    Abstract: A contact lens is fitted to a cornea of a patient's eye to gradually alter the patient's cornea during continued wear to reshape the cornea to reduce the myopic condition. The contact lens has a plurality of zones that includes an optical zone, a fitting zone, one or more facilitate zones, an alignment zone and a peripheral zone. The one or more facilitate zones are utilized to redistribute cornea tissue to cause the cornea to have a flattened central portion surrounded by a steep mid-peripheral ring.

    Abstract: An accelerated method of orthokeratology includes the steps of softening of the cornea with a softening agent, applying a mold to reshape the cornea to a desired anterior curvature, and rapidly restabilizing or "fixing" the corneal tissues so that the cornea retains its new configuration. A chemical softening agent, such as glutaric anhydride is applied to the cornea to soften the cornea, after which a specially designed mold of predetermined curvature and configuration is applied to the cornea. Slight downward pressure is applied to the mold for a predetermined period of time to re-shape the cornea. The mold is maintained in position while a stabilizing agent, such as a UV light source, is positioned above the mold. The stabilizing agent, i.e. UV light, is applied to the cornea for a predetermined time, wherein the stabilizing agent immediately restabilizes the corneal tissue so that the cornea immediately retains its shape upon removal of the mold. The stabilization process can also be used for patients having already undergone traditional orthokeratology to eliminate the need to continue wearing a retainer to maintain the shape of the cornea.

    Abstract: A contact lens (400) and orthokeratology method for correcting a patient's vision. The contact lens (400) has an optical zone (406) for compressing a central potion of a cornea. The contact lens (400) also includes an alignment zone (410) that has curvature less than a measured curvature of a portion of the cornea under the alignment zone (410). This curvature of the alignment zone (410) creates a large corneal bearing area (402) that provides a centering force to maintain the optical zone (406) substantially at the center of corneal visual axis. While wearing the contact lens (400), forces from the alignment zone (410) and optical zone (406) cooperate to flatten the central portion of the cornea by maintaining compression at the central portion of the cornea, resulting in visual correction.

    Abstract: A contact lens for use on a patient's eye with an asymmetric aspheric cornea, the lens having an anterior surface, a posterior surface and a base, the posterior surface having a peripheral portion which is asymmetric and aspherical and at least coextensive with the base of the lens. The peripheral portion asymmetrically and aspherically matching a corresponding peripheral portion of the cornea which lies under the peripheral portion of the lens when the lens is worn in the patient's eye. The contact lens is not substantially greater in diameter than said cornea. The process for manufacturing the lens uses three-dimensional topographic data (including elevation data) from a multiplicity of points on the cornea. The data is used to shape at least the peripheral portion of the posterior surface of the lens to cause it to conform to and/or match the corresponding surface of the cornea.

    Abstract: A multiple focus corneal contact lens for use in treating myopia by controlled corneal molding. The lens includes an asymmetric central zone which provides multiple focusing capability to correct both near and far vision. The tear zone is located concentrically around the central zone. The tear zone is integral with the central zone and has a radius of curvature which is smaller than the central zone. The lens also includes a peripheral zone located concentrically around the tear zone wherein the peripheral zone has a radius of curvature equal to or greater than the central zone.

    Abstract: Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include a deformable inner portion and a deformable peripheral portion. When disposed over the optical region of an eye, the inner portion is configured so that engagement of the posterior surface against the eye deforms the posterior surface so that the posterior surface has a shape diverging form the refractive shape of the epithelium when viewing with the eye through the ophthalmic lens. The rigidity of the inner portion is greater than the rigidity of the peripheral portion and the ophthalmic lenses are configured to allow movement relative to the eye upon blinking of the eye and to be substantially centered on the optical region of the cornea following the blinking of the eye. Methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses are also disclosed.
