ABSTRACT:
Method and refractive errors of the eye are disclosed. Accelerated reshaping of the corneal tissue is accomplished by releasing enzyme(s) and/or other agents into the cornea which temporarily soften the cornea. The convex cornea is thereafter fitted with a rigid contact lens(es) which has a concave curvature that will correct the refractive error. The softened cornea then rapidly reshapes its convex curvature to the concave curvature of the contact lens rendering the eye emmetropic. The enzyme/agent then dissipates from the cornea as it "hardens" to retain the new emmetropic shape and the lens is removed.
