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(P<0.05). One patient had postoperative foreign body sensation, 8h after shedding emboli; One patient granulation tissue after surgery 8mo, canalicular plug off. The remaining cases had no inferior lacrimal duct infection or granuloma.
CONCLUSION:Smart Plug canalicular plug is an effective treatment for aqueous-deficient dry eye, can effectively relieve symptoms, worthy of promotion.
