Abstract

Radial keratotomy (RK) is a refractive surgical procedure for correcting myopia, in which partial thickness incisions are made in the peripheral cornea. Previous clinical and experimental studies have shown that changes in corneal hydration have a significant impact on the results. It has been hypothesized that the in situ corneal stroma distributes tensile stress unequally throughout its thickness as a function of hydration. Efforts are being made to develop a theoretical model of the hydration phenomenon to determine if the anteroposterior in-plane stress-distribution of the cornea is a function of corneal hydration and how such changes in stress distribution would affect the results of RK.
