Topical Osmoprotectant for the Management of Postrefractive Surgery-Induced Dry Eye Symptoms: A Randomised Controlled Double-Blind Trial
(a) Tear osmolarity mean and SEM values compared between FT and Op groups before surgery (T0) and 1 month (T1) and 3 months (T3) of treatment. FT group presented a significant reduction in osmolarity values after 3 months of treatment (ANOVA-Tukey, ). In the Op group, reduced osmolarity was noted between T0 and T1 and T0 and T3 (ANOVA-Tukey, ). (b) Schirmer 1 test mean and SEM values. An increase was observed for Op group, in T1 only (Friedman test, ).
