Smart Contact Lens for Glaucoma IOP Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for primary open-angle glaucoma (POAG) rely on coarse dosing schedules for lowering intraocular pressure (IOP), which are not patient-specific and do not account for the complex circadian rhythms affecting IOP fluctuations, leading to suboptimal therapeutic outcomes and poor patient compliance.
Innovation Solution
A chronotherapeutic system, such as a smart contact lens with integrated IOP monitoring and pulsatile drug delivery, synchronizes therapeutic agent administration with the patient's circadian rhythms using a processor-driven temporal model to optimize IOP management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If coarse dosing schedules are used for therapeutic agent administration, then device complexity is reduced and ease of operation is improved, but manufacturing precision of IOP regulation deteriorates and reliability worsens
Solution Approach 1:
The system continuously monitors IOP levels and uses this feedback to automatically adjust therapeutic agent delivery timing and dosage, transitioning from fixed coarse schedules to dynamic patient-specific dosing that maintains reliable IOP control
Solution Approach 2:
The dosing schedule transforms from static coarse intervals to dynamic timing that adapts to real-time IOP measurements and patient-specific circadian rhythms, optimizing both reliability and personalization
2Device complexity
If coarse dosing schedules are used, then device complexity is reduced, but manufacturing precision of therapeutic delivery deteriorates
Solution Approach 1:
The system pre-determines optimal dosing parameters based on initial IOP monitoring and patient characteristics, then executes these pre-calculated precise delivery schedules, achieving high precision without requiring complex real-time decision-making hardware
Solution Approach 2:
The system adjusts dosing parameters (timing, duration, dosage amount) based on measured IOP values and circadian rhythm patterns, enabling precise therapeutic delivery through parameter optimization rather than complex mechanical or electronic systems
3Manufacturing precision
If patient-specific dosing schedules are implemented, then IOP regulation precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system automatically performs IOP monitoring, data analysis, and dosing schedule generation without requiring complex user intervention, making the sophisticated precision dosing system as easy to operate as simple conventional drops while maintaining high regulatory precision
4Manufacturing precision
If continuous IOP monitoring and pulsatile drug delivery are integrated, then IOP regulation precision and therapeutic outcome are improved, but device complexity increases
Solution Approach 1:
The system combines IOP sensing, circadian rhythm analysis, and therapeutic agent delivery into a single integrated eye-mountable device, achieving precise IOP regulation through unified functionality while minimizing the number of separate components and interfaces the patient must manage

AI summary
Systems, eye-mountable devices, and methods that facilitate chronotherapeutic treatment of primary open-angle glaucoma are provided which enable therapeutic products to be delivered to the eye in a controlled manner only when desired. According to one embodiment, an eye-mountable device comprises a substrate having an eye-mounting surface for positioning on an eye of a patient, a sensor that obtains a plurality of measurements representative of a condition of the eye of the patient over a period of time, a therapeutic agent delivery assembly coupled, and a processor for executing a temporal model of a therapeutic agent delivery in communication with the sensor and the therapeutic agent delivery assembly. The processor receives the plurality of measurements and activates the therapeutic agent delivery assembly to administer a first amount of a drug to the eye of the patient based on the temporal model associated with the plurality of measurements.
