角膜表面规则性指数(SRI)与角膜表面非对称性指数(SAI)呈正相关，而且近视眼的散光度与其屈光度、SAI呈正相关。
The surface regularity index (SRI) was positively correlated with surface asymmetry index (SAI), and the astigmatism was positively correlated with dioptre and SAI in myopia.
结论双眼的全眼和角膜散光在轴向方面都具有同质性，并且具有对称或近似对称趋势。
Conclusion the total astigmatism axis and the binocular astigmatism axis of cornea have the characteristic of homogeneity, also the trend of symmetry.
