摘要： Systems and methods for manufacturing a wavefront-customized contact lens. The systems include: (1) an optical instrument for measuring ocular imperfections of a patient's eye; (2) a computer for designing a mold and pin design used for manufacturing a wavefront-customized contact lens that corrects the ocular imperfections; (3) a fabrication machine for fabricating a wavefront-customized mold that includes corrections for the ocular imperfections; and (4) a manufacturing equipment for manufacturing a wavefront-customized contact lenses that uses the wavefront-customized mold; wherein the wavefront-customized mold design and wavefront-guided contact lens manufacturing are uniquely customized for each patient's eye. The optical means can be a wavefront aberrometer with, or without, a profilometer and/or an Optical Coherence Tomography (OCT) module. The wavefront-customized contact lens can be a soft contact lens or a rigid, gas permeable contact lens.

摘要： The present invention provides a method for designing and making a customized ophthalmic lens, such as a contact lens or an intraocular lens, capable of correcting high-order aberrations of an eye. The posterior surface of the customized contact lens is designed to accommodate the corneal topography of an eye. The design of the customized ophthalmic lens is evaluated and optimized in an optimizing routine using a computational model eye that reproduces the aberrations and corneal topography of an eye. The present invention also provides a system and method for characterizing the optical metrology of a customized ophthalmic lens that is designed to correct aberrations of an eye. Furthermore, the present invention provides a business model and method for placing an order for a pair of customized ophthalmic lenses.

摘要： A method for making a finished aspheric single vision, spherical or aspheric bifocal, multifocal or progressive addition contact lens includes the step of fitting a patient requiring a near correction with a single vision spherical or aspheric contact lens for optimal distance vision and comfortable fit. If desired, the patient is then over-refracted to determine the required near correction to be embodied in the contact lens. A portion of the optic corresponding to the center location of the pupil is marked on the convex side of the optic to form an optical preform. In some instances, the lens may not stabilize on the cornea to a suitable degree. Thus, it is often desirable to stabilize the contact lens, either prior to placing the lens on the patient or after rotation is observed on the cornea of the patent. Observation of rotation on the patient's cornea is enhanced by means of the mark that is used to designate the center of the patient's pupil. The optical preform is removed from the eye of the patient and the concave side of the optical preform is marked at a position corresponding to the mark on the convex side that denotes the center of the pupil. The mark disposed on the convex side of the optical preform is removed. A specified volume of polymerizable resin is placed in a mold embodying the required correction, which includes an add power zone so that the resin fills the intervening space between the mold and the optical preform. The add power zone is aligned on the optical preform to a predetermined position with respect to the mark on the optical preform designating the center of the pupil. The resin is then polymerized the optical preform is demolded to obtain the finished contact lens having the required correction.

摘要： An optical device comprising a lens configured to be disposed in an eye. The lens is configured to contact a sclera of the eye and have a clearance above a cornea of the eye when disposed in the eye. The lens comprises a back surface that comprises at least one non-symmetrical feature that is configured to engage a corresponding feature on the eye. The lens is configured to be rotationally stable in use based on the at least one non-symmetrical feature on the back surface of the lens.

摘要： A multifocal contact lens customized for a patient includes a central portion having a concave aspherical posterior surface of a standardized eccentricity and an annular portion connected to the central portion. The central portion also has a convex anterior surface with a power curve customized to the patient. The annular portion is provided with an aspheric annular cornea-fitting posterior surface and has an outer edge with a centralized apex, whereby the annular portion may be formed at the outer edge to be entrainable by a patient's eyelid to shift the lens relative to the patient's eye to vary which portion of the power curve is used during vision. The contact lenses according to the invention may be rigid or soft (hydrogels).
