Correlation between retinal defocus distribution and axial growth in myopic children wearing orthokeratology lenses [PDF]

BMC Ophthalmology
Introduction The purpose was to investigate the refractive status of different retinal regions in myopic children treated by orthokeratology (ortho-k) and its relationship with axial elongation. Methods This was a cross-sectional study.
