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 \u00b10.25, \u00b10.50, \u00b10.75, and \u00b11.00 D were calculated.\nRESULTS: 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&amp;#x003C;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&amp;#x003C;0.05). In the capsular group, the percentage of eyes within \u00b11.00 D ranged from 44.83% to 74.14%, and it was 19.57% to 32.61% in the sulcus group.\nCONCLUSION: 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.<\/jats:p>","DOI":"10.18240\/ijo.2025.07.12","type":"journal-article","created":{"date-parts":[[2025,6,20]],"date-time":"2025-06-20T07:17:27Z","timestamp":1750403847000},"page":"1294-1301","source":"Crossref","is-referenced-by-count":2,"title":["Accuracy
