LASEK治疗近视散光的临床疗效观察

Clinical Analysis of Laser Assisted Subepithelial Keratomileusis for Correction of Myopic Astigmatism

目的探讨准分子激光上皮下角膜磨镶术(LASEK)治疗近视散光的安全性和有效性。方法对91人(182眼)近视散光患者进行LASEK手术治疗。随访12个月,观察手术后的视力,屈光度,散光及其散光轴位的变化。结果术后随访12个月,裸眼视力≥术前最佳矫正视力(BCVA)者占61.5%;所有患眼术后散光在±1.00 D以内,残留散光平均为-0.24 D,散光矫正74.8%,散光轴较术前偏斜23°。术前与术后结果行配对t检验,P<0.01,二者存在显著差异。结论准分子激光上皮下角膜磨镶术(LASEK)治疗近视散光预测性佳,安全可靠。

Objective To investigate the effectiveness and safety of laser assisted subepithelial keratomileusis(LASEK) for myopic astigmatism.Methods LASEK were run on 182 eyes of 91 patients with myopic astigmatism.All were followed for 12 months.Front and back treated visual acuity,refraction,astigmatism and axis of astigmatism were observed.Results The visual acuity at 12 month after operation wasn't worse than the best corrected visual acuity(BCVA) before operation in 112 eyes(61.5%).The refraction degree after operation was less than ±1.00 D in all the eyes.The average residual astigmatism was-0.24 D,the astigmatism dropped 74.8%.The axis was changed about 23°.The result after operation was significantly better than that before operation(paired t-test,P<0.01).Conclusion LASEK had good stability and predictability,and it was an effective method for myopic astigmatism.
