Abstract

The proposed combination device combines any tonometric metrology with a drug application to administer glaucoma medication on an eye. Several technical concepts are proposed and exemplary embodiments for rebound tonometry and air-puff tonometry are shown. However other methods such as optical coherence elastography (OCE) could also be used. The Solutions provide home care tonometry offerings which host the capability to administer glaucoma medication.
