  • providing a covering comprising;

    an inner portion characterized by an inner rigidity and a thickness, and comprising an upper surface and a lower surface; and

    an outer portion characterized by an outer rigidity, and comprising an upper surface, a lower surface, and a peripheral portion;

    wherein the inner rigidity is from 1.2E-6 Pa-m3 to 3.1E-3 Pa-m3 and the outer rigidity is from 5.4E-9 Pa-m3 to 1.5E-4 Pa-m3;

    applying the covering to an eye of a patient following the refractive surgery by;

    centering the covering on the cornea; and

    applying a pressure against the covering to flex the covering against the cornea, wherein,the covering being applied to the eye, the inner portion of the covering conforms to the optical region of cornea and to the anterior surface of the flap; and
