Device allows doctors to track intraocular pressure over 24 hours.
Scientists in France have developed a single-use contact lens for the detection of glaucoma. The lenses will allow ophthalmologists to track intraocular pressure over a 24-hour period, thus enabling them to bypass the problem of IOP pressure rates peaking at night or early in the morning. The lenses operate by pressing a small protuberance within the lens into the cornea every time the patient blinks. Inside the lens there is a rigid ring which contains a sensor formed of electrodes. The information is collected by small antennas connected to a pair of glasses given to the patient, which is further connected to a portable, wallet-sized storage device. After 24 hours ophthalmologists will be able to transfer and review the data collected.
