A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

An intraocular lens for providing enhanced vision includes an optic having a clear aperture having an outer diameter. The optic has opposing first and second surfaces disposed about an optical axis, the first surface including a cross-sectional profile. The optic further includes central and outer zones that fill the entire clear aperture of the optic. The central zone is disposed about the optical axis having an outer diameter, the profile in the vicinity of the central zone having a constant radius of curvature or a radius of curvature that increases with increasing radius from the optical axis. The outer zone is disposed about the central zone, the profile in the outer zone having a base curvature with a base radius of curvature and a center of curvature, the profile in the outer zone characterized in that, as the distance from the optical axis increases, the distance from the center of curvature of the base curvature also increases. The central zone and the outer zone.

The present invention is a phakic intraocular lens for implantation between an iris and a crystalline lens. The phakic intraocular lens includes a diffraction grating 5 disposed in a lens central part 2 and having circular, coaxial grooves formed thereon, and a support part 3 disposed outside the diffraction grating 5 and supporting the diffraction grating 5. A hole 6 is formed in the center of the diffraction grating 5.

An accommodating intraocular artificial lens with variable optical power, comprising two optical elements which are adapted to mutually shift in a direction perpendicular to the optical axis wherein the optical elements have such a shape that the optical elements exhibit, in combination, different optical powers at different relative positions. Flanges are adapted to position the anterior section of the haptics in the sulcus of the eye or, alternatively, the ciliary body is enclosed by a combination of anterior and posterior flanges. Also disclosed are methods to provide for an accommodating intraocular lens which is adjustable post-implant to ensure emmetropia of the eye.

An ophthalmic device is provided for a patient that has a basic prescription for distant vision, the ophthalmic device including a primary optic and a supplemental optic. The primary optic is configured for placement in the eye and has a base optical power configured to substantially provide the basic prescription. The supplemental optic has an optical power that is less than the optical power of the primary optic and is configured to provide, in combination with the primary optic, a combined optical power that provides the basic prescription of the patient. In addition, at least one surface of the primary optic is configured to deform in response to an ocular force so as to modify the combined optical power by at least 1 Diopter. The ophthalmic device may further include a movement assembly operably coupled to the primary optic that is structured to cooperate with the eye to effect accommodating deformation of the primary optic in response to an ocular force produced by the eye. The movement assembly may also be configured to provide accommodating axial movement of the primary optic.

An apparatus to treat a cataract where the cataractous lens is pierced and the resulting opening is mechanically maintained using a lens system device such as a cylindrical lens, tubular lens, pinhole device, a stent or similar small diameter device, or where the device itself is the lens. The resulting passageway for visible light created in the cataractous lens allows light to better reach the retina, thus improving vision. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. Intraocular lenses may also be used in concert with this invention. The apparatus and related methods can be applied to humans as well as animals.

A lens configured for implantation into an eye of a human can include an optic including transparent material. The optic can have an anterior surface and a posterior surface. Each of the anterior surface and the posterior surface can have a surface vertex. The optic can have an optical axis through the surface vertices. The lens can also include at least one haptic disposed with respect to the optic to affix the optic in the eye when implanted therein. The anterior and posterior surfaces can include aspheric surfaces. The posterior surface can have an aspheric shape that comprises a biconic offset by perturbations comprising an aspheric higher order function of radial distance from the optical axis. The posterior surface can have an absolute value of ratio R.sub.x/R.sub.y between 0 and 100 and an absolute value of ratio k.sub.x/k.sub.y between 0 and 100.

An ophthalmic lens comprising a main lens part, a recessed part, an optical center, and an optical axis through the optical center. The main lens part has at least one boundary with the recessed part and has an optical power of between about −20 to about +35 diopter. The recessed part is positioned at a distance of less than 2 mm from the optical center and includes a near part having a relative diopter of about +1.0 to about +5.0 with respect to the optical power of the main lens part. The boundary or boundaries of the recessed lens part with the main lens part form a blending part or blending parts, are shaped to refract light away from the optical axis, and have a curvature resulting in a loss of light, within a circle with a diameter of 4 mm around the optical center, of less than about 15%.

A system for ophthalmic surgery on an eye includes: a pulsed laser which produces a treatment beam; an OCT imaging assembly capable of creating a continuous depth profile of the eye; an optical scanning system configured to position a focal zone of the treatment beam to a targeted location in three dimensions in one or more floaters in the posterior pole. The system also includes one or more controllers programmed to automatically scan tissues of the patient's eye with the imaging assembly; identify one or more boundaries of the one or more floaters based at least in part on the image data; iii. identify one or more treatment regions based upon the boundaries; and operate the optical scanning system with the pulsed laser to produce a treatment beam directed in a pattern based on the one or more treatment regions.
