What this research studies

You would be using a bandage contact lens that has a thin drug-polymer film built into its edge to steadily release the anesthetic tetracaine over time. The goal is to give longer-lasting pain relief than eye drops and reduce the need for oral opioids. Early animal tests showed up to 30 hours of reduced pain without harming wound healing. The project will optimize the lens design, map drug distribution, check safety and biocompatibility, and prepare for a first-in-human trial.

Who could benefit from this research

Good fit: People with acute corneal pain from injury or recent eye surgery who are candidates for wearing a bandage contact lens.

Not a fit: People who cannot wear contact lenses, have known allergy to local anesthetics, active corneal infection, or certain chronic corneal diseases may not be eligible or benefit.

Why it matters

Potential benefit: If successful, this could offer safe, long-lasting local pain relief after corneal injury or surgery and reduce reliance on oral opioids.

How similar studies have performed: This is a novel approach for patient use: animal studies have shown promising pain reduction, but there are currently no FDA‑approved self-administered ocular anesthetics.
