Myopia control efficacy of spectacle lenses with highly aspherical lenslets: results of a 5-year follow-up study.

ABSTRACT:

Purpose

To evaluate myopia control efficacy in myopic children wearing spectacle lenses with highly aspherical lenslets (HAL) for 5 years.

Methods

This is a randomized, double-masked extended trial. Myopic children aged 8 to 13 years who were originally allocated to the HAL group in the 2-year clinical trial. The HAL group underwent a 5-year assessment for myopia progression using cycloplegic spherical equivalent refraction (SER) and axial length (AL). An extrapolated single-vision spectacle lenses (ESVL) group was used as a control group. The 5-year myopia progression and axial elongation of the ESVL group was calculated based on the 2-year data from the single-vision spectacle lenses group in the same clinical trial, and the data for the following 3 years was estimated by
