Mass Device has interviewed the CEO of SENSIMED AG, a company out of Lausanne, Switzerland that has developed a contact lens capable of continuously measuring intraocular pressure. The lens is composed of a strain gauge and a microchip to process the data off the instrument. The patient also wears an antenna array around the eye socket that powers the lens and reads the information coming off the microchip. Clinicians can then assess an entire day’s worth of patient’s intraocular pressure back at the clinic. We’ve written about the development of the contact lens before, but we must have missed last February’s European approval of the SENSIMED Triggerfish® system.
Triggerfish system components:
Sensor: Soft, hydrophilic silicone disposable contact lens embedding a MEMS sensor and a telemetry microprocessor. The sensor comes in three different base curves. All elements embedded in the lens are excentric, out of the line of sight. Antenna and datacable: A circular antenna taped around the eye which sends energy to the sensor and receives the measurement information. The antenna is connected to the portable recorder through a thin flexible datacable. Recorder: A battery powered recorder which will store measurement information and wirelessly upload this information on the ophthalmologist’s computer at the end of the monitoring session. Software: The software running on the ophthalmologist’s computer to retrieve and to visualize the intraocular pressure profile.
