目的：比较年龄相关性白内障患者术前Lenstar LS900和KR-1全自动验光仪测量角膜曲率及角膜散光各参数的差异。方法收集我院年龄相关性白内障患者76例（76眼），术前分别通过Lenstar LS900和KR-1全自动验光仪测量角膜相关参数，包括平坦角膜曲率（K1）、陡峭角膜曲率（K2）、K1和K2的平均值（Km）、散光值以及散光轴位，其中将角膜散光通过傅立叶矢量转换公式转换成矢量表示法（J0，J45）进行比较。结果 Lenstar LS900测量K1、K2、Km、J0和J45分别为（43.960±1.440）D、（44.901±1.319）D、（44.430±1.336）D、0.043±0.402、0.017±0.425；KR-1全自动验光仪测量K1、K2、Km、J0和J45分别为（44.007±1.400）D、（44.859±1.338）D、（44.433±1.330）D、-0.058±0.322、0.031±0.419；差异均无统计学意义（均P＞0.05）。Bland-Altman分析说明两种仪器的检测结果具有95%的一致性界限。结论 Lenstar LS900及KR-1全自动验光仪均可以应用于年龄相关性白内障患者术前测量角膜散光的各项参数。

Objective To compare the differences of corneal keratometry and corneal astigmatism measured by Len?star LS900 and KR-1 auto-refractor of age-related cataract. Methods Seventy-six patients with cataract (76 eyes) were in?cluded in this study. Flat keratometry (K1), steep keratometry (K2), mean keratometry (Km) and astigmatism were measured before operation by Lenstar LS900 and KR-1 auto-refractor. The parameters of astigmatism were transformed into J0 and J45 by Fourier vector transform, and which was compared. Results Values of K1, K2, Km, J0 and J45 were (43.960±1.440) D, (44.901±1.319)D, (44.430±1.336)D, 0.043±0.402 and 0.017±0.425 measured by Lenstar LS900, respectively, and which measured by KR-1 auto-refractor were (44.007 ± 1.400)D, (44.859 ± 1.338)D, (44.433 ± 1.330)D,-0.058 ± 0.322 and 0.031 ± 0.419, respectively. There was no statistical difference between these values measured by two instruments ( P>0.05). The Bland-Altman plots showed that two devices had coincident results for corneal parameters. Conclusion Lenstar LS900 and KR-1 auto-refractor can be applied in the measurement of corneal astigmatism of age-related cataract before surgery.
