Linear mixed-effects model adjusted for age, sex, intraocular pressure, and central corneal thickness. NM = nonmyopia; MM = mild-to -moderate nonaxial myopia; HM = high axial myopia; mild CDA = corneal deformation amplitude; ICA = inward corneal applanation length; OCA = outward corneal applanation length; ICV = inward corneal velocity; OCV = outward corneal velocity; PD = peak distance.
