Description of intervention(s) / exposure
Sixty-six postmenopausal women with dysfunctional tear syndrome (DTS) were enrolled in a randomized, double-blind, placebo-controlled, cross-over study. Patient were divided into two groups (Group A and Group B) and treated respectively with Lacrisek ( alpha lipoic acid100mg,phytoestrogen 200mg, fish oil 240mg),Registered Trademark, tablets or placebo tablets, twice a day for 30 days. The two treatment periods were separated by a 30-day washout. Patients were examined on day 0 and day 30 of each period. Assessments included blood levels of sex hormones, the Schirmer test for tear production, and measurement of tear osmolarity and tear film break-time (T-BUT).

Secondary outcome [1] 273668 0
To asses that improvement of tear film function is limited in time. We valued Schirmer test,T-BUT (tear film break-up time), Tear osmolarty after 30 days after discontinuation of theraphy with Lacrisek.

after 30 day of intervention
