AIM:To observe the efficacy and safety of RS-type lacrimal drainage tube and annular silicone tube placement in the treatment of lacrimal canaliculus laceration.

METHODS: Retrospective study. A total of 64 patients(64 eyes)with lacrimal canaliculus laceration were selected, and divided into group A(34 eyes treated with RS-type lacrimal drainage tube placement)and group B(30 eyes treated with annular silicone tube placement)according to different treatment. Clinical effect, operation time, regression time of postoperative eyelid swelling and complications at 3 and 6mo after surgery were compared between the two groups.

RESULTS:There was no statistically significant difference in the total response rate between the two groups at 3mo(94% vs. 87%)and 6mo(91% vs. 83%)after operation(all P<0.05). The operation time and regression time of postoperative eyelid swelling of group A were significantly shorter than those of group B(all P<0.001). The total incidence of complications in group A was significantly lower than that in group B(12% vs. 33%, P=0.037).

CONCLUSION:Both RS-type lacrimal drainage tube placement and annular silicone tube placement are effective in the treatment of lacrimal canaliculus laceration. However, the operation time of patients treated with RS-type lacrimal drainage tube is shorter, and patients recover faster after operation. In addition, the complications are fewer, and it is safer.
