Home confinement's impact on myopia control by using orthokeratology in school-aged children

Abstract

Abstract Background： Home confinement during the epidemic has a significant impact on the lifestyle and behavior of school-aged children, who have exhibited an increase in the prevalence and development of myopia. Our research will look at how home confinement affects the effectiveness of orthokeratology in controlling myopia in school-aged children. Method: Data on axial length were gathered from school-aged children who had received orthokeratology before the outbreak, with phone follow-up visits to these patients to collect AL data after the epidemic. The entire data were separated into subgroups based on gender, age, and initial refraction, and the AL change for each period was calculated using the formula defined in our study. Finally, the acquired data will be examined using various statistical approaches, and the ideas of slow, moderate, and rapid myopia progression will be applied to our study. Result: A total of 258 study subjects met the requirements to be included in the study. We discovered that the fraction of rapid myopia growth increased during the epidemic and decreased afterward in each group. In addition, the Wilcoxon signed-rank test between the AL changes before and during the epidemic was found to be statistically significant in 171 subjects in the overall data. (P=0.041) In the high age group, the AL change before and during the epidemic、(P=0.033) the AL change before and after the epidemic (P=0.023) were found to be statistically significant. The AL change before and during the epidemic (P=0.035) was shown to be statistically significant in the moderate myopia group. Finally, we did not find statistically significant results for other groups. Conclusion: Home confinement does negatively affect myopia control with orthokeratology, and older children (13-17 years) were more likely to be affected than younger children (8-12 years), and there was no evidence to support this effect subsided even after the home confinement. Children with initial refraction of -3.25D to -5.0D were more susceptible than those with initial refraction of -0.5D to -3.0D.
