Study Details

Study Description

Brief 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
