摘　　要：目的对比OrbscanⅡ和Pentacam眼前节分析仪测量近视患者角膜地形图的差异。方法分别使用OrbscanⅡ和Pentacam眼前节分析仪测量119例近视患者角膜地形图,并对测量结果进行方差分析、配对t检验和Pearson相关分析。结果 OrbscanⅡ和Pentacam测得CCT平均值分别为(515.67±36.06)μm、(539.67±31.41)μm,差异有统计学意义(P<0.05);OrbscanⅡ测得角膜前后表面曲率、前后表面高度和瞳孔直径均显著高于Penta-cam;两种仪器测得角膜散光和前房深度无差异。结论两种仪器测得角膜地形图存在一定差异,在临床工作中不能将二者测量结果简单替代。Objective To compare the differences in measurements of corneal topography using Orbscan II and Pentacam antemior segment analysis systenn. Methods Corneal topography of 119 patients were obtained with Orbscan II and Pentacam , analysis of variance, paired t-test and Pearson correlation analysis were used to analyze the diffeerrence and correlation between these measurements. Results The mean CCT measured by Orbscan II and Pentacam were （515.67 ± 36.06 ） um and （ 539.67 ± 31.41 ）um respectively, there were statistical differences （ P 〈 0.05 ） ; the anterior and posterior corneal curvature, the anterior and pesterior corneal elevation and the corneal diameter obtained by Orbscan II were higher significantly than those by Pentaeam; there were no statlstleal diffexenees between Sim K and anterior chamber depth obtained by Orbscan II and Pentacam. Condustoa The eomead topographies measured by Orbscan II and Pentaeam have differenees, so the two measurements should not be used interehangeably in clinic.
