Present technology far exceeds a common man’s thought, and there are a countless number of ways it is helping us fight diseases. Taking this idea further, SENSIMED AG, a Swiss company, has built a contact lens that measures the intraocular pressure continuously. A strain gauge (MEMS sensor) and a microchip (telemetry microprocessor to process data from the gauge), are embedded in the lens. This provides information about fluctuating pressure, during night and day, in a Glaucoma patient.
The microchip sends the processed info to the antenna array that surrounds the eye socket. The antenna array also supplies the necessary power for operation to the microchip and is connected to a battery-powered recorder that stores the received info and uploads it wirelessly onto an ophthalmologist’s computer, when required. This system of lens, antenna and the recorder is together known as Triggerfish. There is a special software to read the processed info and display it in the form of graphs or visuals.
