Study summary

The purpose of this trial is to investigate the safety and efficacy of MyopiaX - a digital treatment intended to slow the progression of myopia in children and adolescents.

Read the detailed description

The present study is a multicentric, randomized, controlled, single masked trial to investigate the signals of effect, the safety and tolerability of MyopiaX in slowing the progression of myopia.

The trial consists of 12 months treatment period. The first 6 months participants will be treated either with MyopiaX or with myopia control spectacles. During the second half of the trial, participants treated with MyopiaX will receive the myopia control spectacles in addition. 81 children and adolescent aged 6 - 12 years will be included in the trial. Eligible subjects will be randomly assigned in a 2:1 ratio to either the MyopiaX or the myopia control spectacles group.
