Can a simple eye drop boost glaucoma surgery success?
NCT ID NCT03933631
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding pilocarpine eye drops after combined cataract and Kahook Dual Blade surgery helps lower eye pressure more than standard drops alone. About 142 adults with glaucoma or high eye pressure will take part. The goal is to see if more patients achieve a 20% or greater reduction in eye pressure with pilocarpine.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pilocarpine eye drops
- What this could lead to
- If it works, this could show that adding pilocarpine after surgery helps lower eye pressure better than standard care alone.
- What could go wrong
- This is a single-center trial with 142 participants, so results may not apply to everyone. Pilocarpine can cause side effects like blurred vision or eye irritation.
