Changes and Diurnal Variation of Visual Quality after Orthokeratology in Myopic Children.

Conclusions: Orthokeratology can effectively improve UCVA and high spatial frequency CSF by decreasing the low-order aberrations. However, MTF and CSF at low spatial frequency decreased because of the increase of intraocular scattering and high-order aberrations. Meanwhile, CSF at high spatial frequency fluctuates significantly at two times during the same day after 1 month orthokeratology. PMID: 30410793 [PubMed]
