Abstract
During and after PRK procedures on a cornea, both the deformation of the surface and the stress changes in the cornea should be carefully observed. This paper will report some clinical examples showing qualitatively the stress distribution changes in PRK operated cornea and the calculated retinal images due to the deformation of the corneal surfaces.
