Objective:

To present a new theranostic contact lens that monitors intraocular pressure (IOP) and administers glaucoma medications, combining therapeutic and diagnostic capabilities.

Approach:

Key Findings:

The lens can monitor IOP and release medication in response to pressure changes.
It is designed for comfort and flexibility, unlike existing bulky or electronic options, making it more user-friendly.
The device has potential for lower costs compared to current treatments.

Interpretation:

The new contact lens could improve glaucoma management by providing real-time monitoring and addressing medication adherence issues.

Limitations:

The drug release mechanism may not provide immediate effects due to the slow action of glaucoma medications, which could delay treatment.
Regulatory approval for the drug dispensing system may take longer than for the monitoring system.

Conclusion:

The device represents a significant advancement in glaucoma treatment, with potential applications in other medical fields, including ocular, neurological, and systemic diseases.
