摘　　要：目的对于薄角膜高度近视患者,通过临床研究摸索出适合该人群的最佳手术方式。方法 2007年6月至2008年6月我院行近视眼激光手术的薄角膜高度近视患者76例(149只眼),随机分为两组,组1使用MoriaM290一次性刀头行准分子激光原位角膜磨镶术(LASIK组):45例(88只眼);组2行准分子激光上皮下角膜磨镶术(LASEK组):31例(61只眼)。术后1d、1周、半个月、1个月、3个月、6个月观察症状、裸眼视力、验光、裂隙灯、眼底镜、眼压、角膜厚度及角膜地形图。结果术后第7天,组1无一眼出现角膜刺激症(0%)。组2仍有5只眼出现(8.2%)。术后第1天,所有术眼均有不同程度疼痛、异物感、畏光流泪。角膜Haze:组1:无一眼出现,组2:所有术眼仅见轻微Haze,多数眼表现为0或1级的Haze,两组比较有显著性差异(P<0.05)。术后1周、术后1个月两组视力差异有统计学意义(P<0.05);术后3个月及6个月两组视力差异无统计学意义(P>0.05)。术后各期角膜厚度比较均无统计学意义(P>0.05)。结论 MoriaM2型90刀头在LASIK治疗高度近视和薄角膜的患者中具有较好的安全性和疗效性,可成为屈光度数高、角膜相对薄患者的首选的安全稳定的术式。Objective Comparative study of myopia laser surgery in critical corneal thickness patients,and explore the best suitable surgery for the patients.Methods High myopia 76 cases of 149 eyes,from June 2007 to June 2008 in our hospital,with thinner corneas and were randomly divided into two groups,group 1（using one-time MoriaM290 Blade LASIK group）：45 cases of 88 eyes;Group 2（LASEK group） 31 cases of 61 eyes;oberserve including symptom,uncorrected visual acuity,corneal thickness and corneal topography,etc,all cases were observed 1month to 6 months after surgery.Results LASIK induced less pain and hase than LASEK in the early postoperation.There was significant difference in the whole average vision in the early postoperation（P 0.05）,but there was no significant difference in the vision,also cornea thickness postoperation between two groups（P 0.05）.Conclusion MoriaM2 90 LASIK can be a better safety and effective surgery in critical corneal thickness patients with high myopia.
