Summary

The purpose of this study is to determine the efficacy of different lens treatments (normal spectacle lens, ortho-K, & Myovision) on myopia control in Chinese adolescent patients.

Clinical Details

Official title: Randomized Controlled Trial of Different Lens Treatments on Chinese Adolescent Myopia

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change of Ocular Axial Length

Secondary outcome: Change of Spherical Equivalent Refraction

Detailed description: Different lens treatments include normal spectacle lens, orthokeratology, and Myovision (a specially designed spectacle lens commercially available with peripheral defocus controlled as relative myopia). This study is to evaluate the efficacy of these three methods in controlling myopia progression. Until now, there is no sufficient clinical evidences to compare different lens treatments.
