Abstract:Objective: To study the subjective visual quality of myopic children wearing the focus incorporated multiple segment (DIMS) lenses, and compare them to orthokeratology lenses (OK) and single vision (SV) spectacle lenses. Methods: In this prospective clinical research, a total of 93 myopic patients were recruited from July to October 2020 in Nanning Aier Eye Hospital. Thirty-one children (31 eyes) wore multiple focus segment lenses, 32 children (32 eyes) wore orthokeratology lenses and 30 children (30 eyes) wore single vision lenses prescribed in the Optometry Center. After wearing corrective lenses for 1 month, the Oculus binocular function tester was used to check the three groups of eye parameters such as full vision, contrast sensitivity, glare, mesopic functions and stereopsis in the 3 groups. Data were analyzed by one-way analysis of variance, Chi-square test, rank sum test, and Spearman correlation. Results: There was no statistically significant difference in the near and far visual acuity of the three groups of patients from the baseline period to one month after wearing the glasses. There was no significant difference in near and far stereoscopic acuity among the three groups, and the number of children with 600 " -200" stereoscopic acuity in the three groups showed the least differences. Contrast sensitivity among the three groups was statistically significant (F=17.96, P<0.001). The MFS group had the largest number of qualified cases with 20 (65%) subjects with a contrast sensitivity of ≤ 15%. With or without glare, the pass rate for the contrast levels (1:2.7, 1:2.0) of the MFS group were higher than that of both the OK lens group and SV group. The contrast level of 1:2.0 showed a more obvious difference. The difference was statistically significant (P<0.001). Stereoscopic acuity was negatively correlated with age (r=-0.30, P=0.008), but not correlated with refractive power. There was a strong correlation between glare and contrast sensitivity (r=0.64, P<0.001), and no correlation with gender, age, or refraction analysis. Conclusion: Compared to orthokeratology and single vision spectacle lenses, the multiple focus segment lens can provide better subjective vision quality, good comfort and safety
