Abstract

Purpose: To assess the accuracy of the Kane formula for intraocular lens (IOL) power calculation in the pediatric population.

Methods: The charts of pediatric patients who underwent cataract surgery with in-the-bag IOL implantation with one of two IOL models (SA60AT or MA60AC) between 2012 and 2018 in The Hospital for Sick Children, Toronto, Ontario, CanFada, were retrospectively reviewed. The accuracy of IOL power calculation with the Kane formula was evaluated in comparison with the Barrett Universal II (BUII), Haigis, Hoffer Q, Holladay 1, and Sanders-Retzlaff-Kraff Theoretical (SRK/T) formulas.

Results: Sixty-two eyes of 62 patients aged 6.2 (IQR 3.2-9.2) years were included. The SD values of the prediction error obtained by Kane (1.38) were comparable with those by BUII (1.34), Hoffer Q (1.37), SRK/T (1.40), Holaday 1 (1.41), and Haigis (1.50), all p > 0.05. A significant difference was observed between the Hoffer Q and Haigis formulas (p = 0.039). No differences in the median and mean absolute errors were found between the Kane formula (0.54 D and 0.91 ± 1.04 D) and BUII (0.50 D and 0.88 ± 1.00 D), Hoffer Q (0.48 D and 0.88 ± 1.05 D), SRK/T (0.72 D and 0.97 ± 1.00 D), Holladay 1 (0.63 D and 0.94 ± 1.05 D), and Haigis (0.57 D and 0.98 ± 1.13 D), p = 0.099.

Conclusion: This is the first study to investigate the Kane formula in pediatric cataract surgery. Our results place the Kane among the noteworthy IOL power calculation formulas in this age group, offering an additional means for improving IOL calculation in pediatric cataract surgery. The heteroscedastic statistical method was first implemented to evaluate formulas' predictability in children.

用凯恩公式评估儿童白内障手术人工晶状体度数。

目的:评估儿童人工晶状体(IOL)度数计算凯恩公式的准确性。方法:回顾性分析2012年至2018年加拿大安大略省多伦多病童医院接受白内障手术并采用两种人工晶状体(SA60AT或MA60AC)中的一种进行袋式人工晶状体植入术的儿童患者的病历。将Kane公式与Barrett Universal II (BUII)、Haigis、Hoffer Q、Holladay 1和Sanders-Retzlaff-Kraff Theoretical (SRK/T)公式进行比较，评估IOL度数计算的准确性。结果:纳入62例患者62只眼，年龄6.2 (IQR 3.2 ~ 9.2)岁。Kane预测误差的SD值(1.38)与BUII预测误差的SD值(1.34)、Hoffer Q预测误差的SD值(1.37)、SRK/T预测误差的SD值(1.40)、Holaday 1预测误差的SD值(1.41)、Haigis预测误差的SD值(1.50)相当，均p > 0.05。Hoffer Q和Haigis公式之间存在显著差异(p = 0.039)。Kane公式(0.54 D和0.91±1.04 D)与BUII (0.50 D和0.88±1.00 D)、Hoffer Q (0.48 D和0.88±1.05 D)、SRK/T (0.72 D和0.97±1.00 D)、Holladay 1 (0.63 D和0.94±1.05 D)、Haigis (0.57 D和0.98±1.13 D)的绝对误差中位数和平均误差均无差异，p = 0.099。结论:本研究首次探讨了凯恩公式在儿童白内障手术中的应用。我们的研究结果使Kane成为该年龄组值得注意的人工晶状体度数计算公式之一，为改善儿童白内障手术中的人工晶状体计算提供了额外的手段。异方差统计方法首次应用于评价公式在儿童中的可预测性。
