摘要
对４４５例（８５５只眼）进行只矫正近视而未同时作散光矫正的准分子激光角膜切削术，术后观察３～１２个月。结果表明，无论观察３个月、６个月、１２个月术后散光增加病例明显少于散光减少的病例。同时与ＲＫ术后散光变化情况比较，有极显著性差异，明显优于术后有散光增加趋势的ＲＫ术。散光的改变与手术中眼球转动、停机、激光切削中心与光学中心偏离。
cases(855 eyes) treated with PRK only for myopia were followed up for 3～12 months The results showed that the number of cases with an increase in astigmatism was less than that of with a decrease in astigmatism Compared with the change of astigmatism after RK,the result was better and there was a statistical significant difference (p<0 01) We found that change of astigmatism was related to eyes moving durning the operation,the stop of machines working,the deviation of laser center from optical center,and the instability of laser energy
