  • 简介:目的分析比较角膜地形图与散瞳检影两种方法所测得散光及与近视度数关系。方法采用角膜地形图对290准备行LASIK手术近视眼进行检查,同时采用散瞳检影法检查记录近视度数及散光并对两种方法所得数据进行比较分析。结果两种方法在散光轴向上无显著性差异(P>0.5);而在散光度数方面有非常显著差异(P<0.01)。角膜地形图检查及检影法所测得散光度数均与屈光度增高成正比。结论角膜地形图能快速而准确地提供角膜屈光状态指标;全眼散光仍应以散瞳检影后患眼接受度数和散光轴作为标准;散光度数均与屈光度增高成正比。

  • 简介:质量是个难以描述及定义概念。人们对质量评定各有不同见解。拿出租车旅行来打个比方。你如何评定旅行质量?你评定时基于司机是否有礼貌还是车子豪华程度?或者以你安全到达目的地为标准?如果让你司机来评价同样场旅行质量,他们可能认为旅途中没有抛锚或没有被交通事故耽搁就是好。评定质量有很多不同标准,以那点为准取决于你角色。
