Treatment zone size (a), treatment zone decentration distance (b) and polar plot displaying the treatment zone decentration direction (c) in the 5.0 mm-BOZD OK and the 6.2 mm-BOZD OK groups. The range between 0° and 360° is similar to the meridian degree set on a corneal topography map, and the small circle represents the center of the treatment zone (c). Error bars represent the standard deviation (a and b). BOZD, back optic zone diameter; OK, orthokeratology. **P < 0.01
