目的:探究泪道激光联合引流管植入对泪道阻塞患者泪膜破裂时间及角膜荧光素钠染色的影响,以便提高泪道激光联合引流管植入术对患者的治疗效果。方法:选取2013-01/2015-12在我院进行泪道激光联合泪道引流管植入术治疗的泪道阻塞患者200例200眼,分别在治疗前、术后1mo、拔管后进行眼表评估。检测内容包括患者泪膜破裂时间、泪液分泌量、角膜荧光素钠染色情况及干眼症状问卷等。结果:患者治疗前、术后1mo、拔管后泪膜破裂时间,三者间比较差异无统计学意义(P>0.05)。患者术后1mo泪液分泌量增加,拔管后泪液分泌量减少,差异有统计学意义(P0.05)。进行干眼症状问卷显示行泪道激光联合引流管植入术后流泪症状明显改善。结论:泪道激光联合引流管植入对患者泪膜破裂时间及角膜荧光素钠染色无明显影响,此种手术方式可以使患者术后流泪症状明显改善,在治疗泪道阻塞方面具有重大意义。
