To compare the total corneal astigmatism (TCA) measured by IOLMaster 700 and Pentacam and to investigate the consistency of corneal keratometry (CK) measured by IOLMaster and Pentacam.
Cataract patients were retrospectively enrolled in March and April, 2021. Retrospective analysis was performed on those patients with binocular and monocular CK measured by IOLMaster and Pentacam.
A total of 102 patients (204 eyes) were included, 64 of whom were female (62.75%). The flat (K1) and steep (K2) CK of anterior corneal surface (ACS) and flat (TK1) and steep (TK2) of total cornea measured with IOLMaster 700 were 44.16 ± 1.60 D, 45.09 ± 1.68 D, 44.12 ± 1.62 D, and 45.14 ± 1.69 D, respectively. Those measured with Pentacam were 44.31 ± 1.57 D, 45.22 ± 1.65 D, 44.15 ± 1.67 D, and 45.19 ± 1.82 D, respectively. The astigmatism of ACS and TCA were -0.94 ± 0.63 D and -1.02 ± 0.69 D ( < 0.01) in the IOLMaster group and -0.90 ± 0.59 D and -1.05 ± 0.81 D in the Pentacam group, respectively ( < 0.01). TCA measurement results of IOLMaster and Pentacam were consistent (Pearson = 0.710, < 0.01), and there was no significant difference ( = 0.591).
Total corneal astigmatism measured by IOLMaster was consistent with that measured by Pentacam. The difference between the astigmatism of anterior corneal surface and total cornea was detected in the measurement of IOLMaster and Pentacam, respectively.
比较 IOLMaster 700 和 Pentacam 测量的总角膜散光（TCA），并研究 IOLMaster 和 Pentacam 测量的角膜曲率（CK）的一致性。
2021 年 3 月和 4 月回顾性纳入白内障患者。对双眼和单眼 IOLMaster 和 Pentacam 测量的 CK 进行回顾性分析。
共纳入 102 例（204 只眼）患者，其中 64 例（62.75%）为女性。IOLMaster 700 测量的前角膜表面（ACS）平 K1 和陡 K2 以及总角膜平 TK1 和陡 TK2 分别为 44.16 ± 1.60 D、45.09 ± 1.68 D、44.12 ± 1.62 D 和 45.14 ± 1.69 D。Pentacam 测量的分别为 44.31 ± 1.57 D、45.22 ± 1.65 D、44.15 ± 1.67 D 和 45.19 ± 1.82 D。IOLMaster 组 ACS 和 TCA 的散光分别为-0.94 ± 0.63 D 和-1.02 ± 0.69 D（ < 0.01），Pentacam 组分别为-0.90 ± 0.59 D 和-1.05 ± 0.81 D（ < 0.01）。IOLMaster 和 Pentacam 的 TCA 测量结果一致（Pearson = 0.710， < 0.01），差异无统计学意义（ = 0.591）。
IOLMaster 测量的总角膜散光与 Pentacam 测量的结果一致。IOLMaster 和 Pentacam 分别检测到前角膜表面和总角膜散光的差异。
