This study was aimed to evaluate the effects of different Orthokeratology，including the size of central optical zone and the height of peripheral reverse curve, on myopia control and visual quality.

Detailed description

This study was aimed to evaluate the effects of different Orthokeratology on myopia control and visual quality. The different optical zone of Orthokeratology lens was divided into 4 groups, ranged from 5.5 mm to 6 mm. And the control group subjects with the single glasses was included. The effectiveness of Orthokeratology was measured by axial length progression. The visual quality of subjects was evaluated by a questionnaire, contrast sensitivity and wavefront aberration.

Conditions
