ALASIK,WLASIK和SLASIK术后疗效的对比分析

acuity,diopter,offer Q value,high order aberration refraction,also postoperative glare were noted.The ablation zone was from 6.0 to 7.0mm.Wavefront aberrations were analyzed for 6.0mm pupil zone.Refraction were observed before and 1,3 and 6 months after surgery. To compare and analyze the changes and relationships of index.RESULTS: At the 6 months after surgery, ALASIK group and WLASIK showed the better acception than SLASIK group, difference was statistical significant（P<0.05）. In middle group, the visual acuity of WLASIK was better than the others，and the difference was statisticaly significant (P<0.05).In midlle group，the asphericity of ALASIK group was the more decreased obviously than WLASIK group and SLASIK group,the coma was increased in WLASIK and spherical aberration was decreased obviously in ALASIK,and the difference was statisticaly significant（P<0.01）.CONCLUSION: ALASIK, WLASIK and SLASIK are effective on correcting myopia and astigmatism safely
