Contact lens that prevents optic nerve damage by glaucoma
Early detection and prevention of glaucoma always pays-off as-far-as long term health issues go. For this very reason researchers at EPFL in association with Tissot Medical Research in Neuchatel and Haute Ecole Arc have are developing a single-use contact lens that can measure intraocular pressure for a duration of 24 hours. The contact lens is made-up of silicone and every time the patient blinks, the protuberance of this lens measures pressure in the eyes 24×7. The lens has a ring with capacitive sensors of electrodes that register the distance between the electrodes to indicate intraocular pressure when the eyelid closes.
The information collected is then captured by glasses equipped with small antennas and send to a small portable box. After a period of 24 hours the ophthalmologist plugs-in the box into the computer to analyses the results.
According to Dr Katia Tissot, the medical manager for the society, these lenses are undergoing clinical trials at the Ophthalmic Hospital of CHUV. Adding to that Katia said that it could also be possible measure the biomechanical properties of the cornea using these lenses.
The development of this lenses will surely allow ophthalmologists to detect this insidious disease at a very early stage, thereby preventing any damage to the optic nerve. Also these lenses will ensure around the hour detection of any changes in the intraocular pressure.
