Main finding: At 3 years, mean change in spherical equivalent refraction and axial length was 59% (-0.73 dioptres) and 52% (0.32mm) less than in the control group respectively.
Study characteristics:
Name: “A 3-year Randomized Clinical Trial of MiSight Lenses for Myopia Control”
Purpose: To evaluate the effectiveness of MiSight soft contact lenses in juvenile-onset myopic progression
Type: Randomised controlled Trial
Condition: Myopia

-No prior contact lens wear
n=109 patients
Intervention:
Group 1: MiSight 1-day contact lens daily
Group 2: Control contact lens
There were no serious ocular adverse events reported.
