摘　　要：目的 比较LASIK单区与多区切削治疗高度及超高度近视的安全性,稳定性和远期疗效。方法 高度及超高度近视患者67例（134只眼）,按术前屈光状态（等效球镜）分为A组（-6.00～-9.00D）70只眼,其中单区切削组40只眼,多区切削组30只眼;B组（-9.00～-13.00D）64只眼,其中单区切削组28只眼,多区切削组36只眼。术后1天、1周、1、3、6及12个月随诊并分别记录手术前后裸眼视力和屈光度、手术切削时间和深度,术前及术后6个月和12个月角膜厚度。结果 术后视力、屈光度、角膜厚度均于术后6个月稳定。随术前屈光度增加,术中切削时间和深度增加;术后视力降低,欠矫或回退增加;术后角膜厚度降低。同单区切削相比,多区切削术后屈光度较高,但术后视力并无差别,且切削时间较短,切削深度较浅、术后角膜较厚。结论 对于高度和超高度近视患者,多区切削能在获得相同远期疗效的同时,保证安全和稳定。因此对于高度超高度近视特别是角膜较薄患者,值得考虑采用多区切削。Objective To compare the difference in safety, stability and long-term therapeutic effect on high myopia between single-zone lasik and multi-zone lasik. Method 67 patiets（134 eyes）with high and severe myopia were divided into two groups according to pre-operation diopter.A：（-6.00D - -9.00D）70 eyes, among them 40 eyes were treated with single-zone lasik,30 eyes were treated with multi-zone lasik.B：（-9.00D - - 13.00D）64 eyes,among them 28 eyes were treated with single-zone lasik,36 eyes were treated with multi-zone lasik.All eyes were checked at 1 day,1 week,1, 3, 6. 12 months after operation noting the uncorrected visual acuity and the best corrected visua acuity and diopter.Analyzing the changes of visual acuity and diopter before and after operation,simultaneously noting the pre-operation corneal thickness and on the 6,12months after operation,operation time and operation depth.Result 6months after operation,the increase of pre-operation diopter,the post-operation visual acuity and corneal thickness decrease while the diopter, operation time and depth ascend.Though the post-operation diopter is higher in multi-lasik group,there has no difference on post- operation visual acuity between single-zone and multi-zone lasik,but the latter have shorter operation time, lower cutting depth and higher post-operation corneal thickness.Conclusion To patient with high and severe myopia,multi-zone lasik acquire same therapeutic effect,can simultaneously guarantee the safety and stability. For those who have high or severe myopia with extra thin cornea, it＇s valuable to employ multi-zone lasik.
