The total astigmatism was well correlated with cornea astigmatism.
角膜散光与总和散光呈显著正相关；
When the cornea curves or flattens unevenly, the result is astigmatism, which disrupts focus of near and distant vision.
散光是当角膜变弯或者变平时表面不平坦，影响视近、视远时的聚焦。
Astigmatism: distorted vision resulting from an irregularly curved cornea, the clear covering of the eyeball.
散光：因角膜(覆盖眼球的一层透明膜)不规则弯曲而引起的影象变形。
Astigmatism occurs if the cornea is shaped like a rugby its curvature is not uniform. As a result horizontal lines are focused to a different point from vertical lines.
若角膜呈榄球形状，即其弧度呈不规则，水平光线将聚焦在和垂直光线不同的焦点，这便是散光。
Astigmatism occurs due to the irregular shape of the cornea or the lens inside the eye.
散光是由不规则的角膜或晶状体所引起的。
In astigmatism, the surface of the cornea or lens has a somewhat different curvature in one direction than another.
在散光中，同一方向上，角膜和晶状体表面的曲率是不同的。
It appears eyelids do play a part in determining the shape of the cornea. One explanation is that pressure from the eyelids is involved in the cause of corneal astigmatism.
看起来眼睑在决定角膜形状方面起着一定作用，这种现象的一种解释就是眼睑与角膜散光有关。
Astigmatism is caused when the cornea is shaped irregularly like a football.
散光是由于角膜时，形状像一个足球不定期。
Maintaining smaller vertical primary coma and correcting spherical aberration completely for myopia and myopic astigmatism may be the best choice for customized cornea laser ablation surgery.
对欲行个体化角膜切削的近视及近视散光患者，保留较小的垂直彗差而完全矫正球差可能有助于视觉质量的提高。
Conclusion the total astigmatism axis and the binocular astigmatism axis of cornea have the characteristic of homogeneity, also the trend of symmetry.
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.
