Effects Of Smart Plug Lacrimal Plug In The Treatment Of Dry Eye

BACKGROUND AND OBJECTIVE:With the development of the economy, more and more people pay close attention to dry eye. The uncomfortable symptom of dry eye is followed with interest. The cause of dry eye is very complicated. At present, the clinical application of artificial tears still mostly to treatment. This paper applied Smart Plug lacrimal plug to treat dry eye, Smart Plug lacrimal plug to prevent tear outflow, make normal tear secretion reserves in the eye, thereby improving dry eye symptoms. So to evaluate the clinical efficacy of Smart Plug lacrimal plug in the treatment of dry eye.METHODS:A total of 42 patients were screened for dry eye from January 2009 to May 2010.42 patients (84 eyes) were inserted Smart Plug lacrimal plug to treat dry eye. All patients were follow up after 5- 15mouths (average 8.3 mouths). SchirmerⅠtest (SIT), Tear break-up time (TBUT) and Fluorescent of cornea (FL), were used for evaluation of the clinical efficacy.RESULTS:1. pre-and post-treatment, SchirmerⅠtest (SIT) respectively was 3.41±0.60mm and 5.75±0.44mm (P<0.05); 2. pre-and post-treatment, Tear break-up time (TBUT) respectively was 3.75±1.26 seconds and 6.46±1.47seconds (P<0.05); 3. Fluorescent of cornea (FL) respectively was 2.45±0.06fen and 0.04±0.02fen (P<0.05); 4. the subject symptoms were improved in most patients.CONCLUSIONS:Application Smart Plug lacrimal plug treatment dry eye, closed patients part lacrimal plug to prevent the tear outflow, make normal tear secretion reserves in the eye, thus improve symptoms, obtain good effect. So the conclusion: the Smart Plug lacrimal plug treatment effect, have clear dry eye clinically as a treatment method for dry eye can one. It is significantly simplified procedures and difficulty, also significantly reduces the actual autologous exclude rate, plug and lacrimal duct secondary infection. Improved dry eye the patient's eye table physiological micro environment, improve the patient's quality of life. Deserves further clinical research and promotion.
