UNASSIGNED：通过将其与Barrett复曲面计算器（BTC）和Kane复曲面计算器（KTC）结合模拟角膜曲率测量值（SimK）进行比较，来评估使用制造商在线计算器的总角膜屈光力（TCRP）测量值的方法。
UNASSIGNED：这是一个回顾性病例系列。对患者记录进行了审查，以确定在复曲面IOL植入前使用IOLMaster700和Pentacam记录的生物测量的患者以及植入后的屈光随访数据。根据所使用的计算方法和测量值，通过矢量分析计算残余散光的预测误差。
未经授权：共纳入56例患者的70只眼。ATCTCRP的平均绝对散光预测误差为0.6±0.32、0.59±0.35和0.61±0.35D,BTCSimK,和KTCSimK计算器,分别为(P=0.934)，预测误差的质心为0.3D@178°，0.11D@102°,和0.09D@147°，分别为(P=0.23)。在有规则的子组中，ATCTCRP的预测误差质心为0.34D@176°，在三种计算方法中最高(P=0.046)。
未经批准：ATCTCRP，BTCSimK,和KTCSimK计算器在散光预测精度方面具有相似的性能。ATCTCRP计算器与TCRP的4.0-mm顶点/环读数相结合，略微旨在导致违规残留散光。
To evaluate a method using measured values of total corneal refractive power (TCRP) for a manufacturer\'s online calculator by comparing it with the Barrett toric calculator (BTC) and
Kane toric calculator (KTC) combined with simulated keratometry values (SimK).
This was a retrospective case series. Patient records were reviewed to identify the patients who had biometry with the IOL Master 700 and Pentacam recorded before toric IOL implantation and refractive follow-up data after implantation. The predicted error in residual astigmatism was calculated by vector analysis according to the calculation methods and the measurements used.
A total of 70 eyes of 56 patients were included. The mean absolute astigmatism prediction errors were 0.6 ± 0.32, 0.59 ± 0.35, and 0.61 ± 0.35 D for the ATCTCRP, BTCSimK, and KTCSimK calculators, respectively (P = 0.934), and the centroid of the prediction errors were 0.3 D @ 178°, 0.11 D @ 102°, and 0.09 D @ 147°, respectively (P = 0.23). In the with-the-rule subgroup, the centroid of the prediction error was 0.34 D @ 176° for ATCTCRP and was the highest among the three calculation methods (P = 0.046).
The ATCTCRP, BTCSimK, and KTCSimK calculators had similar performance with regards to their astigmatism prediction accuracy. The ATCTCRP calculator combined with 4.0-mm apex/ring readings of TCRP was slightly intended to result in against-the-rule residual astigmatism.
