Novel application of multispectral refraction topography in the observation of myopic control effect by orthokeratology lens in adolescents

Figure 4 Scatterplots showing the relationship between total retinal defocus value and defocus values of peripheral retina. A: Showing retinal defocus values (RDVs) of patients with low-degree myopia in group A (R² = 0.877); B: Showing RDVs of patients with low-degree myopia in group B (R² = 0.668); C: Showing RDVs of patients with moderate-degree myopia in group A (R² = 0.618); D: Showing RDVs of patients with moderate-degree myopia in group B (R² = 0.498).
