Age-related macular degeneration (AMD) is a degenerative disease that causes a progressive loss of central vision.
The vision loss is concentrated in the macula, the central area of the retina responsible for high-detail vision for tasks like face recognition or reading. AMD is commonly classified into dry AMD caused by a thinning of the retina as photoreceptors degenerate or wet AMD caused by abnormal blood vessels in the retina.



Our Treatment: In clinical trials, PRIMA restored form vision by replacing the function of damaged photoreceptors
Building on decades of pioneering research in miniaturized solar technology, the PRIMA system has two main parts: a small device placed under the retina where the eye's light-sensing cells have been lost; and a pair of glasses that sends both visual data and power in the form of patterned light that is projected on to the implant.
Once implanted, the PRIMA implant uses gentle electrical signals to activate healthy nerve cells in the eye. In our clinical trials, this process enabled some patients to read sequences of letters with a clinically meaningful improvement of letter acuity.

Science's PRIMAvera clinical study in Europe was focused on AMD and has been completed with positive preliminary results. This study evaluated the safety and efficacy of the PRIMA implant on patients with AMD. Based on these results, we have submitted an application for a CE mark to the European Union. A separate feasibility study in the US continues.
