摘要
目的：为探讨正视眼角膜表面形态和屈光力。方法：８３只正视眼用ＴｏｍｅｙＴＭＳ－２ＴＭ型角膜地形图检查角膜表面形态和屈光力。结果：①绝对等级全角膜有２～５种颜色，屈光力有轻微的变化；②角膜中央屈光力为４３．８５４±１．３２１Ｄ，Ｓｉｍｋ值为４４．１４２±１．３４２Ｄ，平均屈光力（ＡＣＰ）为４３．００７±１．４７３Ｄ，角膜表面规则系数（ＳＲＩ）为０．２４１±０．２１３，角膜表面不对称系数（ＳＡＩ）为０．３２１±０．１３０，不规则散光指数（ＩＡＩ）为０．３５７±０．００６。结论：本文检查的国人正视眼角膜表面形态和屈光力数值，可为屈光性角膜手术提供解剖依据。
Objective:To evaluate the corneal surface shape and its refractive power in normal eye.Methods:The corneal surface shape and refractie power were examined with Tomey TMS 2 corneal topography in 83 normal eyes.Results:The cornea had 2 to 5 different colors in absolute scale and the refactive power had some difference.The refractive power of central cornea was 43.854 ±1.321D, simulated keratoscope was 44.142±1.342,average corneal power was 43.007± 1.473 ,surface asymmetry index was 0.321±0.130,irregular astigmatic index was 0.357± 0.006 .Conclusions:The data of corneal surface shape and refractive power in Chinese normal eyes might give anatomic foundation for corneal refractive surgery.
