PURPOSE
To analyse outcomes of lacrimal bypass surgery with the Medpor coated tear drainage tube.
METHODS
A total of 26 eyes in 26 patients with persistent epiphora who failed canaliculoanastomosis and dacryocystorhinostomy were treated by the lacrimal bypass surgery with the Medpor coated tear drainage tubes. Ten cases of severe obstruction of punctum and canaliculi and 16 cases with both upper system and lacrimal sac obstruction comprised this cohort of patients.
RESULTS
No tube extrusion or displacement was observed after 6-28 months of follow-up. Complete or significant resolution of epiphora was achieved in 23/26 cases (88.5%). Luminal obstruction by debris was noted in nine eyes, ocular discomfort in four, improper tube size selection in two, malposition in one, infection in one, diplopia in one, corneal abrasion in one, and reflux of intranasal secretion into fornix in another.
CONCLUSION
Medpor coated tear drainage tube offers tube stabilization in minimizing tube extrusion and displacement.
目的
分析使用Medpor涂层泪液引流管进行泪道旁路手术的效果。
方法
对26例经泪小管吻合术和泪囊鼻腔吻合术失败后仍持续溢泪的患者的26只眼，采用Medpor涂层泪液引流管进行泪道旁路手术治疗。其中包括10例泪点和泪小管严重阻塞患者以及16例上泪道系统和泪囊均阻塞患者。
结果
随访6 - 28个月后，未观察到引流管挤出或移位情况。26例中有23例（88.5%）溢泪完全或显著缓解。9只眼出现管腔被碎屑阻塞，4只眼有眼部不适，2只眼存在引流管尺寸选择不当，1只眼位置异常，1只眼感染，1只眼复视，1只眼角膜擦伤，另1只眼鼻内分泌物反流至穹窿部。
结论
Medpor涂层泪液引流管能使引流管稳定，最大限度减少引流管挤出和移位。
