Summary

In this study, we intend to enroll orthokeratology subjects aged 8-18 years old with binocular myopia up to and including -4.00 D. They were randomly selected to wear both orthokeratology of different designs, one with an aspheric wide inversion zone design in the optical zone and the other with a traditional spherical curved segment design, and to investigate the differences between these two lenses in terms of their effectiveness in myopia retardation, defocus, and aberration.

Conditions

  • Myopia
