PURPOSE: To evaluate the results of occlusion of the lacrimal punctum reversible with the use of thermosensitive plugs to treat the dysfunctional tear syndrome. METHODS: Eighteen eyes of 9 patients with dry eye were selected and subjected to reversible occlusion of the lacrimal punctum with the use of thermosensitive plugs and were followed for 60 days through the OSDI questionnaire, fluorescein staining, rose bengal staining and Schirmer's test. RESULTS: in all studied patients there was improvement in dry eye symptoms and in ophthalmic parameters studied. In only 1 of the patients, symptom improvement was small, and no decrease in dependence on lubricating drops. In the other 8 patients there was a decrease in the use of eye drops. During the study there were no infectious complications or extrusion. CONCLUSION: Temporary occlusion of the lacrimal punctum with SmartPlug tm seems to be an effective option for treating the dysfunctional tear syndrome when the use of lubricants is not enough. Its placement is relatively simple and safe, but longer studies are needed.
