Purpose:

To compare the accuracy of Barrett Universal II formula with other formulas (Holladay 2, Hoffer Q, and SRK/T formulas) in the prediction of postoperative refraction for pediatric intraocular lens implantation.

Setting:

Academic medical center/children’s hospital, San Francisco, California.

Design:

Retrospective case series.

Methods:

Children aged 16 years or younger who underwent cataract extraction and IOL implantation (2012 to 2019) and had refraction assessed at 3 to 16 weeks postoperatively were included. Prediction error (PE) was calculated as postoperative mean spherical equivalent minus the target refraction. Mean, median, and standard deviation was calculated for PE and absolute PE. Performance across covariables (axial length, age, biometry type, keratometry, etc.) was studied, and a multivariate regression analysis was performed using a single prediction model for each formula.

Results:
