摘　　要：目的　探讨再次准分子激光原位角膜磨镶术 (LASIK)矫治屈光回退和欠矫的疗效。方法　收集 2 0 0 0年 12月～2 0 0 2年 8月因屈光回退和欠矫在我院行再次LASIK者 3 8例 ( 70眼 ) ,随访 1年 ,观察术中术后并发症 ,术眼的屈光度。探讨再次LASIK的安全性、疗效及手术时机。结果　 3 8例 ( 70眼 )术中术后无不良并发症发生 ,术后 1年裸眼视力达术前最佳矫正视力者 68眼 ( 97 14 %) ,残余屈光度在± 1 0 0D以内者 69眼 ( 98 5 7%) ,术后 3月和 6月屈光度分别为 ( -0 3 5± 1 12 )D和( -0 5 2± 1 0 1)D ,术后 1年无角膜膨隆或圆锥角膜发生。结论　在保留角膜基质床的厚度≥ 2 5 0 μm的前提下行再次LASIK 。Objective To evaluate the clinical effects of novo laser in situ keratomileusis on refraction return or insufficient correct. Methods 38 cases (70 eyes) had accepted novo laser in situ keratomileusis for their refraction return or insufficient correct, and had been followed up for 12 months. Results All the cases had no operative or postoperative complication occurred. After 12 months follow up, the naked vision of 68 eyes (97.14%) got equal to or better than preoperative corrected vision. The rest diopter was less than +1D in 69 eyes (98.57%) Conclusion When the corneal stroma thickness is > 250 μm, novo laser in situ keratomileusis is a safe and effective method for refraction return or insufficient correct.
