AIM:To investigate the clinical treatment method and efficacy of the artificial nasolacrimal duct and silicone tube conjunct implantation in treatment of lacrimal puncta or lacrimal canaliculus stenosis with nasolacrimal duct obstruction or chronic dacryocystitis.METHODS:Twenty-three cases (28 eyes) were diagnosed with lacrimal puncta or lacrimal canaliculus stenosis with nasolacrimal duct obstruction or chronic dacryocystitis,after nasolacrimal duct probing they were treated with the artificial nasolacrimal duct and silicone tube conjunct implantation.RESULTS:Removed the artificial nasolacrimal duct and silicone tube at the end of the fourth month after surgery and followed-up for 1 year.23 eyes of 23 cases (28 eyes) were cured with no epiphora,the cure rate was 82%.2 eyes were improved with slight epiphora,the improvement rate was 7%.Lacrimal canaliculi were still obstructive in 2 eyes,and 1 eyes reappeared pyoid secretion,which were ineffective,the ineffective rate was 11%.CONCLUSION:The artificial nasolacrimal duct and silicone tube conjunct implantation is effective in treatment of lacrimal puncta or lacrimal canaliculus stenosis with nasolacrimal duct obstruction or chronic dacryocystitis.
