2000 – Dr. Alan chow and brother Vincent announced they successfully placed a silicon microchip beneath human retinas. The chip is smaller than the head on a pin and only microns thin. These chips also contain solar cells to help power the chip.


In what is called “Optobionics”, the ASR chip is inserted behind the retina in the “subretinal space”. This is a 2 hour procedure and the chip can last up to 8 years after (depending on care).
