摘　　要：目的评估角膜地形图引导的传导性角膜成形术(CK)治疗兔眼准分子激光上皮下角膜磨镶术(LASEK)术后的中、低度角膜散光的效果。方法正常新西兰大白兔15只(30眼)制作LASEK术后角膜散光模型。其中的中、低度散光22眼(中度散光组14眼,低度散光组8眼)在角膜地形图引导下行CK治疗。结果经CK治疗后,中、低度散光组的平均角膜散光度较术前明显减少(P<0.05);各组术后1周、1月、3月间散光度数无差异(P>0.05)。结论角膜地形图引导的CK对矫正LASEK术后的中、低度角膜散光是安全、有效的。Objective To evaluate early efficacy of conductive keratoplasty under corneal topography for the treatment of low to moderate astigmatism after LASEK. Methods The models of astigmatism after LASEK were set up in 15 normal New Zealand white rabbits. Then, the rabbit eyes of low to moderate astigmatism were picked out （ 14 moderate astigmatism eyes and 8 low astigmatism eyes） and treated with CK under corneal topography. Results The average astigmatism of low to moderate group after CK were reduced obviously compared with those preoperatively, and there were no significant differences at all postoperative intervals. Conclusion Conductive keratoplasty for low to moderate astigmatism after LASEK was safe and effective.
