Effect of Increased Power and Asphericity of Highly Aspherical Lenslets on Myopia Control Efficacy: A Contralateral Crossover Study.

ABSTRACT:

Purpose

The study aims to evaluate whether the myopia control efficacy of spectacle lenses with Highly Aspherical Lenslet Target (H.A.L.T.) technology could be further improved by a combined increase of power and asphericity of lenslets.

Methods

Fifty Singaporean myopic children aged 6 to 10 years were enrolled in a randomized, contralateral, crossover clinical trial. Two different myopia control spectacle lenses were tested: lenses with H.A.L.T. technology and lenses with maximized H.A.L.T. (H.A.L.T. MAX) technology. One group (N = 25) was assigned to wear H.A.L.T. MAX on the right eye and H.A.L.T. on the left eye, and the other group (N = 25) to wear the opposite combination for 6 months. The combinations were switched for the next 6 months. The primary outcome was the cha
