An ophthalmological implant including an imaging optical element, and a haptic with a haptic root. Also, a corresponding method for producing an ophthalmological implant and a characterization system for identifying an ophthalmological implant for example an intraocular lens. The implant includes an unambiguous label and hence an unambiguous and reliable identification option. The label is not able to be mixed-up and is possible with minimal additional technical outlay. The implant includes a rotationally symmetric structural code of identification data of the ophthalmological implant arranged on the haptic root and/or the region of the haptic proximate the haptic root. Also, a method for producing an ophthalmological implant, in which the implant receives, directly during or after the forming, a rotationally symmetric structural code of identification data.

An intraocular lens assembly is used in cataract surgery. An intraocular lens assembly (100) has a haptic (102) having a ring (106), a plurality of arcuate arms (108), and a plurality of haptic arm bases (110). Each of the arms (108) is connected with the ring (106) by a respective base (110). An optic (104) has at least two pairs of opposed holes (112). The holes (112) are positioned in the close proximity with an outer peripheral edge of the optic (104). The optic (104) is removably positionable in the haptic (102) by a snap fit lock forming the intraocular lens assembly. The intraocular lens assembly (100) has a first unlocked position wherein haptic (102) is dissembled from the optic (104), and a second locked position wherein the optic (104) is snap fitted in the haptic (102).

A diffractive multifocal lens is disclosed, comprising an optical element having at least one diffractive surface, the surface profile comprising a plurality of annular concentric zones. The optical thickness of the surface profile changes monotonically with radius within each zone, while a distinct step in optical thickness at the junction between adjacent zones defines a step height. The step heights for respective zones may differ from one zone to another periodically so as to tailor diffraction order efficiencies of the optical element. In one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights. By plotting a topographical representation of the diffraction efficiencies resulting from such a surface profile, step heights may be optimized to direct a desired level of light power into the diffraction orders corresponding to near, intermediate, and distance vision, thereby optimizing the performance of the multifocal lens.

An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

The present invention generally relates to a system for two-photon or multi-photon irradiating an artificial lens, preferably an intraocular lens preferably arranged within an eye of a patient and a method for locally adjusting a polarizability and/or a refractive index of an artificial lens preferably an intraocular lens preferably arranged within an eye of a patient. The method relates in particular to fabrication of optical profiles by adjusting polarizability through two- or multi-photon processes in a non-destructive manner.

An apparatus has a central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens.

The lens body is formed from a substantially transparent material and the central aperture includes a darkened perimeter. The darkened perimeter of the central aperture includes a darkened internal wall extending through the lens body from an anterior surface to a posterior surface of the lens body.

An ophthalmic lens may comprise a posterior optic surface and an anterior optic surface, which may comprise a central optic, a peripheral optic, and a capsule rim separating the central optic and the peripheral optic. An optic edge may couple the posterior optic surface to the peripheral optic. The capsule rim may be symmetric or asymmetric in various embodiments. In more particular embodiments, the capsule rim may form a surface at an angle of at least ninety (90) degrees to the peripheral optic. In some embodiments, the central optic may comprise an optic axis, and the capsule rim may form a surface that is substantially parallel to the optic axis.
