应用ＴｏｍｅｙＴＭＳ－２ＴＭ型角膜地形图对高度、中低度近视和正视眼进行角膜表面屈光力和形态检查，结果显示高度近视眼角膜中央陡度比中低度近视眼高，近视眼角膜屈光力比正视眼高，高度近视眼角膜表面规则系数和不对称指数比正视眼和中低度近视眼高，提示这可能是造成高度近视眼最佳矫正视力下降的原因，其结果可为屈光性角膜手术提供解剖依据。 The use of TomeyTMS-2TM corneal topography on the high and low myopia and corneal surface corneal surface refractive power and morphology examination showed that the high myopia corneal central steepness than low and medium myopia high myopia corneal refractive power than the eyelid High and high myopia corneal surface of the coefficient of regularity and asymmetry index than the eye and low to moderate myopia, suggesting that this may be caused by the best corrected visual acuity in high myopia decline, the results can be provided for refractive corneal surgery Anatomy basis.
