Results: The contrast between the changes in the corneal topography one to two weeks after operation and before the operation shows that astigmatism progressed in the direct astigmatism group while diminished in the inverse astigmatism group. 结果:手术后1~2周角膜地形图变化与手术前相比循规性散光组散光增加,经统计学处理差异有显著性,逆规性散光组术后散光较术前减少,差异有显著性。
Conclusion: Astigmatic axis can be changed with growth of the age and distributed as inverse astigmatism. 结论:散光轴向可随年龄增长而改变,并呈逆规性散光状态的变化。
With the growth of ages, the inverse astigmatism was increasing. Most of the astigmatic axes over 40 years old were distributed as inverse astigmatism. 随着年龄的增长,逆规性散光的比例增高,40岁以上年龄组散光眼的散光轴向大多呈逆规性散光分布。
