PURPOSE
To compare the biometric measurements obtained from the Pentacam AXL Wave, IOLMaster 700, and ANTERION and calculate the recommended intraocular lens power using the Barrett Formulae.
METHODS
This was a retrospective cross-sectional study of patients who underwent biometry using the Pentacam AXL Wave, IOLMaster 700, and ANTERION. Flat keratometry (K1), steep keratometry (K2), anterior chamber depth (ACD), and axial length (AL) from each device were measured and compared. These parameters were used to calculate the recommended IOL powers using the Barrett formula.
RESULTS
The study included 252 eyes of 153 patients. The IOLMaster had the highest acquisition rate among the two biometers. The Pentacam obtained the shortest mean AL, the IOLMaster measured the highest mean keratometry values, and the ANTERION measured the highest mean ACD. In terms of pairwise comparisons, keratometry and axial length were not significantly different between the Pentacam-IOLMaster and ANTERION-IOLMaster groups, while the rest of the pairwise comparisons were statistically significant. In nontoric and toric eyes, 35-45% of patients recommended the same sphere of IOL power. In another 30-40%, the Pentacam and ANTERION recommended an IOL power one step greater than that of the IOLMaster-derived data. 50% of the study population recommended the same toric-cylinder IOL power.
CONCLUSIONS
The Pentacam AXL Wave, IOLMaster 700, and ANTERION can reliably provide data for IOL power calculations; however, these data are not interchangeable. In nontoric and toric eyes, 35-45% of cases recommended the same sphere IOL power, and in another 30-40%, the Pentacam and ANTERION recommended one-step higher IOL power than the IOLMaster-derived data. In targeting emmetropia, selecting the first plus IOL power is advisable when using the Pentacam and ANTERION to approximate the IOL power calculations recommended by the IOLMaster 700.
目的
比较 Pentacam AXL Wave、IOLMaster 700 和 ANTERION 获得的生物测量值，并使用 Barrett 公式计算推荐的人工晶状体（IOL）度数。
方法
这是一项回顾性的横断面研究，纳入了使用 Pentacam AXL Wave、IOLMaster 700 和 ANTERION 进行生物测量的患者。测量并比较了每台设备的平角膜曲率（K1）、陡角膜曲率（K2）、前房深度（ACD）和眼轴长度（AL）。使用 Barrett 公式根据这些参数计算推荐的 IOL 度数。
结果
该研究共纳入了 153 例患者的 252 只眼。在这两种生物测量仪中，IOLMaster 的获取率最高。Pentacam 获得的平均眼轴最短，IOLMaster 测量的平均角膜曲率值最高，而 ANTERION 测量的平均前房深度最高。在两两比较中，Pentacam-IOLMaster 组和 ANTERION-IOLMaster 组之间的角膜曲率和眼轴长度无显著差异，而其余两两比较则有统计学意义。在非散光和散光眼中，35%-45%的患者推荐相同的 IOL 球镜度数。在另外 30%-40%的患者中，Pentacam 和 ANTERION 推荐的 IOL 度数比 IOLMaster 数据高一个等级。在 50%的研究人群中，推荐了相同的散光-圆柱镜 IOL 度数。
结论
Pentacam AXL Wave、IOLMaster 700 和 ANTERION 可以可靠地提供 IOL 度数计算数据；然而，这些数据不可互换。在非散光和散光眼中，35%-45%的病例推荐相同的球镜 IOL 度数，在另外 30%-40%的病例中，Pentacam 和 ANTERION 推荐的 IOL 度数比 IOLMaster 数据高一个等级。在以正视为目标的情况下，使用 Pentacam 和 ANTERION 近似 IOLMaster 700 推荐的 IOL 度数计算时，选择首加 IOL 度数较为合适。
