摘要
目的：评价有无术前无晶状体前房深度（aph-ACD）的儿童无晶状体人工晶状体（IOL）度数计算公式的准确性。方法：将102例小儿二期人工晶状体植入术患者（150眼）分为囊内组和睫状沟组。计算了9种IOL度数计算公式的预测误差，包括：1)不需要ACD的公式：Hoffer Q、Holladay 1、SRK/T；2)无需或可输入ACD: Barrett Universal II (BUII), Emmetropia verification Optical (EVO) 2.0, Ladas Artificial Intelligence Super (Ladas AI)；3)需要ACD: Haigis， Kane和Pearl-DGS。计算平均预测误差（ME）、平均绝对误差（MAE）、中位数绝对误差（MedAE）以及在±0.25、±0.50、±0.75和±1.00 D范围内的眼百分率。结果：对于BUII， EVO 2.0和Ladas AI，与未使用aph-ACD相比，aph-ACD的MedAE更高(BUII: 1.27 vs 1.13 D, EVO 2.0: 1.26 vs 1.06 D, Ladas AI: 1.30 vs 1.10 D；结论：无论是袋式人工晶状体植入术还是沟状人工晶状体二次植入术，均不能提高儿童无晶状体人工晶状体计算的准确性。aph-ACD与儿童无晶状体有效晶状体位置的关系值得进一步研究。
Accuracy of IOL power calculation in pediatric aphakia secondary implantation.
Aim: To evaluate the accuracy of intraocular lens (IOL) power calculation formulas with/without preoperative aphakic anterior chamber depth (aph-ACD) in pediatric aphakia.
Methods: A total of 102 pediatric patients (150 eyes) undergoing secondary IOL implantation were divided into two groups (in-the-bag or ciliary sulcus). Prediction error was calculated for 9 IOL power calculation formulas, including: 1) not requiring ACD: Hoffer Q, Holladay 1, SRK/T; 2) usable without or with entering ACD: Barrett Universal II (BUII), Emmetropia Verifying Optical (EVO) 2.0, and Ladas Artificial Intelligence Super (Ladas AI); 3) requiring ACD: Haigis, Kane, and Pearl-DGS. Mean prediction error (ME), mean absolute error (MAE), median absolute error (MedAE) and the percentage of eyes within ±0.25, ±0.50, ±0.75, and ±1.00 D were calculated.
Results: For the BUII, EVO 2.0, and Ladas AI, with aph-ACD demonstrated a higher MedAE compared to without aph-ACD (BUII: 1.27 vs 1.13 D, EVO 2.0: 1.26 vs 1.06 D, Ladas AI: 1.30 vs 1.10 D; all P<0.05). Formulas requiring ACD (Haigis, Kane, and Pearl-DGS) exhibited larger MedAE than those not requiring aph-ACD (Hoffer Q, Holladay 1, and SRK/T; P<0.05). In the capsular group, the percentage of eyes within ±1.00 D ranged from 44.83% to 74.14%, and it was 19.57% to 32.61% in the sulcus group.
Conclusion: The introduction of aph-ACD does not improve the accuracy of IOL calculation for pediatric aphakia, regardless of in-the-bag or sulcus IOL secondary implantation. The relationship between aph-ACD and effective lens position in pediatric aphakia warrants further study.
