Abstract

Study design: Prospective case series.

Prcis: This prospective study determines which formulas can best predict the refractive outcome in patients with primary angle closure disease (PACD) after cataract surgery.

Objective: To compare the accuracy of 6 intraocular lens power calculation formulas, Barrett Universal II (BU II), Haigis, Hoffer Q, Holladay I, Kane and SRK/T, in eyes with PACD.

Patients and methods: Patients diagnosed with PACD and cataracts and who met the indication for cataract surgery were enrolled in the study. Six intraocular lens power calculation formulas were used to calculate the refractive diopter. The percentage of eyes with prediction error (PE) within ±0.50 D and the median absolute PE were compared to determine the accuracy of different formulas in patients with PACD. Subgroup analysis was performed according to axial length (AL). The accuracy of BU II was compared between patients with PACD and patients with age-related cataracts.

Results: One hundred five patients (105 eyes) with PACD and 35 patients (35 eyes) with age-related cataracts were enrolled in the study. Haigis, Kane, and BU II formula achieved a comparable outcome and outperformed over the other 3 formulas in patients with PACD. Subgroup analysis showed that the group with long AL has lower values of median absolute PE. PE was significantly positively correlated with AL and negatively correlated with relative lens position when calculated using BU II and Kane.

Conclusions: Haigis, Kane, and BU II formula achieved a comparable outcome and outperformed over the other 3 formulas in patients with PACD.

原发性角膜闭合患者不同眼内透镜功率计算公式的比较。
目的:比较Barrett Universal Ⅱ(BU Ⅱ)、Haigis、Hoffer QST、HolladayⅠ、Kane和SRK/T六种眼内晶状体功率计算公式在原发性角膜闭合症(PACD)患者中的准确性:设计:前瞻性病例系列:设计:前瞻性病例系列:方法:将确诊为 PACD 和白内障且符合白内障手术指征的患者纳入研究。采用六种眼内晶体力量计算公式计算屈光度数。比较了预测误差(PE)在±0.50D以内的眼的百分比和绝对预测误差(MedAE)的中位数,以确定不同公式在PACD患者中的准确性。根据轴长(AL)进行了分组分析。比较了PACD患者和年龄相关性白内障患者的巴雷特通用Ⅱ的准确性:结果:105 名 PACD 患者(105 只眼)和 35 名老年性白内障患者(35 只眼)参加了研究。海吉斯、凯恩和巴雷特通用Ⅱ号配方对 PACD 患者的疗效相当,且优于其他三种配方。亚组分析表明,长 AL 组的 MedAE 值较低。使用巴氏通用Ⅱ和凯恩计算时,PE与AL呈明显的正相关,而与相对晶状体位置(RLP)呈负相关:结论:在PACD患者中,Haigis、Kane和Barrett Universal Ⅱ配方的结果相当,且优于其他三种配方。
