Nanoarray-enhanced Implantable Intraocular Pressure Sensor with Remote Optical Readout

Abstract

An elevated intraocular pressure (IOP) is a major risk factor of glaucoma, which is the second leading cause of blindness [1]. Traditional IOP-detection techniques such as tonometry cannot provide direct, accurate, and continuous IOP measurements [2]. Recently explored LC-resonator IOP-sensing implants are limited by their large sizes and short readout distances [3]. Our compact, robust IOP-sensing implant can greatly improve clinical management of glaucoma and accelerate related drug discoveries.
