Science Corporation reported positive preliminary results of a clinical trial examining its Prima retinal implant in patients with central visual field loss due to geographic atrophy.
The PRIMAvera clinical trial included 38 patients with geographic atrophy who underwent implantation of the Prima retinal system. Results showed a “meaningful” improvement in visual acuity, according to a press release.

The system includes a photovoltaic implant that is implanted under the retina, a pair of glasses with a camera and projection system, and a pocket processor that clarifies and magnifies an image, according to the release.
Visual acuity was measured at 6 months and 12 months after implantation using logMAR scoring, with an improvement of 10 letters defined as a success. The mean improvement at 12 months was 23 letters compared with baseline, and the patient with the biggest difference in visual acuity from baseline had an improvement of 59 letters.
The study was designed to show the safety and efficacy of the device to gain a CE mark in Europe, the release said.
“To my knowledge, this is the first time that restoration of the ability to fluently read has ever been definitively shown in blind patients,” Max Hodak, CEO of Science Corporation, said in the release. “This represents an enormous turning point for the field, and we’re incredibly excited to bring this important technology to market over the next few years.”
