摘　　要：目的评价小光斑飞点扫描准分子激光系统应用于准分子激光角膜原位磨镶术(Lasik)治疗低、中、高度近视的效果。方法将本院眼科2002年7月至2004年3月近视患者1238例(2418眼)按术前屈光度分3组:I组(-0.75^-6.00)D,Ⅱ组(-6.25^-10.00)D,Ⅲ组(-10.25^-21.00)D。采用德国Schw ind公司生产的Esiris第6代小光斑飞点式准分子激光系统和法国Moria公司生产的电动旋转式角膜板层刀进行Lasik手术。术后随访1年,对视力、屈光度、偏中心情况及术后并发症进行随诊分析。结果术后第1天裸眼视力达1.0以上分别为91.1%、84.9%、52.0%;术后3个月时裸眼视力1.0以上的分别为96.2%、93.0%、84.2%;术后6个月时裸眼视力≥术前最佳矫正视力者占91.7%。所有患者屈光度在术后1~3个月时基本稳定。结论小光斑飞点扫描准分子激光治疗近视眼术后视力恢复快,稳定快,无偏心切削、中心岛形成及不规则散光。Objective To evaluate the effectiveness and safety of laser in situ keratomileusis （Laslk） on low, moderate and high myopia using a scanning spot excimer laser. Methods 1238 patients （2418 myopia eyes） were divided into 3 groups： group Ⅰ（ -0.75 - -6.00） D, group Ⅱ （ -6.25 - 10. 00） D, group Ⅲ （ -10.25 - -21.00）D, All the patients were followed up for 1 year in visual acuity, refractive status, complication and eccentric ablation. Schwind Esiris, a scanning spot excimer laser was used. The flap was performed with the Moria microkeratome. Results 91.1% , 84.9% and 52.0% had vision of 1.0 or better in the 3 groups one day after operation; 96.2% , 93.0% and 84.2% had vision of 1.0 or better in the 3 groups at 3 months. The rate of postoperative uncorrected visual equal or better than the preoperative corrected visual acuity was 91. 7% at 6 months. Refractive degree was stable from 1 to 3 months. Conclusions The results of myopic treatment by using a scanning spot excimer laser are satisfactory. Uncorrected visual acuity recovers fast and no eccentric oblation, central islands formation and irregular astigmatism are found.
