Fig. 7From: Comparison of two different orthokeratology lenses and defocus incorporated soft contact (DISC) lens in controlling myopia progressionAxial elongation over one year in low myopic (SER: − 1.00 D to − 2.50 D) and moderate myopic (SER: − 2.50 D and over) groups wearing 5.0 mm-BOZD OK, 6.2 mm-BOZD OK, DISC, and SCL. SER, spherical equivalent refraction; BOZD, back optic zone diameter; OK, orthokeratology; DISC, defocus incorporated soft contact; SCL, soft contact lens. Error bars represent the standard deviation. *P < 0.05, ***P < 0.001Back to article page
