| Abstract: | ABSTRACT The effect of contact lens wear on the electrical characteristics of the corneal epithelium is reviewed. Both soft and hard lenses reduce the transcortical potential, with hard lenses having a greater effect. Recovery of the potential is slower following hard contact lens wear. This paper suggests that hard contact lenses cause more disruption to the electrical resistance and electromotive forces in the corneal epithelium. The mechanisms are discussed using an electrical circuit model of the cornea. |
