Abstract
Objective To compare the application efficacy between RS-type lacrimal intubation and tear duct drainage stent in the anastomosis of lacerated lacrimal canaliculus. Methods The data of 78 eyes of 78 cases with lacrimal canalicular laceration were collected.All cases were randomly divided into 2 groups. Group A, 38 cases were treated with RS-type lacrimal stent and 40 cases were treated with drainage stent in group B. All patients were removed the stent 3 months after surgery. The differences of operative time, intraoperative comfort, efficacy and the rate of complications between the two groups were compared. Results The operation time of group A was (61.71±8.79) min, and group B was (68.25±7.56) min. The difference was statistically significant (t=3.527, P=0.001). The intraoperative pain score of group A was 3.58±0.83 and 4.20±0.97 of group B (t=3.044, P=0.003). The total rate of complications was 20.0% in group B and 15.8% in group A (χ2=0.235, P=0.656). The postoperative evaluation was made when removed the stent 3 months after operation. The total effective rate of group A was 92.1%, while that of group B was 90.0%(χ2=0.106, P=0.752). Conclusion Applications of two stent in surgery are effective, which are ideal supporting materials. However, RS-type lacrimal stent is superior to lacrimal duct drainage stent with short operation time and good intraoperative comfort.
