摘　　要：目的研究高度近视合并白内障患者是否会因其高度近视巩膜病变产生额外的术源性散光。方法2016年3月至2016年12月期间,白内障患者105例(117只眼),其中单纯年龄相关性白内障63例(70只眼),年龄相关性白内障合并高度近视42例(47只眼)。两组均行经巩膜隧道切口白内障超声乳化+人工晶状体植入术。用Jaffe/Clayman矢量分析法计算两组术源性散光,Spss20.0统计学软件采用两独立样本秩检验分析两组患者术源性散光。结果两组患者术源性散光比较(P=0.418>0.05)提示两组患者术源性散光无明显差异。结论高度近视眼合并白内障患者行白内障超声乳化术,不会因其巩膜病变而产生更多的术源性散光。Objective To investigate whether high myopic patients will suffersurgically induced astigmatism（ SIA）after scleral incision cataract surgery. Methods Between March 2016 and December 2016,105 cataract patients（ 117 eyes） were included in the study. There were 63 age-related cataract patients（ 70 eyes） and 42 cataract and high myopia patients（ 47 eyes）. Both groups of patients underwent scleral tunnel incision phacoemulsification and intraocular lens implantation. Jaffe/Clayman vector analysis was used to calculate amount of SIA. Two-independent-sample ranking test（ SPSS20. 0） was used to compare the results. Results There was no significant difference in the astigmatism between the two groups（ P = 0. 418 0. 05）. Conclusions Phacoemulsification in patients with high myopia will not produce more astigmatism due to sclera incision.
