目的：探讨应用VisiPlug可降解泪小管塞栓治疗中度干眼的临床疗效。方法：选择2011年1月至2012年3月于我院就诊的31例62眼、诊断为干眼的患者使用VisiPlug可降解泪小管塞栓术治疗,随访3-16个月,根据干眼症状的问卷调查、SchirmerⅠ试验（SIT）、泪膜破裂时间（BUT）及角膜荧光素染色（FL）检查观察临床疗效。结果：术后93.5%患者眼干涩感、异物感、烧灼感、痒感、畏光、眼红、视力波动、视疲劳等症状减轻;BUT延长、SIT增加、FL恢复阴性;所有患者未见感染、肉芽肿形成;1例患者在术后2周发生栓子脱出,经再次补植入,未再发生脱出及其他异常。结论：VisiPlug泪小管栓治疗干眼在临床上安全可行,但仍需进一步观察和改进。
