摘　　要：目的探讨准分子激光原位角膜磨镶术(LASIK)前、术后角膜厚度的变化,计算出每一个屈光度近视实际切削角膜的厚度,进行术前预算患者角膜厚度的足与不足,筛选患者。方法对200例(400只眼)行LASIK手术的患者术前及术后半年以上追踪观察角膜厚度的变化。结果200例LASIK后角膜中央厚度术后6个月趋于稳定,每一个屈光度近视实际切削角膜约13.20μm。结论LASIK原位角膜磨镶术治疗近视眼安全可靠。Objective To investigate the change of corneal thickness before and after laser in situ keratomileusis and to calculate the acculate ablation depth on corneal during the operation to choose suitable patients. Methods 200 myopia patients were treated by LASIK. The change in corneal thickness were measured before and more than 6 months after the surgery. Results 200 myopia patients were treated by LASIK. The central thickness of the cornea and the refraction could be stable in six months after the operation. The ablation depth on cornea to remove each myopic diopter is about 13.20μm. Conclusion LASIK is safe and rehiable to treat ngopia, It is superiors to PRT.
