The Biomechanical Response of the Cornea in Orthokeratology

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Orthokeratology has been widely used to control myopia, but the mechanism is still unknown. To further investigate the underlying mechanism of corneal reshaping using orthokeratology lenses via the finite element method, numerical models with different ...
