	abstract = {PurposeThe purpose of this study was to establish benchmarks for outcome indicators that may help ascertain the quality of pediatric cataract surgery with primary intraocular lens (IOL) implantation.Patients and methodsA retrospective chart review of patients older than 2 years undergoing cataract surgery with primary IOL implantation, by multiple surgeons in a tertiary-care center, from November 2005 to February 2016 was conducted. Patients with ocular comorbidities that would affect the outcomes were excluded. The outcome measures chosen were as follows: (1) final best corrected Snellen visual acuity (BCVA) in patients who had bilateral cataract surgery analyzed at the last clinic visit; (2) prediction error (PE)=expected refraction-actual refraction. Mean PE and mean absolute PE were assessed 1 month postoperatively, irrespective of age or laterality.ResultsMean age at surgery was 8.3{\textpm}4.6 years and mean follow-up duration was 3.7{\textpm}2.7 years. The results of outcome measures were as follows: (1) BCVA was 20/40 or better in 96\% (n=124 eyes, mean patient age: 8.3{\textpm}4.6 years). Remaining five eyes had amblyopia with two eyes having BCVA worse than 20/100 that did not respond to amblyopia treatment. (2) Mean PE was 0.3{\textpm}1.1 D and mean absolute PE was 0.9{\textpm}0.7 D. PE was within {\textpm}0.5 D in 43.0\%, {\textpm}1.0 D in 66\%, and {\textpm}2.0 D in 95\% (n=235 eyes).ConclusionGood visual acuity after cataract surgery should be expected for children with bilateral cataracts, setting a high benchmark similar to that recommended in adult cataract surgery. Prediction error is greater in pediatric eyes than in adult eyes, setting a lower benchmark. This study establishes benchmark for outcome indicators in pediatric patients older than 2 years undergoing cataract surgery with primary IOL implantation.},
