Plant a 2mm -sized chip into the retina, and with a pair of camera glasses, you can successfully restore the blind people to the vision!
Not only regain reading ability, but even play cards.
This is the latest progress of the brain -machine interface company from California, USA.
And this company is created by Musks front below .
CEO Max Hodak of Science was a new and president of Neuralink.
In 2021, Hodak left Neuralink and founded Science.Essence
Today, Science has announced the preliminary clinical trial results of the chip.
surgery for 80 minutes, let the blind people see the light
This implant is called PRIMA, about 2mm size.It needs to be implanted with the retina through surgery, and the surgical process is about 80 minutes.
After the implantation is completed, Prima needs to be used with the supporting glasses with cameras.
The principle of Prima is capture visual information with a camera and emit infrastructure patterns to the chip. After receiving the pattern, the light is converted to the electrical signal and sent to the brain to the brain..
However, Prima just helps patients to re-get simple visual ability such as reading text and distinguish between people to a certain extent.
The images seen by the patients are still different from normal people -because the infrared light is emitted to the chip, the patient cannot see the color, and the black and white is the opposite of the real world.
But compared to being completely invisible, it is a good result to read the text and distinguish the face.
At the beginning, Prima was a research project of Professor Daniel Palanker University of Stanford University, which was taken over by the French company Pixium Vision Sa.
Pixium was established in 2011 and was listed on the Paris Stock Exchange in 2014. In April this year, Pixiums assets, including the ongoing clinical trials, were acquired by Science.
The preliminary results of clinical trials have also been released.
Standard vision table, patients with average see the five elements
Experiment, Science (and previous Pixium)38 patients from European and over 60 -year -old atrophy (GA) patients were selected, with an average age of 78.9 years.
GA is a late form of dry age correlation with macular degeneration (AMD), which can cause irreversible vision loss and will become the number one killer for the elderlys vision damage.
The patients participating in the test, obvious lesions in the central area of the retina, of course, the central vision also deteriorated.
The results show that when patients use PRIMA, their vision has been significantly improved. When reading a series of letters, the acuity increases significantly, and some people can even read longer texts.
In the classic vision table, the average vision of the patient at the beginning was 20/450 (normal vision was considered 20/20, and it was defined as 20/200 or worse in the United States.blindness).
One year later, 32 subjects could read nearly 5 lines on the vision table, that is, 23 letters, that is, the average vision increased to 20/160.
If the built -in zoom and amplification function of the implant is used, the vision of some participants can even reach 20/63, which is reflected in the vision table, which is to see 11.8 lines.
In quantitative, when the researchers are 6 months and 12 months after implantation, the vision of all patients can be scored through the LOGMAR scoreThe measurement (logar is 0 to indicate that the vision is normal, which means that the vision is not good), and the results show that the clinical significance improves:
Moreover, the average natural vision of patients does not use PRIMA to maintain stability after implantation shows that the PRIMA implants have good safety.
For the prospects of Prima, the clinical spokesman of the American Eye Science Association, who has not participated in research, said:
In various chip implantation technologies that have been tried for a long time, this technology seems to have certain feasibility. It is expected that this device will need huge demand because AMD is the main reason for the visual impairment of the elderly.
