■为了比较现代人工晶状体(IOL)屈光力计算公式与较旧公式的精度,如SRK/T和HofferQ,在小儿白内障手术中。
■这项回顾性研究包括100名接受常规白内障手术并在囊袋内植入原发性IOL的儿童的100只眼。本研究使用了四种IOLMaster700综合配方:SRK/T,HofferQ,海吉斯,和巴雷特环球II(BUII)。此外,使用了以下公式:EVO2.0、HillRBF3.0、HofferQST、凯恩,和珍珠DGS,可以在线获得。
■SRK/T与大多数其他公式之间存在统计学上的显着差异,除了HofferQ,HofferQST,和BUII(p<0.05)。SRK/T产生的最低中位数绝对误差(MedAE)为0.63D。其次是BUII(0.66D),HofferQ,和HofferQST(0.68D)。SRK/T在±0.50D内的病例百分比也最高(占病例的43%)。对于2至5岁的患者,在MedAE=0.44D的情况下,SRK/T公式产生的统计学结果明显优于所有其他包含的公式(p<0.05),58.33%和87.50%的病例在预期屈光的±0.50D和±1.0D内,分别。
■SRK/T公式显示了小儿白内障手术中最佳的IOL功率计算结果,其次是BUII,HofferQ,和HofferQST。在2-5岁的儿童中,SRK/T公式优于所有其他公式,其次是BUII和HofferQST公式。在5岁以上的儿童中,不同配方之间没有统计学上的显着差异(p>0.05);在该年龄组(5-10岁)中,HofferQ和SRK/T显示MedAE稍好。
UNASSIGNED: To compare the accuracy of modern intraocular lens (IOL) power calculation formulas with that of older formulas, such as SRK/T and Hoffer Q, in pediatric cataract surgery.
UNASSIGNED: This retrospective study included 100 eyes of 100 children who underwent routine cataract surgery with primary IOL implantation in a bag. This study used four IOLMaster 700 integrated formulas: SRK/T, Hoffer Q, Haigis, and Barrett Universal II (BUII). In addition, the following formulas were used: EVO 2.0, Hill RBF 3.0, Hoffer QST,
Kane, and PEARL DGS, which are available online.
UNASSIGNED: There was a statistically significant difference between SRK/T and most other formulas, except for Hoffer Q, Hoffer QST, and BUII (p < 0.05). SRK/T yielded the lowest median absolute error (MedAE) of 0.63 D. This was followed by the BUII (0.66 D), Hoffer Q, and Hoffer QST (0.68 D). SRK/T also yielded the highest percentage of cases within ± 0.50 D (43% of the cases). For patients aged 2 to 5 years, SRK/T formula yielded statistically significantly better results than all other included formulas (p < 0.05) with MedAE = 0.44 D, 58.33% and 87.50% of the cases were within ± 0.50 D and ± 1.0 D of intended refraction, respectively.
UNASSIGNED: The SRK/T formula showed the best IOL power calculation results in pediatric cataract surgery, followed by BUII, Hoffer Q, and Hoffer QST. In children aged 2-5 years, the SRK/T formula outperformed all other formulas, followed by the BUII and Hoffer QST formulas. In children older than 5 years, there was no statistically significant difference between the different formulas (p > 0.05); Hoffer Q and SRK/T showed slightly better MedAE in this age group (5-10 years).
