摘　　要：目的 前瞻性研究角膜波面像差引导准分子激光原位角膜磨镶术（ORK-W）治疗近视临床效果。方法 将球镜-8．00D以下，柱镜0．00D-3．00D的近视患者随机分成2组，实验组36例72眼行角膜波面像差引导准分子激光个体化切削（ORK-W），对照组30例（60只眼）行常规LASIK。观察术后1m裸眼视力、残余屈光度，角膜波面像差中的慧差、球差及总像差均方根RMS增加值，对比敏感度的改变，满意度等指标。结果 术后裸眼视力、残余屈光度和满意度两组比较差异无统计学意义（P〉0．05）；但实验组角膜波面像差（慧差、球差、均方根RMS）的增加均较对照组明显小，两组差异有统计学意义（P〈0．05），对比敏感度的改善较对照组也明显的好，两组差异有显著统计学意义（P〈0．01）。结论 角膜波面像差引导准分子激光个体化切削（ORK-W）可以减少术后角膜波面像差的增加，尤其减少慧差增加效果更明显，明显改善视觉质量。Objective Prospective study on the clinical effect for myopia treated with ORK-Corneal Wavefront.Nethods The short-sighted patients （volumes for sphere ,below-8.00 D, volumes for cylinder 0.00D-3.00D） were randomly divided into two groups. Experimental Group ：36 cases （72 eyes）, treatment with ORK-Corneal Wavefront （Control Group） 30 cases （60 eyes） ,treatment with regular Lasik; observed the naked vision ,remained refractive degree ,increas volumn of Corneal Wavefront（Coma. Sph Ab and RMS） after a month of operation, Compared the contrast sensitivity and satisfication with two groups. Results Naked Vision after the operation, remained refractive degree and satisfication ,compared between two groups, There was no difference （P〉0.05）,but Corneal Wavefront （Coma. Sph Ab and RMS） in Experiment Group increased less than in Control Group（P〈0.05）,the contrast sensitive is better（P〈0.01）.Conclusion ORK-W Corneal Wavefront may decrease Corneal Wavefront increasing, especially decrease Coma, It is obvious to perfect the vision quality.
