Comparison of anterior segment parameters and axial lengths of myopic, emmetropic, and hyperopic children

Purpose To compare the anterior segment parameters of myopic, hyperopic, and emmetropic children by using optical biometry. Methods This prospective cross-sectional study included 150 eyes of 150 children between 6 and 16 years old. The eyes were divided into three groups according to their spherical equivalent (SE) refractive error values as myopic [between − 1.0 and − 6.0 diopter (D)], emmetropic (between + 0.50 and − 0.50 D), and hyperopic (between + 1. 0 and + 3.0 D). Axial length (AL), central corneal thickness, anterior chamber depth (ACD), lens thickness (LT), and mean keratometry ( K mean) measurements were obtained by an optical biometry (LenStar LS 900, Haag Streit Diagnostics) were compared between the groups. Results There were no statistically significant differences regarding the ages and genders of the participants between the groups ( p > 0.05). The mean SE refractive error values were − 2.20 ± 0.71 D in myopic, − 0.08 ± 0.49 D in emmetropic, and + 2.06 ± 0.53 D in hyperopic eyes. The mean AL values were 24.50 ± 0.69, 23.41 ± 0.61, and 22.33 ± 0.61 mm, respectively, in myopic, emmetropic, and hyperopic eyes ( p
