Prima: The First Retinal Implant Approved for Vision Restoration
TL;DR
Prima, a brain-computer interface device developed by Max Hodak's company, has been approved in Europe as the first BCI implant for restoring detailed vision in age-related macular degeneration patients, with trial participants achieving five lines of improvement on an eye chart within 12 months.
Key Takeaways
- 1Prima is the first BCI device approved specifically for restoring detailed vision in age-related macular degeneration, a condition that destroys central retinal vision
- 2Patients using Prima experienced five lines of improvement on a standard eye chart after 12 months of use
- 3Prima works by converting visual signals into electrical signals delivered to remaining retinal cells, which transmit the information through the optic nerve to the visual cortex
- 4Max Hodak, the former president of Neuralink, runs the company developing Prima and launched it in Europe first
- 5Retinal implants are easier to scale to mass markets than direct brain electrode placement because they avoid direct brain intervention
Notable Quotes
“Prima is the first BCI device approved for restoring detailed vision and age related macular degeneration that destroys the central vision of your retina.”
“The patients who've gone through this have experienced five lines of improvement on a standard eye chart after 12 months.”
“This is reminiscent of an ocular implant from the Borg quite literally.”
Chapters
1. Introduction to Prima
Prima is the first BCI device approved for restoring detailed vision in age-related macular degeneration patients; developed by Max Hodak, former president of Neuralink
2. How Prima Works
The implant converts visual signals into electrical signals and delivers them to remaining retinal cells, which transmit through the optic nerve to the visual cortex to restore central vision
3. Clinical Results
Patients experienced five lines of improvement on a standard eye chart after 12 months of treatment
4. Scalability and Future Potential
Retinal implants are easier to scale to consumer mass markets than direct brain electrode interventions because they avoid the complexity of placing electrodes directly in the brain

Glossary
- BCI
- Brain-computer interface; a device that translates neural signals into digital commands or, in Prima's case, converts visual information into electrical signals
- Age-related macular degeneration
- A progressive eye condition that destroys the central vision (macula) of the retina, typically affecting older adults
- Retinal cells
- Specialized light-sensitive cells in the retina that normally convert light into neural signals; in Prima users, these receive electrical signals from the implant
- Optic nerve
- The nerve that transmits visual information from the retina to the brain's visual cortex
- Visual cortex
- The part of the brain's occipital lobe responsible for processing visual information and creating the sense of sight
