摘　　要：目的探讨比较IOL Master700和Pentacam在白内障患者术前检测角膜曲率与散光的差异性、相关性及一致性。方法收集2023年6月至2023年10月白内障患者115例203眼。分别采用IOL Master与Pentacam测量患者的角膜前表面曲率及散光度数、后表面曲率及散光度数和全角膜曲率及散光度数,分析两种仪器的差异性、相关性和一致性。结果IOL Master700与Pentacam测量角膜后表面的Ks、Kf和Km的差异均具有统计学意义(P<0.05),其余结果差异均无统计学意义(P>0.05);两种仪器分别测量Ks、Kf、Km和△k的数据有较好的相关性,Ks、Kf、Km较△k相关性更高(P<0.001);Bland-Altman分析结果显示IOL Master与Pentacam测量患者的角膜前表面曲率的一致性较好,角膜后表面曲率及散光度数的一致性较差。结论IOL Master700与Pentacam在测量角膜前表面曲率方面差异性小,一致性好;在测量全角膜曲率方面差异性较小,一致性较好;在测量角膜后表面曲率方面存在差异,一致性较差;在测量角膜前后表面及全角膜散光度方面,差异性较小,但一致性较差。总体来说,两种仪器测量数据临床使用时不可相互替代,但可相互参考,需综合分析测量结果进行选择。Objective To investigate the difference and consistency of corneal keratometry and astigmatism measured by IOL Master700 and Pentacam in cataract patients.Methods A total of 115 cataract patients(203 eyes)were selected from June 2023 to October 2023.Corneal keratometry and astigmatism of the anterior corneal surface,posterior corneal surface and total cornea of cataract patients were measured by IOL Master700 and Pentacam,respectively.Differences,correlations and agreement between the two instruments were analysed.Results Significant differences were found in Ks,Kf and Km of the posterior corneal surface between IOL Master700 and Pentacam(P<0.05),while no significant differences were found in other parameters.Pearson correlation analysis showed a strong correlation between the two instruments in the measurement of Ks,Kf,Km and△k.The correlations for Ks,Kf and Km were more significant than those for△k(P<0.001).Bland-Altman analysis showed strong agreement between the anterior corneal surface Ks,Kf and Km measured by the two instruments,but poor agreement between the posterior corneal surface Ks,Kf and Km.Conclusion Firstly,the IOL Master700 and Pentacam show moderate differences and strong consistency in anterior corneal surface keratometry.Secondly,there are minimal differences and significant consistency in the measurement of total corneal keratometry.However,significant differences and poor consistency are observed in the posterior corneal surface keratometry.Although the differences in astigmatism measurements for the anterior corneal surface,posterior corneal surface and total cornea are minimal between two devices,the consistency is poor.Overall,measurement data from the IOL Master700 and Pentacam should not be used interchangeably in clinical practice,but can be cross-referenced.A comprehensive analysis of the measurement results is recommended for clinical decision making.
