Implication

Retrospective study finds varying axial length control between orthokeratology and highly aspherical lenslets in myopic children, indicating age- and severity-dependent treatment efficacy.

Key Points

To compare 12-month axial length elongation between orthokeratology contact lenses and highly aspherical lenslets spectacle lenses in children with myopia.
Retrospective propensity score-matched study evaluating 3,122 matched pairs (N = 6,244) of children with baseline spherical equivalent refraction between -0.50 and -9.00 D.
Assessed 12-month axial length (AL) elongation across age subgroups (8-9, 10-11, and 12-14 years) and myopia severity tiers (mild: -0.50 to -3.00 D; moderate: -3.00 to -5.00 D; high: -5.00 to -9.00 D).
Overall, the highly aspherical lenslets (HAL) group achieved significantly less 12-month AL elongation than the orthokeratology (OK) group (0.15 ± 0.17 mm vs. 0.20 ± 0.18 mm; P < 0.001).
HAL spectacles showed less AL elongation in children aged 8-9 years (0.19 ± 0.18 mm vs. 0.26 ± 0.18 mm; P < 0.001), 10-11 years (0.12 ± 0.17 mm vs. 0.17 ± 0.17 mm; P < 0.001), and mild myopia (P < 0.001), with no significant difference at ages 12-14 years (P = 0.305).
OK lenses achieved significantly less AL elongation than HAL spectacles in children with high myopia (P < 0.001), with no significant difference observed for moderate myopia (P = 0.950).
