摘要： 目的观察采用波前像差引导的个体化切削准分子激光角膜原位磨镶术治疗中、低度近视的疗效。方法对24例48眼中低度近视患者行波前像差引导的个体化准分子激光角膜原位磨镶术，观察术后视力、屈光度和高阶像差，并与同期42眼的标准手术进行对比。结果个体化准分子激光手术后30d裸眼视力3眼UCVA超过术前BCVA 2行,16眼超过1行；24眼与术前相等，3眼低于术前1行，优于对照组；术后慧差减小；且术前垂直慧差与术后波前像差均方根和呈负相关。结论波前像差引导的个体化准分子激光近视矫正手术可以减小患者术后高阶像差，提高患者术后视觉质量。正确选择适应证可以提高个体化手术的效果。

Abstract: Objective To investigate the outcome of the wavefront-guided laser in situ keratomileusis(LASIK) in correcting low and midrange myopia. Methods The wavefront-guided laser in situ keratomileusis(W-LASIK) were performed on 48 eyes. The visual acuity, refraction and higher order aberration were determined pre-and post-operation, and the outcomes were compared with those of 42 eyes following standard-LASIK(S-LASIK). Results At 1 month after wavefront-guided surgery, compared with the BCVA of pre-operation, the UCVA was raised 2 lines in 3 eyes, 1 line in 16 eyes, was not changed in 24 eyes, and was decreased 1 line in 3 eyes. The outcomes were superior to those of the S-LASIK group. The coma following W-LASIK was lower than that following S-LASIK. In addition, the post-operative root mean square (RMSh) negatively related to the pre-operative vertical coma. Conclusions The wavefront-guided laser in situ keratomileusis can decrease the higher order aberration of myopia patients and increases the quality of vision.
