ABSTRACT

AIM: To discuss the effect of Smart Plug canalicular plug on aqueous-deficient dryeye. METHODS:Forty-eight cases of aqueous-deficient dry eye patients in our hospital from May 2012 to April 2013 were selected for the study. After treated by Smart Plug canalicular plug, postoperative clinical efficacy, foundation Schirmer I test ( SIt) , tear film break-up time ( BUT ) , corneal fluorescein staining ( FL ) changes were observed. RESULTS: Forty-eight patients were cured, 31 cases were markedly effective(65%), effective 14 cases (29%), invalid in 3 cases (6%), the total effective rate was 94%. Before treatment, SⅠt, BUT, and FL was ( 3. 49±1. 24 ) mm/5min, ( 3. 15±1. 07 ) s, and ( 2. 52±0. 11 ) points, respectively. After treatment, SIt, BUT, FL were significantly improved compared with before treatment, the difference was statistically significant (PCONCLUSION: Smart Plug canalicular plug is an effective treatment for aqueous-deficient dry eye, can effectively relieve symptoms, worthy of promotion.
