Project period: 1/2/2016 – 31/7/2019

PhD Project Description

Primary open-angle glaucoma (POAG) is one of the leading causes of visual impairment and blindness, which affected more than 57.5 million people globally in 2015 especially the middle-aged and older people.

Increased intraocular pressure (IOP) is known to be a risk factor for the development and progression of the optic nerve degeneration and visual field loss characterizing the disease. Therefore, patients at risk are subjected to regular examinations with an ophthalmologist to see if the changes in the optic nerve and the visual field are progressing. However, it is known that the intraocular pressure shows diurnal variations, and especially IOP peaks during night are suspected to constitute a particular risk factor for progression of the disease. Therefore, it might improve the treatment considerably if the IOP is continuously measured.

The purpose of this project is therefore to design an eye contact lens for continuous monitoring of the intraocular pressure, which envisions integratability with a drug-delivery contact lens in the future. The proposed system includes sensors, electronics (processing and communication) that is powered by solar cells, a Radio-Frequency Energy harvester and a piezoelectric harvester for sleeping state. By the use of this technique, primary open angle glaucoma can be monitored more closely and treated more accurately.

External Partners: This is a shared PhD with Macquarie University in Australia where Michael Heimlich is professor.
