  • 摘要: 本文提出了一种新的角膜面形分析方法,不仅消除了角膜本体厚度对塑形后角膜面形分析的影响,同时也能体现塑形后角膜的不对称性。在角膜前表面高度数据分析中引入基准参考面,以消除角膜本体厚度的影响,进而将塑形后的角膜前表面划分为光学区、转换区和边缘区。分析表明,角膜塑形后的光学区口径为(1.9±0.27) mm,曲率半径为(8.32±0.38) mm;转换区口径为(6.56±0.38) mm,曲率半径为(7.48±0.55) mm;边缘区的曲率半径为(10.49±1.83) mm。角膜塑形后的转换区水平方向屈光能力小于竖直方向的屈光能力,鼻侧屈光能力大于颞侧屈光能力,上侧屈光能力大于下侧屈光能力。利用所得参数建立半定制化的眼模型,对眼模型进行分析,结果表明:角膜塑形后周边呈近视性离焦,各方向的离焦呈非对称性分布,符合临床表现。
