【摘要】 目的　观察准分子激光原位角膜磨镶术 ( laser in situ keratomileusis,L ASIK)治疗高度近视的临床效果。方法　将行 L ASIK手术的 2 5例 4 8只眼按屈光度 (等值球镜 ,下同 )分为 A组 (屈光度为 - 6.0 0～ - 9.75 D)和 B组 (屈光度为 -10 .0～ - 2 0 .0 D) ,术后进行半年的随访观察。结果　术后 6个月裸眼视力≥ 0 .5和≥ 0 .8者 ,A组分别为 10 0 %、94 .73 % ;B组为 90 .4 7%、63 .15 %。术后 1、3、6个月时 2组角膜地形图前表面曲率各自无统计学差异 ( P>0 .0 5 )。术前屈光度高则手术预测性下降。结论　L ASIK手术治疗高度近视范围广 ,稳定性、安全性良好 ,术后视力恢复快 ,并发症少 ,尚需进一步观察其远期疗效更多还原

【Abstract】 Objective The study is arranged to observe the effect of LASIK for high myopia. Methods 48 eyes of 25 patients were divided into two groups: Gropu A (diopter rang from -6.0 -9.75D) and group B (diopter rang from -10.0 -20.0D). The following time after operation was more than 6 months. Results The acuity visual ≥0.5 and ≥0.8 at 6th month after operation in group A and group B were 100%, 94.73% and 90.47%, 63.15% respectively. There was no significant difference in two groups in topograph of anterior corneal surface curvature between 1,3,6 month respectively ( P >0.05). Conclusion LASIK for high myopia is stable safe with satisfactory acuity visual results and less complication.更多还原
