A method of predicting clinical performance of an ophthalmic optical correction using simulation by imaging a series of objects of different sizes by each of a plurality of eye optical systems, each of the eye optical systems including the ophthalmic optical correction, the method providing an output value representing the resolution and contrast performance of the optical design at that vergence for the eye optical systems.

Use of an optical system simulating behavior of human eye to generate retinal images and an image quality metric to evaluate same

A device for measuring depth of field of an eye optical system that includes a lens Badal having positive optical power, a positioning apparatus adapted to maintain the eye optical system on the image side of the lens at a first focal plane of the lens and a multi-vergency target that provides a plurality of objects that are simultaneously viewable, through the lens, by the eye optical system.

Method and apparatus for determining depth of focus of an eye optical system

Methods and apparatus for improving vision incorporate the effects of biodynamical and biomechanical (biological) responses of the eye. The eye produces a biological response to trauma, such as a LASIK keratectomy or other necessary traumatic procedure in preparation for refractive surgery. By observing the biological response, a prospective treatment to correct higher order aberrations is adjusted to compensate for the biological effects. An improved photorefractive surgery system incorporates one or more suitable diagnostic devices that provide biological response information in such a manner that the patient need not change position from that assumed for the surgical procedure.

Method and system for improving vision

Contact lenses, such as prism ballasted toric lenses, having anterior and posterior surfaces related by way of non-axisymmetric thickness variation can exhibit a third-order aberration, particularly vertical coma. A wavefront modifier, such as an aspheric surface modification, is incorporated into the lenses to at least partially compensate for the wavefront aberration associated with the non-axisymmetric thickness variation. A magnitude of the modifications can be adjusted to set a target value for any remaining wavefront aberration of the lenses based on a population-wide goal.

Contact lens with high-order compensation for non-axisymmetric structure

A system and method for providing a predictive outcome in the form of a predictive best instruction for a therapeutic ophthalmic correction of a patient's vision defects. The predictive best instruction is derived from prospective therapeutic-outcome-influencing, new information that is analyzed in conjunction with optimized, historical therapeutic-outcome information. The instruction is preferably an optimized, custom, photoablative algorithm for driving a photoablative, excimer laser. The instruction can be provided on a fee basis.

System and method for predictive ophthalmic correction

A method of designing a contact lens or other correction for providing presbyopia correction to a patient relies on wavefront aberration measurement data for providing a best form correction. Preferably the correction is in the form of a multifocal translating style alternating vision contact lens or a simultaneous vision style correcting lens. A method for designing a correction for improving a person's vision is directed to correcting higher order aberrations in such a manner that a residual amount of the higher-order rotationally symmetric aberration is greater than a residual amount of the higher-order rotationally asymmetric aberration after the correction. A design method according to the invention is directed to correcting asymmetric higher order aberrations induced by decentering of a multifocal contact lens that has residual spherical aberration which provides increased depth of field.

Presbyopic vision improvement

A method and mold assembly to control the polymerization of a molded article. In one embodiment, an amorphous posterior mold comprising a non-critical surface having a controlled radius of curvature is used to produce molded articles. In an alternate embodiment, ophthalmic lenses are produced using a posterior mold in which the concave surface of the non-critical surface is filled with a liquid having a similar refractive index as the mold material. In still another embodiment, a positive lens is placed at a predetermined distance adjacent to the mold assembly to alter the irradiation path to the mold assembly. In still another embodiment, a positive lens is placed within the concave surface of the posterior lens.

Wavefront aberration measurements measured in response to design parameter changes in a contact lens, for example, are used to design and prescribe contact lenses offering improved vision quality. In-situ optical performance of trial lenses provides real-time, objectively determined data as a design model for the lenses. Lenses designed by the inventive process are described as well as a method for using an aberrometer to design and prescribe contact lenses.

Contact lens and method for fitting and design

A method and business architecture for providing vision correction to a patient involves obtaining wavefront aberration measurement information and, optionally, patient history data, ordering data, dispensing data, billing data, and other information, from the patient; transmitting the various data to respective appropriate platforms, e.g., transmitting the wavefront aberration information to a custom lens supply platform; producing a custom lens for the patient; and delivering a custom lens to the patient in a personalized manner. The method further involves fitting and measurement processes including in-situ lens shaping and custom manufacture of contact lenses, IOLs, inlays or onlays by laser ablation, lathing, casting/molding and machining. Business architectures according to the invention include segregating vision correction method steps into contractual, revenue generating business transactions.

Customized vision correction method and business

A method for obtaining contact lenses having optimized visual acuity involves providing the anterior surface or the posterior surface of the contact lens with a conic section having a shape factor value within the range of about 0.3 to 2.0, the shape factor value being selected so as to adjust spherical aberration in the central optical zone to a value within the range of about &minus;0.2 diopter to about &minus;0.6 diopter and to a value that provides optimal visual acuity.

Contact lenses providing improved visual acuity

A contact lens includes an anterior surface and a posterior surface where the posterior surface includes a central zone and a peripheral zone, where the radius of curvature of the central zone is at least 0.4 mm, and preferably at least 0.6 mm, greater than the radius of curvature of the peripheral zone.
