Glaucoma Diagnosis

About

Invention The novel non-invasive intraocular pressure (IOP) monitoring system comprises of a contact-lens sensor and a wearable reader. Novelty of the system rests in the use of capacitance change for measuring curvature changes, and the corrected in vivo corneal elastic modulus, which gives more accurate IOP measurements. The system will enable medical practitioners to record IOP for a longer period of time, which would likely facilitate more accuracy diagnosis of glaucoma.   Market Opportunity Glaucoma is a leading cause of visual impairment and blindness. Through regular IOP measurement, early diagnosis of glaucoma could be made possible. However, traditional static IOP measurement only allows record of IOP data within a short period of time. Such limitation has resulted in misdiagnosis. With the more accurate IOP data provided by this system, doctors will be able to diagnose more accurately. Further, in contrast with other traditional instrument, with the use of the contact-lens sensors, this system would be able to provide patients with a more comfortable, safe, and easy to accept way of IOP measurement and therefore would also encourage early diagnosis. Based on the novel technique, a contact lens-based IOP sensing system prototype has been developed and would be ready for testing.   Key Benefits Non-invasive, more accurate, safe, and easier to be accepted by patients Cost of apparatus is low
