Publication number: 20100097569Abstract: An intraocular lens for providing a subject with vision at various distances includes an optic having a first surface with a first shape, an opposing second surface with a second shape, a multifocal refractive profile, and one or more diffractive portions. The optic may include at least one multifocal diffractive profile. In some embodiments, multifocal diffractive and the multifocal refractive profiles are disposed on different, distinct, or non-overlapping portions or apertures of the optic. Alternatively, portions of the multifocal diffractive profiles and the multifocal refractive profiles may overlap within a common aperture or zone of the optic.Type: ApplicationFiled: October 20, 2008Publication date: April 22, 2010Applicant: Advanced Medical Optics, Inc.Inventors: Hendrik A. Weeber, Patricia Ann Piers, Mark H. Bandhauer, Marrie H. Van Der Mooren, Huawei Zhao

Publication number: 20100014049Abstract: An ophthalmic lens for providing a plurality of foci includes an optic having an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens has a first region and a second region. The first region has a first refractive optical power and includes a first base curvature having a finite first radius of curvature and a first phase plate having at least one diffraction order with a diffractive optical power. The first region is configured for forming a first focus and a second focus. The second region has a second refractive optical power and includes a second base curvature having a finite second radius of curvature that is different from the first radius of curvature and a second phase plate having at least one diffraction order with a diffractive optical power. The second region is configured for forming a third focus that is between the first focus and the second focus.Type: ApplicationFiled: September 24, 2009Publication date: January 21, 2010Applicant: Abbott Medical Optics Inc.Inventors: Mark H.

Publication number: 20090195748Abstract: An ophthalmic lens for providing a plurality of foci has an optic including an anterior surface, a posterior surface, and an optical axis. The ophthalmic lens further includes a central phase plate, an intermediate phase plate surrounding the central phase plate, and an outer refractive region. The central phase plate comprises a first base curvature having a first radius of curvature and is configured such that the lens is able to direct light to a first focus and a second focus corresponding different diffraction orders of the phase plate. The intermediate phase plate is configured to change the overall resultant distribution of light directed to the second focus. The outer refractive region has no diffractive optical power and surrounds the intermediate phase plate. The outer refractive region is configured to direct light to the second focus and has an aspheric shape configured to reduce an optical aberration.Type: ApplicationFiled: November 25, 2008Publication date: August 6, 2009Applicant: Advanced Medical Optics, Inc.Inventors: Mark H. Bandhauer, Alan J. Lang

Patent number: 7455404Abstract: An ophthalmic lens for providing a plurality of foci has an optic comprising an anterior surface, a posterior surface, and an optical axis. The optic has a first region and a second region. The first region has a refractive optical power and comprises a multifocal phase plate for forming a first focus and a second focus. The second region has a refractive optical power and comprises a monofocal phase plate for forming a third focus. The multifocal phase plate and the monofocal phase plate may be disposed on first and second base curvatures, respectively, that may have different radii of curvature. The ophthalmic lens may also have an intermediate phase plate located between the multifocal phase plate and the monofocal phase plate, the intermediate phase plate comprising a third plurality of echelettes disposed on a third base curvature having a third radius of curvature.Type: GrantFiled: October 25, 2005Date of Patent: November 25, 2008Assignee: Advanced Medical Optics, Inc.Inventors: Mark H. Bandhauer, Alan J. Lang

Publication number: 20080114301Abstract: The present invention is generally directed to improved methods, devices, and systems for eye surgery. In some embodiments, the invention may provide new and/or improved devices, systems, and methods for detecting surgical fluids in a fluidics cassette, particularly cassettes which are used to couple an eye treatment probe to an eye treatment console. Rather than relaying on internal reflection by a gas-liquid interface, the fluid detection techniques described herein may make use of the changes in propagation of light through a portion of the holding tank when the portion varies between empty and full. For example, light may propagate directly through the holding tank portion when there is no surgical fluid, but may be directed away from a light detector when the portion of the holding tank is filled with surgical fluid.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Applicant: Advanced Medical Optics, Inc.Inventors: Mark H. Bandhauer, John I. Muri, David King

Publication number: 20040230300Abstract: An accommodating intraocular lens system including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more haptic elements. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more haptic elements. Each haptic element is formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The accommodating intraocular lens system is so designed with specific flexibility characteristics to facilitate axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force.Type: ApplicationFiled: June 18, 2004Publication date: November 18, 2004Inventors: Mark H. Bandhauer, George F. Green, Donald Carrol Stenger, Michael T. Landreville

Publication number: 20020173845Abstract: An intraocular lens with low surface-glare. The intraocular lens is constructed to preferably have a equi-biconvex optic form and a positive anterior optic surface radius of curvature less than 20 mm or greater than 33 mm. The intraocular lens of the present invention having the described construction minimizes or eliminates unwanted optical images and/or glare.Type: ApplicationFiled: May 21, 2001Publication date: November 21, 2002Inventors: Mark H.
