AIM: To investigate the efficacy and influence factors of lacrimal plastic operation combined with lacrimal duct intubation for the treatment of lacrimal duct obstruction.

METHODS: Totally 141 cases(146 eyes)with lacrimal duct obstruction treated in our hospital during May 2012 to December 2012 were selected, followed up for 3-6 months. The lacrimal recanalization rate, position of lacrimal duct obstruction, age and disease process to surgery effect were observed.

RESULTS: The general recurrence rate in 141 cases(146 eyes)was 82.9%(121 eyes), improved rate was 13.7%(20 eyes), no effect was 3.4%(5 eyes). The cure rate of Lacrimal duct obstruction(87.2%)was higher than lacrimal canalicular obstruction(82.9%)and nasolacrimal duct obstruction(75.9%), but there was no statistical difference(P>0.05). The cure rate of young group(88.4%)was higher than middle age group(82.4%)and senile group(75.9%), but there was no statistical difference(P>0.05). The cure rate of less 10 years was 93.8%, more than 10 year was 74.4%, there was statistical difference(χ²=9.58, P<0.001=0.009).

CONCLUSION: Lacrimal plastic operation combined with lacrimal duct intubation for the treatment of lacrimal duct obstruction is simple and efficacy. The patients' process may be the main reason of cure rate.
