Science Corporation implants its vision-restoring chip in its first Stargardt disease patient

Science Corporation CEO Max Hodak announced that the company has implanted its vision-restoring chip, PRIMA, into its first patient with Stargardt disease, an inherited eye disease that gradually destroys central vision. Hodak, the former president and co-founder of Neuralink, the brain implant company, explained on stage at TechCrunch Disrupt how the company’s work with PRIMA fits into its broader pursuit of a novel brain-computer interface (BCI).

“The retina is part of the central nervous system,” Hodak said on stage. “We consider cochlear implants, retinal prostheses, motor prostheses, these are all different types of BCIs.”

Hodak outlined a vision in which BCIs expand into a wide range of medical technology applications, rather than simply being a way to control computers.

While PRIMA is commercially available in Europe for patients who’ve lost their sight to geographic atrophy, an advanced form of age-related macular degeneration, the company believes its approach can be applied to multiple diseases, including Stargardt disease, which is currently considered incurable.

Stargardt disease affects the outer retina, causing the gradual death of the eye’s light-sensing cells while potentially sparing the inner retina, the part that passes visual signals onto the brain. It causes a central blind spot that gradually enlarges over time. Approximately 150,000 people worldwide have lost vision due to the disease.

“One of the nice things about this device approach, when I was saying the brain’s a computer, vision is electrical potential, like electrical activity down the optic nerve,” Hodak said. “That’s all vision is to the brain, and so if you can get the optic nerve to signal the the rest of the brain correctly, then you can provide vision to it.”

The company has said it believes the device could help address neurological conditions, such as possibly monitoring neurological activity in patients with brain tumors.
