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 safety and efficacy of laser subepithelial keratomileusis (LASEK) in the treatment of myopic astigmatism. Methods 91 eyes (182 eyes) of myopic astigmatism patients underwent LASEK surgery. The patients were followed up for 12 months. The changes of visual acuity, refraction, astigmatism and axial astigmatism were observed. Results After 12 months of follow-up, uncorrected visual acuity (BCVA) ≥61.5%, postoperative astigmatism within ± 1.00 D, residual astigmatism average -0.24 D, astigmatism correction 74.8% Astigmatism axis preoperative deflection 23 °. The results of preoperative and postoperative paired t test, P <0.01, there are significant differences between the two. Conclusion LASEK is a safe, reliable and predictable myopic astigmatism.
