摘要

Abstract

Objective

To investigate the change rules of lens by analyzing the relationship between lens morphology and axial length in adolescents.

Methods

A total of 285 adolescents (6~18 years old

570 eyes) who visited our ophthalmological department from May to June 2020 were enrolled in this study. Diopter

axial length

keratometry and lens parameters were obtained by optometry after cycloplegia

optical biomimetry (IOL Master) and anterior segment optical coherence tomography (CASIA2)

respectively. The subjects were divided into 3 age groups (6~10

11~14 and 15~8 years)

and were also assigned into 3 groups in accordance with their equivalent spherical specularity: hyperopia

emmetropia and myopia groups. One-way analysis of variance was adopted to compare lens parameters among different age and refractive groups

and their relationships with axial length were analyzed with Pearson correlation analysis and linear regression analysis.

Results

In different age groups

statistical differences were observed in the radius of anterior surface curvature and the diopter of lens (

0.05); And similar results were seen in above 2 parameters and in the thickness and diameter of lens among different refractive groups (

0.05). The curvature radius of the anterior and posterior surface

diopter

and thickness and diameter of lens were all significantly correlated with the ax

ial length of eye in different age groups and refractive groups (

0.001). In the hyperopia

emmetropia and myopia groups

with the increase of every 1 mm in ocular axis

the radius of anterior surface curvature was increased by 1.19

1.04 and 0.58 mm; the radius of posterior surface curvature was increased by 0.41

0.38 and 0.30 mm

the diopter was decreased by 1.68 D

1.44 D and 0.98 D; the thickness was reduced by 0.076

0.091 and 0.059 mm

and the diameter increased by 0.3

0.23 and 0.24 mm

respectively.

Conclusion

The disparity of lens parameters among different ages and refractive states in adolescents is mainly caused by the diversity of axial length. The morphological changes of the lens are coordinated with the growth of axial length

but the changes will be decreased with the growth.
