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

Figure 1 Original diopter values and diopter increase in the two groups. A: Original diopter values. Of patients with low-degree myopia: Group A: n = 41, mean ± standard deviation (SD) = -1.82 ± 0.71; Group B: n = 59, mean ± SD = -1.71 ± 0.64. Of patients with moderate-degree myopia: Group A: n = 83, mean ± SD = -4.19 ± 0.82; Group B: n = 54, mean ± SD = -3.94 ± 0.62; B: Growth of diopter. Of patients with low-degree myopia: Group A: mean ± SD = -0.17 ± 0.34; Group B: mean ± SD = -0.88 ± 0.39. Of patients with moderate-degree myopia: Group A: mean ± SD = -0.13 ± 0.22; Group B: mean ± SD = -0.82 ± 0.37. N was the number of eyes. Boxes indicate the 1^st, 2^nd, and 3^rd quartile, whiskers represent the maximum and minimum value, and x indicates mean value. Statistically significant differences between patients treated differently were determined by a Mann-Whitney test (^cP ≤ 0.001). Group A: Myopia patients wearing orthokeratology lenses for 1 year; Group B: Myopia patients wearing frame glasses.
