摘　　要：目的：评价放射状角膜切开术（ＲＫ）中微穿孔对术后１年内角膜内皮的影响。方法：应用角膜内皮镜及角膜内皮分析仪研究４８例ＲＫ术中微穿孔和未穿孔眼的角膜内皮形态学变化，分别在术前及术后１、３、６、１２个月行角膜内皮检查及分析。结果：比较手术前后角膜内皮的数量、平均面积、最大面积和最小面积，穿孔眼及未穿孔眼差异无显著性，但内皮细胞面积两组都有扩大的趋势。结论：ＲＫ术后一年内无论微穿孔还是未穿孔眼的角膜内皮数量及形态学变化均无显著性改变。但角膜内皮面积在两组均有扩大的趋势，角膜微穿孔不是主要影响因素。To evaluate the influence of corneal microperforation on the corneal endothelium within one year following radial keratotomy (RK).We studied the morphologic characteristics of the corneal endothelium of 48 patients undergoing RK with or without corneal perforation.They were examined by specular microscope and corneal endothelial analyser preoperatively,and 1,3,6,12 months postoperatively thereafter.Compared the number,ave rage area,maximum area and minimum area or endothelium pre and postoperatively,the difference from the eye with or without microperforation is not significant,but endothelial area in both group has a tendency of enlargement.The number and morphologic characteristics of endothelium in RK with or without microperforation one year after operation do not change significantly,but the endothelial area has the tendency of enlargement,which is not mainly influenced by microperforation.
