近视眼角膜屈光力及眼轴的测定分析

应用ＳＹＳＴＡＴ软件处理数据，测量２７６例（５２３只眼）近视眼的角膜屈光力及眼轴，并对近视眼的角膜屈光力与散光，近视程度与屈光力、眼轴的关系，以及近视的成因进行分析。结果表明：垂直径角膜屈光力明显大于水平径角膜屈光力；高度和超高度近视组的垂直径角膜屈光力较低、中度组者值高；在不同屈光度组之间，眼轴的差异非常显著；近视程度与角膜屈光力和眼轴有一定的关系。由此证明，角膜屈光力和眼轴为近视形成的两个主要

Examination aud analysis on keratometry and axis of myopia

In this study, we applied SYSTAT software package to deal with the data,measured the keratometric values and axes of 276 patients with myopia(523 eyes),analyzed on the data of ker-atometry and astigmatism,correlations between the myopic degree and keratometric value and between the former and length of axis,and pathogenesis of myopia. The results revealed that the vertical corneal refractive power was stronger than the horizontal value,the vertical corneal refractive power in high and superhigh myopia was greater than that in mild and medium myopia,the axial lengths are significantly different among mild,medium, high and superhigh myopia(P<0.01),and the myopic degree is corre-lated with the keratometric value and axial length.We can conclude that keratometry and axis are two main factors for the formation of myopia.
