散光轴位

柱面散光轴位角进行手动测量，数码显示的数字化屈光度测量仪。本仪器采用特殊的处理电路，消除了外来噪声产生的误触发脉冲及输出错误积累而引起的位置偏移。

This instrument has a rotary encoding and raster and it has a special processing circuit not only eliminating trigger pulse case by noise but also clearing up position accumulates error.

矫正散光的效果：手术后12个月时散光度矫正准确率C组和D组分别为70%和95.7%，散光轴位符合率分别为78.3%和100%。

The accuracy rate of astigmatism correction in the 12th month after operation in group C and group D was 70% and 95.7%, respectively. The coincidence rate of the astigmatism axis position was 78.3% in group C and 100% in group D.

将手术性散光的度数及轴位变化进行矢量分析，可综合评价手术致角膜屈光状态的改变；

Vector analysis can systemically evaluate surgically induced astigmatism.

结果术后2～3周△Sim K值增加，P<0.05，正柱镜散光轴位改变与切口方向有关。

Results We found that △ Sim K increased 2~ 3 weeks post-operation, P < 0 05.The axis of astigmatism was related to the direction of incision.

结论LASIK联合可蚀盘矫治复性近视散光，散光度矫正准确率高，散光轴位符合率高，散光度高矫正效果更好。

Con-elusion LASIK combined with erodible disc for the treatment of compound myopic astigmatism can result in high accuracy of astigmatism correction, high coincidence rate of astigmatism axis position and satisfactory correction effect.

术后3月与术前比较，散光度数与轴位均无统计学意义改变。

No significant difference was found between pre-operation and 3 months post-operation.
