Abstract

Aim: To investigate the influence of postoperative intraocular lens (IOL) positions on the accuracy of cataract surgery and examine the predictive factors of postoperative biometry prediction errors using the Barrett Universal II (BUII) IOL formula for calculation.

Methods: The prospective study included patients who had undergone cataract surgery performed by a single surgeon from June 2020 to April 2022. The collected data included the best-corrected visual acuity (BCVA), corneal curvature, preoperative and postoperative central anterior chamber depths (ACD), axial length (AXL), IOL power, and refractive error. BUII formula was used to calculate the IOL power. The mean absolute error (MAE) was calculated, and all the participants were divided into two groups accordingly. Independent t-tests were applied to compare the variables between groups. Logistic regression analysis was used to analyze the influence of age, AXL, corneal curvature, and preoperative and postoperative ACD on MAE.

Results: A total of 261 patients were enrolled. The 243 (93.1%) and 18 (6.9%) had postoperative MAE<1 and >1 D, respectively. The number of females was higher in patients with MAE>1 D (χ ² = 3.833, P=0.039). The postoperative BCVA (logMAR) of patients with MAE >1 D was significantly worse (t=-2.448; P=0.025). After adjusting for gender in the logistic model, the risk of postoperative refractive errors was higher in patients with a shallow postoperative anterior chamber [odds ratio=0.346; 95% confidence interval (CI): 0.164, 0.730, P=0.005].

Conclusion: Risk factors for biometry prediction error after cataract surgery include the patient's sex and postoperative ACD. Patients with a shallow postoperative anterior chamber are prone to have refractive errors.

Barrett通用II型人工晶状体配方在中国患者生物计量预测误差的危险因素。

目的：探讨术后人工晶状体（IOL）位置对白内障手术准确性的影响，并探讨应用Barrett Universal II (BUII) IOL公式计算术后生物计量预测误差的预测因素。方法：前瞻性研究纳入了2020年6月至2022年4月期间接受单一外科医生白内障手术的患者。收集的数据包括最佳矫正视力（BCVA）、角膜曲率、术前和术后中央前房深度（ACD）、眼轴长度（AXL）、IOL度数和屈光不正。采用BUII公式计算人工晶状体度数。计算平均绝对误差（MAE），并将所有参与者相应地分为两组。采用独立t检验比较组间变量。采用Logistic回归分析年龄、AXL、角膜曲率、术前术后ACD对MAE的影响。结果：共纳入261例患者。243例（93.1%）和18例（6.9%）术后发生MAE1 D。MAE患者中女性患者较多（χ 2 = 3.833， P=0.039）。MAE患者的术后BCVA （logMAR）显著差(t=-2.448；P = 0.025)。在logistic模型中调整性别后，术后浅前房患者发生术后屈光不正的风险更高[优势比=0.346；95%置信区间（CI）： 0.164, 0.730， P=0.005]。结论：白内障术后生物计量预测误差的危险因素包括患者的性别和术后ACD。术后前房浅的患者容易发生屈光不正。
