This study used four IOLMaster 700 integrated formulas: SRK/T, Hoffer Q, Haigis, and Barrett Universal II (BUII). In addition, the following formulas were used: EVO 2.0, Hill RBF 3.0, Hoffer QST, Kane, and PEARL DGS, which are available online.Results: There was a statistically significant difference between SRK/T and most other formulas, except for Hoffer Q, Hoffer QST, and BUII (p 0.05); Hoffer Q and SRK/T showed slightly better MedAE in this age group (5– 10 years).Keywords: pediatric biometry, IOL calculation, haigis, Barrett universal II, SRK/T, EVO 2.0, hill RBF 3.0, Kane, Hoffer QST
