Myopia control efficacy of individualised ocular refraction customisation spectacle lenses: A 2-year follow-up study.

ABSTRACT:

Purpose

To assess second-year myopia progression in children after a 1-year randomised controlled trial of individualised ocular refraction customisation (IORC) spectacle lenses, customised to each eye's peripheral refraction.

Methods

A total of 161 children were randomised to wear IORC lenses with high (+4.50 D, IORC-H), medium (+3.50 D, IORC-M) or low (+2.50 D, IORC-L) myopic defocus or single-vision lenses (SV). In year 2, all children received IORC-H, forming the IORC-H1/H2/H3/H4 groups, respectively. An external SV (eSV, n = 42) group was matched to year 2 baseline parameters. Spherical equivalent refraction (SER) and axial length (AL) were measured every 6 months.

Results

Compared with the eSV group (12-month mean [SD] changes: SER -0.56 [0.44] D, AL 0.32 [0.16]
