Randomized Trial of Soft Contact Lenses with Novel Ring Focus for Controlling Myopia Progression.

ABSTRACT:

Purpose

To evaluate efficacy and vision with 2 prototype myopia control soft contact lenses with noncoaxial ring-focus designs (for enhancing efficacy [EE] and enhancing vision [EV]) compared with dual-focus (DF) and single-vision (SV) designs.

Design

Multicenter, 6-month, randomized, controlled, double-masked clinical trial.

Participants

One hundred ninety-nine myopic (-0.75 diopters [D] to -4.50 D) children aged 7 to 12 years.

Methods

Participants were randomized with stratification into myopia control (EE, EV, or DF) or SV arms at 9 clinical sites in 3 countries. Postcycloplegia axial length (AL) and spherical equivalent autorefraction (SECAR) were measured at baseline and 26 weeks. Axial length was also measured without cycloplegia at baseline, 1, 4, 13, an
