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

Interventions

Type	Name	Description
DEVICE	Orthokeratology with aspheric wide inversion zone design in the optical zone	An orthokeratology lens with an altered optical zone design is designed for an aspherical wide inversion arc in the optical zone
DEVICE	Orthokeratology with traditional spherical design in the optical zone	Subjects wore the orthokeratology with traditional spherical design in the optical zone
