Other companies are developing implantable devices for permanent continuous IOP monitoring. Two manufacturers that have information about their technology are Implandata Ophthalmic Products and AcuMEMS, Dr. Katz said.
Implandata is working on two versions of its device, which is called EyeMate. One version uses a sensor placed in the sulcus during cataract surgery and the other is designed for subconjunctival or subscleral implantation.
AcuMEMS is developing two versions of its device, the iSense System. One version is placed with an intraocular lens into the capsular bag after cataract surgery and the other is for anterior chamber placement at the time of a stand-alone glaucoma procedure.
Both manufacturers have completed animal studies that had positive results, and Implandata has begun clinical trials.
