Abstract
- To compare the performance of new-generation and traditional intraocular lens (IOL) calculation formulas in eyes undergoing combined silicone oil (SO) removal and cataract surgery and to evaluate the prediction accuracy of Wang-Koch (WK) adjustment in SO-filled long eyes.Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou, China.Retrospective consecutive case-series study.New-generation formulas (Barrett Universal II, Emmetropia Verifying Optical, Kane, and Ladas Super formulas) and traditional formulas (Haigis, Hoffer Q, Holladay 1, and SRK/T formulas) were compared. The performance of WK adjustment was assessed in eyes with axial length more than 26 mm. The median absolute error (MedAE) was the main parameter to evaluate the accuracy of formulas.A total of 211 participants (211 eyes) who underwent combined SO removal and phacoemulsification with IOL implantation were included. Four new-generation formulas displayed statistically significant lower MedAE (0.32 to 0.35 diopter [D]) and higher percentage of eyes within ±1.00 D of prediction error (85.31% to 87.20%) compared with those of the traditional formulas (MedAE: 0.39 to 0.50 D; ±1.00 D: 81.04% to 81.99%, P.05). For SO-filled long eyes, all traditional formulas showed hyperopic bias (0.36 to 0.65 D, P.05), except for Haigis formula (0.28 D, P = .083), and this bias could be corrected by WK adjustment (P.05). EVO formula displayed the lowest MedAE both in total (0.32 D) and in long eyes (0.33 D).New-generation formulas and traditional formulas with WK adjustment showed satisfactory prediction accuracy in eyes undergoing combined SO removal and cataract surgery. EVO formula displayed the highest accuracy.
