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.
Claims42
A combination device for tonometric measurement and drug application on an eye, comprising:
- a device enclosure housing a tonometric measuring unit for acquiring an intraocular pressure (IOP) measurement of the eye and a drug administration unit for applying a drug to the eye;
- a drug reservoir attachable to the device enclosure, wherein the drug administration unit controls the withdrawal of a drug from the drug reservoir for application to the eye;
- and
- a communication unit for establishing a communication link to an external electronic device, and for exchanging information between the combination device and the external electronic device;
- wherein:
- the combination device includes a dosage monitoring unit that obtains a measure of the amount of drug applied to the eye;
- and
- the external electronic device includes an electronic data processor that determines an effectiveness-measure of individual drugs based on their applied dosage and consequent effect on monitored IOP measurement.
