摘　　要：目的了解近视眼患者行准分子激光原位角膜磨镶术准分子激光原位角膜磨镶术术后干眼症状及相关指标的变化。方法48例(96眼)近视眼患者行准分子激光原位角膜磨镶术手术,分别观察术前、术后1周、1个月、2个月、3个月的干眼症状,包括干涩感、异物感等,并行角膜荧光素染色检查、泪膜破裂时间测定及泪液分泌试验。结果术后1周至2个月干眼症状较术前明显加重;术后1周角膜荧光素染色着色眼数较术前明显增加;术后1周、1个月、2个月泪膜破裂时间均较术前缩短;术后1周、1个月、2个月泪液分泌量较术前明显减少。结论干眼症是准分子激光原位角膜磨镶术术后的常见并发症,临床应积极采取预防措施,以使准分子激光原位角膜磨镶术术后干眼症的发生率和严重程度降到最低。Objective To evaluate the symptoms and corresponding indexes of dry eye after laser in situ keratomileusis （Lasik） in myopic eyes, Methods Ninety six myopic eyes were performed Lasik, The eyes were observed for subjective complaints of dry eye,fluorescein staining （FI）,Schirmer＇ s I test,tear break- up time（BUT） preoperatively and 1 week, 1 month,2 months,3 months postoperatively, Results The subjective complaints of dry eye were more severe after the operation. F Ⅰ staining dots were more concentrated at 1 week postoperatively. There were obvious decreases in BUT at 1 week, 1 month and ：2 months postoperatively relative to the preoperative level. The Schirmer＇ s 1 test result was lower at 1 week, 1 month and 2 months after Lasik. Conclusions Dry eye is common after Lasik in myopic eyes. It＇ s necessary to get some preventive and therapeutic methods to reduce the hurt.
