Sensor placed in eye can track intraocular pressure changes

A low-power sensor has been developed by researchers at the University of Washington that can be placed permanently in the eye and can monitor changes in eye pressure. This lens is implanted during cataract surgery and can immediately detect changes in pressure within the eye. The sensor transmits data via radio frequency waves. Glaucoma is often not detected until irreversible damage has occurred. The sensor may allow doctors to diagnose glaucoma at a much earlier stage,  thus allowing for earlier treatment before vision loss. Implanting the sensor is performed during cataract surgery.*
