Adaptability of myopic children to progressive addition lenses with a modified fitting protocol in the Correction of Myopia Evaluation Trial (COMET).

Purpose: The purpose of this study was to evaluate the adaptability of myopic children participating in the Correction of Myopia Evaluation Trial (COMET) to the use of progressive addition lenses (PALs) with a modified fitting protocol of setting the distance fitting cross 4 mm above the pupil center.

Methods: COMET was a multicenter, randomized clinical trial to evaluate whether PALs vs. single-vision lenses (SVLs) slowed the rate of progression in children with juvenile-onset myopia over 3 years.
