AIM:To observe the clinical effects of using "Y"-shape kieselgel tube flyback embedding to treat obstruction of lacrimal passages.·METHODS:All 380 patients(428 eyes) with obstruction of lacrimal passages were treated with "Y"-shape kieselgel tube stent flyback embedding.Clinical effects were analyzed after the patients were observed for 4 weeks-6 months.·RESULTS:All 380 patients lacrimal passages(428 eyes)were unobstructed when the "Y"-shape kieselgel tubes were removed,the symptom of epiphora vanished or improved obviously.342 patients (388 eyes) were observed for 4 weeks-6 months,the cure and effective rate were 90.7% and 98.7%,the relapse rate was 1.3%.·CONCLUSION:The way of using "Y"-shape kieselgel tube stent flyback embedding to treat obstruction of lacrimal passages is simple,economical,safe and effective.
