摘　　要：目的评价准分子激光原位角膜磨镶术（laserinsitu keratomileusis；LASIK）治疗近视性屈光参差性弱视的临床疗效。方法用LASIK手术矫正8位近视性屈光参差性弱视患者，比较手术前后屈光不正的度数和立体视锐度的改变，并将术前的最佳矫正视力和术后第1天，第3天，第10天的裸眼视力以及6～9个月随访的裸跟视力和最佳矫正视力进行比较和分析。结果术前屈光度数高眼的屈光不正的等效球镜平均为（-10．06±1．50）D，术后该眼屈光不正的等效球镜平均为（0．19±0．32）D。手术前后立体视锐度差别有统计学意义（z=-2．207，P=0．027）。术前屈光度数高眼矫正视力和术后该眼矫正视力相比，差别有统计学意义（F=11．431；P=0．000）。结论LASIK手术能安全，有效地减少近视性屈光参差，提高患者的视力和立体视功能。Objective To evaluate the clinical effect of laser in situ keratomileusis （LASIK） for myopic anisometropic amblyopia. Methods LASIK was performed in 8 myopic anisometropic amblyopia patients, the mean preoperative and postoperative spherical equivalent refraction and stereo acuity were compared. Preoperative best spectacle corrected visual acuity and postoperativelday, 3day, 10day uncorrected visual acuity and 6-9month following-up uncorrected visual acuity and best spectacle corrected visual acuity were compared and analyzed. Results The mean preoperative spherical equivalent refraction was -10.06D± 1.50D, after LASIK,the mean postoperative spherical equivalent refraction was0.19D± 0.32D. The improvement in stereo acuity was statistically significant （z =-2.207,P =0.027）.On general,the improvement of postoperative uncorrected visual acuity was statistically significant （F =11.431 ;P =0.000）.Conclusion Laser in situ keratomileus can reduce myopic anisometropia safely and effectively. It can improve visual acuity and stereo acuity also.
