Clinical trials

This study will assess the optimal performance characteristics of optical defocus on transient changes in axial length with Kubota Glass, using a randomized, double-masked, 5-treatment, 5-period crossover design with contralateral eye control.

This is a bilateral, dispensing, masked, randomized clinical trial. Myopic children will be randomly assigned to one of the following: (1) Investigational clinical prototype (CP1) device without atropine, (2) Investigational CP1 device with daily instillation of 0.01% atropine, or (3) daily instillation of 0.01% atropine without use of the investigational CP1 device. Primary endpoint: Difference in the 12-month change of cycloplegic spherical refractive error and axial length between each of the three treatment groups.
