Adhesion is safe to the refractive surgeries: A theoretical analysis

Abstract

Adhesion behavior, existed on the damaged interface, was responsible for the safety and stability of the post-operative cornea refer to the refractive surgeries. In this study, we inferred that the force loss generated by the post-operative cornea must do not surpass the interfacial adhesion force of the cornea. In case of that, the corneal flap (or cap) would trend to separate from the residual stromal bed, and then became a threat to the visual health of the corrected myopic patient. According to this inference, we derived the theoretical maximum ablated ratio, which was well matched with the empirically clinical safety standard employing the commonly programmed optical zone.
