〔Abstract〕 Objective To compare the difference and consistency of corneal curvature and astigmatism measured by Lenstar ls900, VERION, OPD-Ⅲ and Pentacam. Methods A total of 94 patients (128 eyes) with age-related cataract diagnosed and treated in the Affiliated Eye Center of Xiamen University from March 2019 to June 2019 were selected. Lenstar ls900, VERION, OPD-Ⅲ and Pentacam devices were used to measure and analyze the corneal curvature, astigmatism and axial direction (vector expression J0 and J45) in 128 eyes. Paired t-test was used to compare the results of different devices. Bland-Altman curve method was used to evaluate the consistency. Results There was no significant difference between Lenstar ls900 and VERION, OPD-Ⅲ and Pentacam in flat axial curvature (K1), steep axial curvature (K2), average curvature (Km), astigmatism, J0 and J45.The Lenstar ls900 and other devices Km and 95 % conformance limit (95 %LoA) and the range were all > 1 D. Conclusion There was no significant difference between Lenstar ls900 and VERION, OPD-Ⅲ, Pentacam SimK and Pentacam TCRP in the measurement of corneal curvature and astigmma. When using Lenstar, the latter three data can be used as reference, and the replacement should be cautious.
