Myopia Control Efficacy of Spectacle Lenses with Dual-Index Aspherical Lenslets: A 1-Year Randomized Clinical Trial.

ABSTRACT:

Objective

To examine the myopia control efficacy, in terms of axial elongation, of a new myopia control spectacle lenses with Dual-Index Aspherical Lenslets (DIAL) embedded within the lens, compared with single-vision spectacle lenses (SVLs) over a 1-year period.

Design

A prospective, randomized, double-masked clinical trial.

Participants

Eighty children aged 8 to 13 years with myopia (spherical equivalent refraction [SER] between -0.75 and -4.75 diopters [D]) were recruited.

Intervention

Participants were randomized to either the DIAL or SVL spectacle lenses group (1:1 ratio).

Main outcome measures

Axial length (AL), noncycloplegic subjective refraction, and best-corrected visual acuity (BCVA) were measured at baseline and 6-month intervals. Questionnai
