Effects of orthokeratology on biological parameters and visual quality of adolescents with low-grade corneal astigmatism myopia

Objective To investigate the effects of orthokeratology on biological parameters and visual quality of adolescents with low-grade corneal astigmatism myopia. Patients and methods In this study, a total of 41 myopic adolescents were prescribed with orthokeratology glasses in our hospital from February 2018 to March 2019 and voluntarily cooperated with relevant examinations before and after wearing orthokeratology lenses. Patients' uncorrected distant visual acuity (UCVA-D), uncorrected near visual acuity (UCVA-N) and naked eye near stereoacuity before wearing glasses, 1 month, and 3 months after wearing glasses were observed. The corneal astigmatism of patients was observed. The corneal endothelial cell density was observed. The dynamic adjustment function (NP, AF, NRA, PRA) values of patients were observed. The comparison of biological indexes in different time periods was observed. The changes of corneal curvature before wearing orthokeratology lens, 1 month and 3 months after wearing orthokeratology lens were observed. Results There were significant changes of patients 1 month after wearing orthokeratology lenses (p Conclusions The use of orthokeratology can greatly correct myopia patients' vision, improve their stereoscopic vision, control the progression of myopia, and improve their eye regulation, which is of high safety and great short-term effect.
