目的:探讨泪道塞在LASIK术后早期对干眼症状的影响。方法:随机选取在我院接受LASIK手术的患者54例108眼,其中27例54眼术后第2d植入诊断性泪道塞,另外27例54眼给予倍然眼药水点眼,于术后2wk进行泪液分泌试验(SchirmerⅠtest,SⅠt)、泪膜破裂时间(breaking-uptime,BUT)和荧光素染色(FL)评分。结果:泪道塞组与倍然组泪液分泌实验结果分别为11.90±4.20,10.85±3.42mm/5min,两组间差异无统计学意义(P>0.05)。泪道塞组与倍然组BUT分别为13.12±2.58和11.67±3.29s,两组间无统计学差异(P>0.05)。泪道塞组与倍然组FL评分分别为6.23±1.12和5.42±2.10分,差异无统计学意义(P>0.05)。结论:泪道塞在LASIK术后早期缓解干眼症状中与人工泪液具有相同的作用。

AIM:To investigate the effect of punctum plugs relieved the dry eye symptoms at the early stage after Laser in situ keratomileusis(LASIK).METHODS:Fifty-four patients(108 eyes) were treated with LASIK in our hospital.54 eyes of 27 patients received punctum plugs as treatment randomly 2 days after surgery.The other patients used artificial tear instead.Schirmer Ⅰ test(SⅠt),tear break-up time(BUT) and fluorescent staining(FL) were measured 2 weeks after surgery.RESULTS:The SⅠt in punctum plugs group was 11.90±4.20mm/5min,while 10.85±3.42mm/5min,in eye drop group.The BUT were 13.12±2.58s and 11.67±3.29s in punctum plugs group and eye drop group respectively.The FL were 6.23±1.12 and 5.42±2.10.CONCLUSION:Our results showed that there was no difference between punctum plugs group and eye drop group to relieve the dry eye symptoms at the early stage after LASIK.
