Axial Length (Axial Elongation)
Axial Length was measured with the IOLMaster at baseline, and then every 6 months throughout the course of the study. Five measurements were collected for each eye at each visit and the average of the 5 measurements were used for the analysis. Higher values of axial elongation indicate worse vision.
Time frame: Baseline and every 6 months post-baseline up to 3 years
Spherical Equivalent Refraction
Spherical Equivalent Refraction was computed from the sphero-cylindrical refraction measured with an open-field auto refractor. The median of 3 repeated measurements, each of which was the average of 3 consecutive readings, was used for the analysis. Higher values of spherical refraction indicate progression in Myopia.
Time frame: Baseline and every 6 months post-baseline up to 3 years
