Summary

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
