2、不同分成2组:Topography组(角膜地形图引导的个性化FS—LASIK,22例44眼)及Wavefront组(波前像差优化的FS.LASIK,22例43眼)。Topography组应用WavelightTopolyzer角膜地形图仪采集角膜地形图数据。术后6个月,对2组视力、屈光度、角膜不规则指数、激光切削的居中性及角膜波前像差采用独立样本t检验进行比较。结果术后6个月,2组间裸眼视力(UCVA)及最佳矫正视力(BCVA)的差异均无统计学意义,无一例出现术后BCVA低于术前。术后2组间球镜度、柱镜度及等效球镜度差异亦无统计学意义
3、。Topography组患者术后角膜表面变异指数(ISV)(39.9+13.0)低于Wavefront组(44.9±12.2),差异有统计学意义(仁一2.296,P<0.05),2组术后ISV均较术前增加(t=5.216、7.870,P<0.05)。Topography组患者术后平均切削偏心量[(0.24±0.29)mm]低于Wavefront组[(0.29±0.31)mm],但2组间差异无统计学意义(仁~1.005,P>0.05)。术后6个月,Topography组角膜水平彗差(Z31)及球差(Z40)【(一0.166±0.357)
