摘要
目的探究不同角膜屈光手术后高阶像差（HOA）的特征性变化。方法选取我院2015年6-12月收治的120例236眼近视及近视散光患者,其中行LASIK（准分子激光原位角膜磨镶术）37例73眼（A组）,行FS-LASIK（飞秒激光制瓣的LASIK）40例78眼（B组）B组,行FLEx（全飞秒激光FLEx）43例85眼（C组）,对比三组手术前后1mo的角膜HOA。结果手术前后三组HOA相比,差异有统计学意义（P〈0.05）;A、B两组与C组相比,差异有统计意义（P〈0.05）。结论不同角膜屈光手术后HOA均明显增加,而FLEx术因切口影响,未表现出明显优势。
Objective To investigate the characteristic changes of high-order aberration（HOA） after different corneal refractive surgeries. Methods 120 cases of patients with 236-eyes myopia and myopic astigmatism admitted into our hospital from June 2015 to December 2015, including 37 cases of 73-eyes received LASIK（A group）, 40 cases of 78-eyes received FSLASIK（B group）, 43 cases of 85-eyes received FLEx（C group）, compared 1 mo of cornea of HOA before and after surgeries of three groups. ResultsComparing HOA of three groups before and after surgeries, there was statistical significance（P〈0.05）, The vertical coma aberration of A and B groups, compared with that of C group, there was statistical significance（P〈0.05）. Conclusion HOA is increased significantly after different corneal refractive surgeries, but FLEx surgery does not show obvious advantage because of the influence of incision.
