为评价激光原位角膜磨镶术治疗近视散光的准确性、稳定性及恢复速度，将ＬＡＳＩＫ手术７５２眼分为Ａ（０～－１Ｄ）、Ｂ（－１．２５～－３Ｄ）、Ｃ（－３．２５～６．５Ｄ）三组，对手术前后不同时期的散光度及轴向变化进行动态观察和统计分析。结果：术后裸眼视力≥０．５者占９７．３％，≥１．０者占８８．２％，平均１．０６±０．１８；临床散光度由术前－１．５６±０．４２Ｄ降为术后－０．５８±０．３８Ｄ，下降了６２．８％（Ｐ＜０．０１），三组病例的散光度矫正效果分别为２５．０％、７３．６％和７６．５％；裸眼视力及散光度的矫正术后第一天就基本恢复，一周后趋于稳定；循规则散光由术前的７４．３％降为２３．７％，逆规则散光由１５．６％升为６２．２％，斜散光无明显变化。结论：ＬＡＳＩＫ治疗近视散光术后视力好，准确性、稳定性高，恢复速度快，但尚有一定的欠矫率，术后有逆规则散光增多的趋势，指导手术的软件系统有待于综合考虑各种因素进一步改进
To evaluate the accuracy, stability and recovery rate of laser in situ keratomileusis for treatment of myopic astigmatism, 752 eyes were divided into A (0 ~ -1D), B (-1.25 ~ -3D), C ( -3.25 ~ 6.5D) three groups, before and after surgery at different stages of astigmatism and axial changes of dynamic observation and statistical analysis. Results: Postoperative uncorrected visual acuity ≥0.5 accounted for 97.3%, ≥1.0 accounted for 88.2%, an average of 1.06 ± 0.18; clinical astigmatism from preoperative -1.56 ± 0. 42D decreased to -0.58 ± 0.38D postoperatively, a decrease of 62.8% (P <0.01). The corrected effect of astigmatism in three groups was 25.0%, 73.6% and 76, respectively. 5%. The correction of uncorrected visual acuity and astigmatism was basically recovered on the first day after operation, and stabilized after one week. The regular astigmatism decreased from 74.3% preoperatively to 23.7%, and the reverse regular astigmatism increased from 15.6 % Rose to 62.2%, oblique astigmatism no significant change. CONCLUSION: LASIK has a good visual acuity, high accuracy and stability after myopia astigmatism. The recovery rate is fast, but there is still a certain degree of undercorrection rate. The trend of astigmatism increases with the reverse rule after operation. The software system for guiding the surgery needs to be considered comprehensively Various factors to further improve
