Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current external eye pressure measuring devices are often inaccurate due to dependence on corneal rigidity and eye wall factors, and require frequent clinical visits for intraocular pressure monitoring, which can lead to delayed detection of high pressure and potential eye damage.
Innovation Solution
Development of an ocular self-exam device with optical components and a digital camera system that allows users to view and image intraocular sensors implanted in the eye, providing magnification, focus control, and a method for detecting intraocular pressure levels through visual or digital indicators, enabling self-monitoring and remote data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external eye pressure measuring devices contact the cornea or use pneumatic displacement, then IOP measurement is achieved, but measurement accuracy deteriorates due to dependence on corneal rigidity and eye wall factors
Solution Approach 1:
The patent uses an optical intermediary (light) to transmit pressure information from the intraocular sensor to the external reader device. The sensor converts mechanical pressure into optical signals that can be read remotely, eliminating the need for direct mechanical contact between the measuring device and the eye, thus avoiding the reliability issues associated with corneal rigidity variations.
Solution Approach 2:
The patent replaces the mechanical measurement system (contact tonometry or pneumatic displacement) with an optical system. The intraocular sensor uses optical principles to detect pressure changes and transmit them wirelessly to an external reader, substituting mechanical interaction with optical signaling to achieve more reliable and accurate measurements.
2Productivity
If frequent clinical visits are required for IOP monitoring, then measurement frequency is increased, but loss of time and convenience deteriorates for patients
Solution Approach 1:
The patent enables patients to perform self-monitoring of their IOP at home using a portable reader device. The patient simply positions the reader over their eye to obtain measurements, eliminating the need to travel to clinical facilities. This self-service capability allows frequent monitoring without the time loss associated with clinical visits.
Solution Approach 2:
The patent employs an implantable sensor that continuously monitors IOP and stores data locally before retrieval. The sensor is pre-positioned in the eye and ready to provide measurements at any time, eliminating the need for preparation or scheduling associated with clinical visits. Data can be retrieved on-demand by the patient using the portable reader.
3Duration of action of stationary object
If delayed detection of high IOP occurs between check-ups, then monitoring interval is extended, but harmful effects increase due to potential eye damage
Solution Approach 1:
The patent implements continuous IOP monitoring through an implantable sensor that operates 24/7 within the eye. The sensor continuously measures pressure and stores temporal data patterns, providing uninterrupted monitoring between retrievals. This continuous action ensures high IOP events are detected immediately, eliminating the monitoring gaps that occur between clinical visits or self-checks.
Solution Approach 2:
The patent creates a feedback loop where the implantable sensor continuously monitors IOP and the patient can retrieve data using the portable reader. When high IOP is detected, the patient receives immediate feedback through the retrieved data and can take prompt action by contacting their healthcare provider, preventing delayed detection and potential damage.
