After stepping down as Neuralink's inaugural president, Max Hodak established the brain-computer interface company Science Corporation. The firm's PRIMA implant has successfully restored "artificial vision" to blind patients, empowering them to read texts and solve crossword puzzles. PRIMA is a subretinal microelectronic chip that is surgically placed beneath the patient's retina in a procedure that takes roughly 80 minutes. Following the implantation, patients need to wear a specially crafted pair of glasses fitted with a camera. These glasses capture visual data and send signals to the chip through infrared light. Upon receiving these signals, the chip generates pulsed electrical currents. These currents circumvent the damaged photoreceptor cells caused by macular degeneration, directly stimulating the retina. The chip transforms light signals into electrical signals and conveys them to the brain, ultimately creating vision. This groundbreaking research has been published in The New England Journal of Medicine.
