Brief summary

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

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.
