Patent abstract
A new noninvasive approach for intraocular pressure (IOP) measurement allowing continuous monitoring over prolonged periods, regardless of patient's position and activities. The key element of this measurement method is a soft contact lens (1) including at least one strain gage (2) longitudinally arranged around the center of the contact lens and capable of measuring precisely spherical deformations of the eyeball induced by the changes in IOP. This information is transmitted with wires or (preferably) wirelessly in real time to an external recording system (14). The system is placed in the same way as a normal corrective contact lens, no anesthesia is required and patient vision remains almost completely unimpaired.
