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
