Could light and sound replace the air puff eye test?
NCT ID NCT07762053
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial evaluates a new device called the Photobionic IOP Tonometer (PIB) that measures eye pressure without touching the eye or using an air puff. It uses a low-power infrared light and a gentle sound to detect tiny movements on the eye's surface, which a computer analyzes to estimate pressure. The study involves 15 adults with or without glaucoma, comparing PIB readings to the standard Goldmann applanation tonometer (GAT) to check repeatability and safety. The goal is to see if this method could offer a faster, more comfortable, and potentially home-based way to monitor eye pressure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Photobionic IOP Tonometer (PIB) - a non-contact device using infrared light and sound waves to measure eye pressure
- What this could lead to
- If successful, this could lead to a painless, touch-free way to measure eye pressure at home, improving glaucoma monitoring and access to care.
- What could go wrong
- This is a small early study focused on repeatability, not accuracy. The device is investigational and not yet FDA-approved, and results may not confirm it works as intended.
