Fewer drops, same relief? trial tests Twice-Daily systane complete against standard Four-Times-Daily regimen
NCT ID NCT07722650
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial investigates whether using Systane Complete eye drops twice a day works as well as using Thealoz Duo eye drops four times a day for adults with mild to moderate dry eye disease. Over 30 days, participants will use one of the two regimens and report symptom changes through a questionnaire, while doctors measure tear film stability and eye surface health. The goal is to see if a simpler dosing schedule can provide comparable symptom relief.
What this could mean

- What this could lead to
- If successful, this could offer a simpler, less frequent dosing option for managing dry eye symptoms.
- What could go wrong
- This is a small, short-term trial comparing two existing products, so any advantage may be modest or not apply to all dry eye patients.
