Could lower eye pressure during cataract surgery reduce corneal damage?

NCT ID NCT06611670

First seen Jul 01, 2026 · Last updated Aug 14, 2026 · Updated 2 times

Summary

This study investigates whether using a lower, more natural eye pressure during cataract surgery reduces trauma to the cornea compared to traditional high-pressure methods. The Active Sentry device helps maintain stable pressure by sensing changes in the eye. Researchers will measure corneal thickness after surgery as an indicator of damage, and also track fluid use and surgery time. The study includes adults with similar cataracts in both eyes who have not had prior eye surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Active Sentry device
What this could lead to
If successful, this could lead to safer cataract surgery with less damage to the cornea and optic nerve.
What could go wrong
This is a small, early-stage study with 31 participants, so results may not apply to all patients. The benefits of lower pressure may not outweigh surgical efficiency.
