Method of using a corneal ring inlay |
摘要 |
A biocompatible corneal inlay ring apparatus for altering the curvature of the central optic zone of the cornea of the eye without intrusion into this optic zone, comprising a continuous ring of a fixed diameter greater than that of the optic zone, of a thickness and geometry such that the curvature of the central optic zone is flattened to an extent appropriate to the refractive correction desired, and of a composition having a refractive index within about 2.0% of that of the corneal tissue.
