Abstract:
AIM: To compare the control effects between toric-designed orthokeratology and spherical orthokeratology on adolescents with moderate-to-low myopia.METHODS: The clinical data of 169 adolescents(290 eyes)with moderate-to-low myopia in Jiayuan Outpatient Department of Shanghai Demu Ophthalmology from July 2020 to June 2021 were analyzed retrospectively. The patients were divided into toric group and spherical group according to the type of orthokeratology, with 81 cases(135 eyes)and 88 cases(155 eyes)respectively. The changes of visual acuity and ocular axis before and after treatment were recorded to evaluate the therapeutic effect.RESULTS: The uncorrected visual acuity of both groups significantly improved at 1a after treatment(P<0.01), and the axial length increased compared to that before treatment(P<0.01). But there were no significant differences in uncorrected visual acuity(0.014±0.043, 0.017±0.047LogMAR)and axial growth(0.18±0.22, 0.19±0.22mm)between the two groups(P>0.05).CONCLUSION: Both toric-designed orthokeratology and spherical orthokeratology can improve the uncorrected visual acuity of adolescents with low-to-moderate myopia, and there is no significant difference in controlling effect on myopia.
