Summary
Effects on Ocular Parameters of Myopic Eyes After Orthokeratology in Myopic Children
Detailed description
1.The primary objective of the current study is to investigate changes in uncorrected visual acuity, diopter, accommodation, peripheral refraction, IOP, tear film quality, corneal thickness, corneal topography, corneal biomechanical parameters, objective optical quality, corneal and conjunctiva sensitivity and choroidal thickness for children with different diopters after wearing orthokeratology lenses; 2. Through measure long-term changes of these parameters, including corneal topography, axial length, peripheral refraction, objective optical quality and choroidal thickness, to explore occurrence and development regularity of myopia.
