New ‘MR Unsafe’ contact lens, Triggerfish, used to monitor intraocular pressure

March 9th, 2016

The US Food and Drug Administration (FDA) has approved the Triggerfish (Sensimed AG, http://www.sensimed.ch/en/) contact lens sensor that provides an automated recording of continuous eye pressure changes over the course of 24 hours.

“The Triggerfish gives the clinician 24-hour continuous monitoring of changes in [intraocular pressure (IOP)] patterns that otherwise could not be obtained,” William Maisel, MD, MPH, acting director of the Office of Device Evaluation in the FDA’s Center for Devices and Radiological Health, said in a news release. “This information can help determine the most critical time of day for the clinician to measure the patient’s IOP.”

According to the manufacturer, this device is MR Unsafe.

As stated:
Do not wear the SENSIMED Triggerfish® while exposed to intense electromagnetic fields such as MRI (Magnetic resonance imaging) which could result in severe eye burn.
