New eye drop battle: can ectoin beat hyaluronic acid for dry eyes?
NCT ID NCT01684852
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of eye drops—ectoin (BAT04) and hyaluronic acid—for treating dry eye disease. 64 adults with mild to moderate dry eye used the drops six times daily in both eyes for 28 days. The main goal was to see how well each drop improved tear film stability, measured by tear break-up time. Results were recorded at the end of the treatment period.
