Two new prototype intraocular lens devices aim to continuously measure intraocular pressure from the inside of the eye for glaucoma patients. 

   Pre-IOP Sensor.

Researchers at Stanford University and Bar-Ilan University in Israel are jointly developing an IOL implant that would allow patients to use a smartphone or Google Glass to check their IOP level. 

Meanwhile, German-based Implandata Ophthalmic Products is working on the Pro-IOP, an implant that is powered telemetrically by a hand-held device. The patient or doctor would obtain IOP data from either the device or a smartphone app.
