Current clinical practice utilises Goldmann applanation tonometry (contact-based); measures the force necessary to flatten a corneal area to measure intraocular pressure. The current non-contact “air-puff” tonometer is also based on applanation tonometry, but is subject to inaccurate reading because of its dependence on predetermined cornea thickness and rigidity assumptions. There is no current method to measure aqueous flow. Recent literature (35 reviewed) suggests the concept is theoretically sound but needs further work. The aim is to develop a novel non-contact diagnostic technique for measuring intraocular pressure and aqueous flow using “light” and “sound” radiation. The approach will refine the literature review, undertake a technical and technology feasibility study, and thereafter experimental design including identifying equipment requirements. The expected outcome is a prototyping for proofing the concept and potentially supported by industry partner(s). This project will involve initial scoping, definition, and evaluation of current technologies and practices, identify any constraints and parameters, and finally proposes conceptual design options that may fulfil the design objectives.
