Your eye could someday house its own high-tech information center, tracking important changes and letting you know when it’s time to see an eye doctor.
University of Washington engineers have designed a low-power sensor that could be placed permanently in a person’s eye to track hard-to-measure changes in eye pressure. The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously, then transmit the data wirelessly using radio frequency waves.
The researchers recently publishedtheir results in the Journal of Micromechanics and Microengineering and filed patents on an initial prototype of the pressure-monitoring device.
“No one has ever put electronics inside the lens of the eye, so this is a little more radical,” said Karl Böhringer, a UW professor of electrical engineering and of bioengineering. “We have shown this is possible in principle. If you can fit this sensor device into an intraocular lens implant during cataract surgery, it won’t require any further surgery for patients.”
