before receiving the implant, it was like having two black discs in my eyes. I was an avid bookworm, and I wanted that back.” She noted that learning to read again wasn’t simple but became easier with practice., according to recent research

Patients reportedly undergo intensive rehabilitation over several months to learn to interpret the new visual signals. The system includes a zoom feature that allows patients to magnify letters, and no significant decline in existing peripheral vision was observed in trial participants., according to industry reports

Medical Significance and Future Applications

Mr. Mahi Muqit, associate professor at the UCL Institute of Ophthalmology and senior vitreoretinal consultant at Moorfields Eye Hospital, who led the UK arm of the study, stated: “In the history of artificial vision, this represents a new era. Blind patients are actually able to have meaningful central vision restoration, which has never been done before.”

He added that the procedure can be performed by any trained vitreoretinal surgeon in under two hours, which analysts suggest could make the treatment widely accessible. The researchers indicate that this technology could potentially be used to treat multiple eye conditions beyond macular degeneration in the future.

Global Impact and Next Steps

The global trial was led by Dr. Frank Holz of the University of Bonn, with participants from the UK, France, Italy, and the Netherlands. The PRIMA System device is being developed by Science Corporation, which specializes in brain-computer interfaces and neural engineering.

These findings reportedly pave the way for seeking regulatory approval to market the device, potentially offering hope to the estimated 5 million people worldwide affected by geographic atrophy. The successful restoration of reading ability represents a major improvement in quality of life for patients suffering from advanced vision impairment.
