摘要
目的比较双面准分子激光原位角膜磨镶术（both side lasik，BSL）和准分子激光原位角膜磨镶术（Laser in situ keratomileusis，lasik）治疗高度近视眼术后高阶像差的变化。方法选择BSL和1asik两种术式对高度近视眼手术治疗61例，122只眼。其中，BSL手术30例，60只眼；lasik手术31例，62只眼。使用NIDEK公司生产的OPD—SCAN波前像差分析议，测量术前和术后一周、一个月和三个月暗室6～7mm自然瞳孔直径的波前像差。结果1BSL和lasik两组术前总高阶像差、C7、C8和C12均方根值（RMS值）比较，均P〉0．05，差异无统计学意义。2术后一周、一个月和三个月时BSL和lasik两组的总高阶像差、c7、c8和C12RMS值均较术前差异有统计学意义（P〈0．01）。3。术后一周、一个月和三个月BSL和lasik两组之间总高阶像差、C7、C8和C12RMS值比较，P值均〉0．05差异无统计学意义。结论BSL和lasik两种手术方法治疗高度近视眼，术后高阶像差增加幅度相近似。
Objective To compare the high-order aberration after both side laser in situ keratomileusis （BSL） and laser in situ keratomileusis （Lasik） operation in treating high myopia. Methods BSL and Lasik were both performed in 61 （122 eyes） patients with high myopia. Among which 30 patients （60 eyes） were randomly selected as BSL group, and 31 patients （62 eyes） were selected as Lasik group. The wavefront aberration were measured in darkroom with normal pupil at preoperatively, 1 week, 1 month and 3 months postoperatively by OPD-SCAN object aberration apparatus produced in NIDEK company. Results The root mean square （RMS） value of high-order aberration, C7, C8 and C12 in BSL group and Lasik group were not statistically significant at preoperatively （P 〉0.05）. The RMS value of C7, C8 and C12 in BSL group and Lasik group were statistically increased at 1 week, 1 month and 3 months postoperatively （P 〈0.01）. The RMS value of C7, C8 and C12 in BSL group and Lasik group were not significantly different at 1 week, 1 month and 3 months postoperatively （P 〉0.05） . Conclusions The increase of the high-order aberration after BSL and Lasik operation in treating high myopia is similar.
