About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • age from 8 to 15years
  • spherical equivalent(SE) was range from -1.00D to -5.00D
  • conform to the standard of wearing orthokeratology lens

Exclusion criteria

  • ocular diseases and systemic diseases

Treatment and study plan

Primary outcomes

  1. The change of axial length

    Time frame: The change of baseline and 1years

    The axial length was measured by AL-scan, its expressed in mm

Secondary outcomes

  1. Relative corneal refractive power shift(RCRPS)

    Time frame: up to 1 year

    The value of RCRPS was obtained and calculated from a corneal topography
