AIM: To investigate the dynamic changes of corneal hysteresis(CH)and corneal resistance factor(CRF)before and after orthokeratology(OK)in children with different degrees of myopia.METHODS: Totally 40 cases(80 eyes)of myopic children treated in our hospital from January 2019 to January 2020 were retrospectively analyzed. The subjects were divided into low-grade group and medium-grade group according to the spherical equivalent(SE)level. They were all treated with night wearing OK glasses. The LogMAR naked eye vision of the children was detected and recorded before and 1wk, 1, 6mo and 1a after wearing glasses. The levels of central corneal thickness(CCT)and axial length(AL)were monitored by ocular a-ultrasound, the SE level was measured by comprehensive optometry, the corneal curvature(K)was measured by corneal topography, the corneal compensated intraocular pressure(IOPcc)level was measured by ORA analyzer, and the values of CH and CRF were calculated at the same time.RESULTS:The naked visual acuity of LogMAR at 1wk, 1, 6mo and 1a after wearing glasses was significantly lower than that before wearing glasses(all P |
