Study of Atropine Therapeutic Effect on Myopic Progression
- Conditions
- ChildrenMyopia
- Interventions
- Registration Number
- NCT05529056
- Lead Sponsor
- LitePharmTech Co., Ltd.
- Brief Summary
This study is to evaluate the therapeutic effect and safety of LPTAT in children with myopia.
- Detailed Description
The primary objective is to evaluate the superiority of LPTAT to placebo in slowing myopia progression through the change of SE(Spherical Equivalent), which is measured by cycloplegic autorefraction after 12-month treatment.
