散光度数是对眼睛进行散光测试所得出的散光程度的数字表示。如某一子午线屈光力不等就会出现散光.看线条出现深浅不一,粗细不一，散光表就是利用这样的原理设计的。
结论像差随屈光度数的增大而增大，散光度数对高阶像差有明显的影响。
Conclusion aberrations increase with an increase of refractive power in diopters and astigmatism is significantly related to the high aberrations.
与传统角巩膜缘切口比较，术中眼压维持稳定，术后手术性角膜散光度数小。
Tunnel incision can make the surgery process easier and induce corneal astigmatism smaller.
对全部术眼分别应用显然验光法和角膜曲率法观察术后1周、1、2、3个月球镜和散光度数的变化。
All patients were refracted and examined with keratometry preoperatively, 1 week, 1. month, 2 months and 3 months postoperatively.
