Evaluation of Higher-Order Aberrations in Children According to the Age

Abstract

Purpose: : To investigated the influence of age and refractive error on higher-order aberrations in children

Methods: : Observational cross-sectional studypatients: one hundred trenty two eyes of 70 children old from 5 to 15 years. Manisfest spherical equivalent was included enters -12.33 and +9.65 diopters.Aberrometry was performed with the same wavefront analyser.

Results: : Mean root mean square values of total aberrations according to the age were 0.30+/- 0.13 µm from 3 to 5 years, 0.29 +/- 0.11µm from 6 to 9 years and 0.36 µm +/- 0.16µm from 10 to 15 years. Sames results were found for third and fourth aberrations. Mean root mean square values of total aberrations according to the refractive error were 0.31 +/- 0.13 µm for children with no refractive error, 0.34 +/- 0.15 µm for average hyperopes, 0.27 +/-0.11 µm for average myopes, 0.28 +/-0.10 µm for strong hyperopes and 0.42 +/- 0.23 for strong myopes.

Conclusions: : Higher-order aberrations seems to increase with age. Higher-order aberrations were influenced by refractive error because strong myopes had greater levels compared other groups.We do not have to note difference betwenn medium and high pupillary size but we obtained values lower of totally, fourth and five order aberrations when the pupillary size was lower than 6.6 mm.
