Breakthrough Retinal Implant Restores Vision in Patients with Advanced Macular Degeneration

Science Corp.'s PRIMA retinal implant system has achieved a significant milestone in the treatment of age-related macular degeneration (AMD), offering new hope for millions suffering from this debilitating eye condition. A recent study published in The New England Journal of Medicine demonstrates remarkable improvements in vision for patients with geographic atrophy, an advanced form of AMD.

Clinical Trial Results Show Promising Outcomes

The groundbreaking study, led by Dr. Frank Holz, Chair of the Ophthalmology Department at the University of Bonn, evaluated 32 patients who received the PRIMA implant. After one year, 27 patients showed significant improvement in their ability to read letters, numbers, and words. Moreover, 26 patients experienced a substantial increase in visual acuity, with an average gain of more than five lines on a standard eye chart.

Dr. José-Alain Sahel, a co-author of the study and professor of ophthalmology at the University of Pittsburgh and Sorbonne University, emphasized the unprecedented nature of these results. "This marks the first time that an attempt at vision restoration in these cases has achieved results – and in such a large number of patients," he stated. Some patients have even regained the ability to read pages in a book, a feat previously thought impossible for those with advanced AMD.

Innovative Technology Behind PRIMA

The PRIMA system, developed based on research by Stanford University professor Daniel Palanker, Ph.D., combines a miniature wireless chip with specially designed glasses equipped with a camera. This brain-computer interface technology works by projecting near-infrared light onto the implant, which then stimulates remaining retinal cells to transmit visual signals to the brain.

While the current version of PRIMA provides only black-and-white vision with relatively low resolution, it represents a significant advancement in treating late-stage AMD. The system includes a "zoom-in" feature, allowing patients to magnify letters for improved readability. Science Corp. is already working on the next iteration of the device, aiming to enhance visual performance through digital image processing and improved ergonomics.

Regulatory Outlook and Future Availability

Following these promising results, Science Corp. has filed for regulatory approval in Europe and is pursuing approval from the U.S. Food and Drug Administration (FDA). The company anticipates making the PRIMA system available to patients in Europe as early as next year, potentially revolutionizing treatment options for those with advanced AMD.

As the global population ages, the number of individuals affected by AMD is expected to rise, making this breakthrough particularly timely. The PRIMA system offers a paradigm shift in AMD treatment, actively restoring lost vision rather than merely slowing disease progression like current therapies.
