摘　　要：目的:分析放射状角膜切开术(RK)穿孔对角膜内皮的影响,为临床屈光手术提供科学依据。方法:观察RK术后角膜内皮细胞的变化及视力、临床屈光、角膜曲率及眼轴长度的变化。结果:48例双眼RK术后穿孔组与未穿孔组配对比较,可知两组的视力、临床屈光、角膜曲率及眼轴长度均无明显差异,但内皮细胞面积均有增大趋势。结论:放射状角膜切开术后微穿孔和来穿孔对角膜内皮的影响基本相同。角膜内皮面积增加主要因术后角膜变形牵拉所致,与穿孔无关。Purpose:The effects of microperforation after radiative keratotomy(RK)on cornea! endothelium were observed in order to provide useful data for ametropia operation in clinics.Methods:The changes of cornea! endothelium,clinical diopter,corneal curvature,and length of eyeball axis were observed.Results:There were no difference between the microperforation and non-microperforadon groups in the vision,clinical diopter,corneal curvature and length of eye-ball axis.The corneal endothium area were increased in both groups.Conclusion:The effects of microperforation after RK on corneal endothelium were the same as non-microperfora-tion.The area changes of corneal endothelium was induced by the drawing of the cornea deforming,not related to the perforation.
