摘要
目的 比较Q值引导的机械刀制瓣前弹力层下角膜磨镶术（OUP-SBK）和飞秒激光制瓣SBK （Femto-SBK）2种手术方式对术眼角膜像差的影响.方法 回顾性病例对照研究.138例患者（276眼）根据制瓣方式不同分为2组：OUP-SBK组77例,其中按术前等效球镜度（SE）分为低度近视组17例（SE≤-3.00 D）,中度近视组29例（-3.00 D＜SE＜-6.00 D）,高度近视组31例（SE≥-6.00 D）;Femto-SBK组61例,其中低度近视组13例,中度近视组24例,高度近视组24例.均采用Q值引导的准分子切削模式手术,分别于术前及术后1、3、6个月测量术眼角膜的总高阶像差、球差、水平彗差、垂直彗差、水平三叶草和斜向三叶草数据,采用方差分析和独立样本t检验进行统计分析.结果 术后低度近视组角膜总高阶像差、球差、垂直彗差高于术前（F=32.4、14.6、4.6,P＜0.01）;中度近视组角膜总高阶像差、球差、水平彗差、垂直彗差、水平三叶草术后高于术前（F=40.9、22.5、34.0、2.7、24.4,P＜0.05）;高度近视组角膜总高阶像差、球差、水平彗差、垂直彗差OUP-SBK组明显高于Femto-SBK组（F=15.4、3.9、10.4、4.8,P＜0.05）.结论 对于高度近视患者,飞秒激光制瓣较角膜刀制瓣产生的像差少,能给患者提供更优质的视觉质量。
Objective To compare the changes in aberrations following microkeratome sub-Bowman＇s keratomileusis （SBK） （OUP-SBK） and femtosecond laser SBK （Femto-SBK） with customized Q-factor.Methods This was a retrospective clinically controlled study.One hundred thirty-eight patients （276 eyes） were divided into two groups： one group （77 cases） was treated with Moria One-Plus SBK and the other group （61 cases） was treated with femtosecond laser SBK.The former group was divided into subgroups with spherical equivalents that included low myopia （17 cases） （≤-3.00 D）, moderate myopia （29 cases） （〉-3.00 D, 〈-6.00 D） and high myopia （31 cases） （≥-6.00 D）.The latter group included low myopia （13 cases） （≤-3.00 D）, moderate myopia （24 cases） （〉-3.00 D, 〈-6.00 D） and high myopia （24 cases） （≥-6.00 D）.Both groups had customized Q-factors.Total higher order aberrations （HOA）, spherical aberrations （C40）, horizontal coma （C31）, vertical coma（C3-1）, horizontal trefoil （C33） and oblique trefoil （C3-3） were measured preoperatively and 1 month, 3 months and 6 months after surgery.Data were analyzed using repeated measured ANOVA, an independent samples t test.Results After surgery for the low myopia group, total corneal HOA, C40 and C3-1 were increased compared to preoperation （F=32.4, 14.6, 4.6, P〈0.01）;for the moderate myopia group, the total corneal HOA, C40, C31, C3-1, C33 was increased compared to preoperation （F=40.9, 22.5, 34.0, 2.7, 24.4, P〈0.05）;for high myopia, the total corneal HOA, C40, C31 and C3-1 were better for Femto-SBK than for OUP-SBK （F=15.4, 3.9, 10.4, 4.8, P〈0.05）.Conclusion For patients with high myopia, the increase in the degree of aberrations after Femto-SBK is smaller than that after OUP-SBK.Femto-SBK can provide patients with better visual quality.
