One-year changes in axial length and refraction in children using low-level red light and distant-image screen for myopia control: a randomized controlled trial.

ABSTRACT:

Objective

To assess the efficacy and safety of 650-nm low-level red light (RL) and distant-image therapy (DIT) for myopia.

Methods

A randomized clinical trial. Children aged 8-10 years with a spherical equivalent error (SER) ranging from -1 to -1.5 diopters (D) were enrolled, and were randomly allocated to the following group: RL, DIT, RL + DIT, and control in a 1:1:1:1 ratio. The primary outcomes were changes in SER and axial length (AL).

Results

One hundred and sixteen children randomized, girls accounted for 45.69% (53/116). The median one-year changes in SER were 0.21D (inter-quartile range, IQR: -0.03D to 0.46D), -0.06D (-0.32D to 0.19D), -0.08D (-0.31D to 0.14D), and -0.30D (-0.51D to -0.09D), respectively, for the RL + DIT, RL, DIT, and the control group.
