摘　　要：目的 :探讨准分子激光原位角膜磨镶术 (LASIK)角膜瓣蒂置于上方位与鼻侧位术后干眼症的差异。方法 :随机选LASIK手术角膜瓣蒂置于上方位 176只眼 ,鼻侧位 185只眼。分别于术后 1日、1周、1个月和 3个月测定记录泪液分泌(Schirmer 1)和泪膜破裂时间 (BUT)。结果 :手术后 1日和 3个月两组 ,Schirmer 1实验和BUT无明显差异 (P >0 0 5 ) ,术后 1周和术后 1个月两组Schirmer 1实验和BUT结果有明显差异 (P <0 0 5 )。旋转刀组术后 1周和 1个月分别有 4 6只眼 (占2 6 1% )和 6 8只眼 (占 38 6 % )符合干眼症的诊断 ,而平推刀术后 1周和 1个月分别有 12只眼 (占 6 5 % )和 38只眼 (占2 0 5 % )符合干眼症的诊断。结论Objective:To evaluate the effect of position of corneal cap stalk on the occurrence of dry eye syndrome after LASIK.Method:LASIK were done in 185 patients (361 eyes),aged 18～32 year,with myopia (-2 50D～-11 75D) and astigmatism (-3 50D) randomly with rotating microkeratome (176 eyes) or oscillating microkeratome (185 eyes).The stalk of corneal cap was on the superior cornea in the rotating group,while it was on the nasal cornea in oscillating group.Postoperatively,patients were checked at 1 day,1 week,1 month and 3 month.The outcomes of Schirmer 1 and BUT of 2 groups were compared and analysed.Result:There were no marked differences of the changes of Schirmer 1 and BUT between these 2 groups(P>0 05)at 1 day and 3 month postoperatively,but at postoperative 1 week and 1 month,the incidences of dry eye symptom in the rotating microkeratome group were 26 1% and 38 6% respectively while in the oscillating group being 6 5% and 20 5%.The difference was significant stastically between these 2 groups(P<0 05).Conclusion:The incidence of dry eye syndrome in nasal stalk(oscillating)group is lower than in the superior stalk(rotating)group.
