Abstract

Glaucoma affects a significant portion of the global population, necessitating regular monitoring of intraocular pressure (IOP). Existing methods are limited by expensive equipment and infrequent measurements. This study proposes an implantable interferometric device for accurate, easy to use, handy and accessible IOP measurement. The device operates through reflection, receiving light from a near-infrared source. A retroreflector directs the light to a spectrometer for analysis. The device consists of a movable membrane and a fixed membrane, with pressure changes leading to spectral variations in the transmitted light. The system achieves a resolution of ~2nm, enabling precise IOP measurement. The design addresses the limitations of current approaches and offers a practical solution for accurate IOP monitoring.
