About

Our study has three parts has three parts, and the main aim of the study is to find out if corneal hysteresis was associated with myopia or even a predictor of myopia poor control predictor:

• Part 1 of our study: patients with anisomeropia whose spherical equivalent refraction as measured by cycloplegic autorefraction between the two eyes differ greater than 1.5 D.
• Part 2 of our study: Minus spherical equivalent refraction as measured by cycloplegic autorefraction.
• Part 3 of our study: patients with minus spherical equivalent refraction as measured by cycloplegic autorefraction who are under regular atropine for the treatment of myopia;patients who are prescribed with atropine treatment are in need of myopia control instead of for research interest

Enrollment: 100 estimated patients

Sex: All

Ages: 6 to 30 years old

Volunteers: Accepts Healthy Volunteers
