(Key: AL = axial length, CC = corneal curvature, CCT = central corneal thickness, GAT IOP = Goldmann applanation tonometry intraocular pressure, DCT IOP = dynamic contour tonometry intraocular pressure, IOPcc = Ocular response analyzer corneal compensated intraocular pressure, CH = corneal hysteresis, CRF = corneal response factor, † = significant at the p < 0.05 level).
