Summary

This study tested two different eye drop treatments for people with dry eye disease who were having cataract surgery. One group used a single medication (rebamipide), while the other used a combination of two medications (diquafosol and cyclosporine). The goal was to see which approach better kept the eyes moist and comfortable before and after surgery. Fifty-five adults participated, using the drops for one month before surgery and three months after, with regular eye exams to measure tear stability, symptoms, and safety.
