To Evaluate the Efficacy and Safety of Aspherical Soft Contact Lens in Myopia Control
January 19, 2020 updated by: APP Vision Care Inc.
A Prospective Randomized Control Study to Evaluate the Effect of Ticon Aspherical Daily Disposable Soft Contact Lens on Myopia Control
The objective of this study is to demonstrate that the Ticon Aspherical Daily Disposable Soft Contact Lens could retard myopia progress in youth
Study Overview
Detailed Description
This study is designed as a prospective, multicenter, randomized, double blinded, controlled, paired-eye comparison study.
At least 60 evaluable subjects with myopia progression ≧ 0.75 D in the past 12 months will be recruited from 2 study sites.
The experimental soft contact lens with aspherical design (Ticon Aspherical) will be randomly assigned to either the right eye or the left eye of the subject , then the fellow eye will be assigned a control lens with a single vision distance (SVD) soft contact lens (Ticon).
Both lenses will be worn at least 8 hours a day, 5 days a week for 1 year.
All lenses will be replaced every day.
Brief assessment of the clinical findings will be followed up for one year at 1 day, 1 week, 1, 3, 6, 9, 12 months upon allocation.
The primary efficacy outcome is change in spherical equivalent refraction (SER) measured by cycloplegic autorefraction over 12 months.
The secondary outcome is change in axial eye length (AXL) measured over 12 months.
The secondary outcome measure is used to corroborate any changes in SER
