Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Orthokeratology lens is an effective method for myopia control. This study analyzed the relationship between the relative corneal refractive power shift and change of axial length in adolescents with orthokeratology lens.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Orthokeratology lens is an effective method for myopia control. This study aimed to investigate the relationship between the relative corneal refractive power shift and changes of axial length in adolescents with orthokeratology lens in 1 year. Other factors that may affect axial growth were also analyzed.
