The Science Behind PRIMA: A Technological Marvel

The PRIMA implant functions as a sophisticated visual prosthesis. It comprises a tiny microchip, approximately 3mm by 3mm, which is surgically implanted onto the retina. This chip is designed to replace the function of damaged photoreceptor cells, the light-sensitive cells in the eye that are critically affected by AMD. The implant works in conjunction with an external camera and processing unit, typically worn as eyeglasses. This external system captures visual information, processes it, and transmits it wirelessly to the implanted chip. The chip then stimulates the remaining healthy retinal cells, sending signals to the brain that are interpreted as visual perception.

The development of PRIMA has been a multi-year endeavor, involving extensive research and clinical trials. The journey from concept to regulatory approval highlights the complex and often lengthy process of bringing advanced medical devices to market. While the precise timeline for the initiation of commercial sales in Europe was not detailed in the initial announcement, the approval signifies that the device has met rigorous safety and efficacy standards set by European regulatory bodies.
