NCT ID NCT07451184
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two lubricating eye drops—Systane PRO PF and Thealoz Duo—to see which one better relieves dry eye symptoms. About 100 adults with dry eye will use each drop for 4 weeks, one twice a day and the other four times a day. The goal is to find out if they work equally well or if one provides superior comfort.
