Corneal topography difference map after Ortho-K lens wear for one year. a One of the myopic eyes from the AL elongation group. b One of the myopic eyes from the AL reduction group. The center coordinates of the treatment zone area are [− 0.60, − 0.33] and [0, − 0.01], respectively, and the radii of the treatment zone area are 2.14 mm and 1.53 mm, respectively
