Solar Powered Eye Implant Tests for Glaucoma

A cornea-implanted computer can monitor the eyeball's pressure

Today's method for glaucoma testing - gauging internal eye pressure by poking
the cornea with a probe—has several drawbacks, not the least of which is the
fact that variations in eye pressure might cause a doctor to miss signs that
glaucoma is progressing. But researchers at the University of Michigan say
they have developed an implant that takes readings of the eye's internal
pressure every 15 minutes. To prevent its battery from being drained after a
month, the sensor has a miniature solar panel that keeps the battery topped
up with just over an hour of sunlight a day.
