Polychromatic MTF analysis (mean ± SD) at the fields of 0°–30° at a maximum spatial frequency of 60 cycles per millimeter. The MTF values were averaged between the tangential and sagittal directions. (a–i) The MTF analysis at different pupil sizes (2 mm, 4 mm, and 6 mm) and for groups of different initial myopia, including mild myopia (0 to − 3 D), medium myopia (− 3 to − 6 D), and high myopia (over − 6 D).
