ABSTRACT

Background: After the home confinement that occurred with the new SARS-CoV2 disease, there has been a change in the use of new information and communication technologies (ICTs), increasing the visual demands in stages susceptible to the development of refractive defects.
Objectives: To evaluate how home confinement, and the use of ICTs may have influenced the distribution of refractive defects in children.
Materials and Methods: A cross-sectional analytical epidemiological study was performed including a convenience sample of 244 children divided into 2 independent groups: those who suffered home confinement (n=113) and those who did not (n=131). Personal and family history, type of school, school schedule, extracurricular activities, use of ICTs and homework were collected. Refraction under cycloplegia was explored. Subsequently, the distribution of refractive defects in both groups was examined.
Results: The distribution of refractive defects in the group that suffered confinement showed a lower number of emmetropic children and a higher number with astigmatism.
Conclusions: Home confinement after COVID-19 and changes in school and family education with respect to the use of ICTs could have been supposed a greater visual demand during the process of child emmetropization. In our study we observed fewer emmetropic children and more with astigmatism after confinement, which could result in an increased in the number of cases of myopia in the future.
