小光斑飞点扫描准分子激光治疗近视的临床观察

Laser in situ keratomileusis for myopia and astigmatism using a scanning-spot excimer laser system

目的:评价小光斑飞点扫描准分子激光系统用于LASIK手术治疗近视的疗效。方法:采用鹰视ALLEGRTTOWAVEFRONT准分子激光扫描仪及法国MORIACB角膜切削刀为2 0 2例、396眼行准分子激光治疗。屈光度为- 0 .75D～- 14 .5 0D。随访术后超过3个月的患者。观察分析视力及屈光度的变化。结果:术后第1天裸眼视力在0 .5、0 .8、1.0以上者分别为98.9% (392眼)、90 .4 % (35 8眼)、75 % (2 97眼)。术后第1、3月裸眼视力>1.0的分别为88.1% (349眼)、91.9% (36 4眼)。无严重术后并发症发生。结论:小光斑飞点扫描准分子激光系统行LASIK手术治疗近视的临床效果较好。

Objective: To evaluate the therapeutic effect of laser in situ keratomileusis(LASIK) for myopia and astigmatism using scanning-spot excimer laser.Method:202 patients(396 eyes) with myopia from -0.75D to -14.50D were performed LASIK, followed up for 3 months,and observed the changes in visual acuity and refractive diopter.Results:On the first day after surgery ,the uncorrected visual acuity >0.5,0.8,1.0 was in 329 eyes(98.9%),358 eyes(90.4%),297eyes(75%),respectively;the uncorrected visual acuity >1.0 of the lst,3rd month after surgery was in 349 eyes(88.1%),364 eyes(91.9%)respectively.No serious complications occurred after surgery.Conclusion: Scanning-spot laser system is satisfactory for myopia with less complications.
