Refraction and Ocular Biometry of Preschool Children in Shanghai, China.

Conclusion: Chinese children aged 3 to 6 years in the Shanghai area were mostly mildly hyperopic, with a low prevalence of myopia. Refractive astigmatism for children may be relatively stable throughout the preschool stage. Astigmatism was significantly associated with refractive error. PMID: 29692930 [PubMed]
