Filed:

Mar 22, 2000

Appl. No.:

09/532910

Inventors:

Stephen W. Laguette - Laguna Niguel CA
Alan J. Lang - Long Beach CA
Robert E. Glick - Lake Forest CA

Assignee:

Allergan Sales, Inc. - Irvine CA

International Classification:

A61F 216

US Classification:

623 637, 623 64, 623 643, 623 647

Abstract:

Intraocular lenses include an optic adapted to focus light toward a retina of an eye and a movement assembly coupled to the optic. In one embodiment, the optic has a far vision correction power and the movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic, preferably upon radial compression by a capsular bag of the eye. The optic preferably vaults anteriorly relative to the movement assembly. The movement assembly preferably circumscribes the optic and includes a member having a proximal end portion coupled to the optic and a distal end portion extending away from the optic and adapted to contact a capsular bag of the eye.

International Classification:

A61F 216

US Classification:

623 637, 623 627, 623 628, 623 639

Abstract:

Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a single optical power IOL adapted for accommodating movement.

Assignee:

Advanced Medical Optics, Inc. - Santa Ana CA

International Classification:

A61F 216

US Classification:

623 624, 623 628

Abstract:

An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens is biased for distance vision and the second ophthalmic lens is biased for near vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient following removal of the natural lens.

US Classification:

623 628, 623 624, 623 654

Abstract:

An ophthalmic lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first ophthalmic lens is biased for distance vision and the second ophthalmic lens is biased for intermediate vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient without removal of the natural lens.

Appl. No.:

09/565036

Inventors:

Alan J. Lang - Long Beach CA
Arlene Gwon - Newport Beach CA

Assignee:

Advanced Medical Optics, Inc. - Santa Ana CA

International Classification:

A61F 216

US Classification:

623 628, 623 632, 623 634

Abstract:

An intraocular lens for implantation in an eye of a patient includes a multifocal optic and a movement assembly. The optic has maximum add power which is less than the add power required for full near vision for a pseudophakic eye. The movement assembly is coupled to the optic and is adapted to cooperate with the eye of the patient to effect accommodating movement of the optic in the eye. Lens systems including two optics and two movement assemblies are also provided. The intraocular lenses and lens systems are particularly useful when implanted in the eyes of a patient after removal of the natural lenses.

International Classification:

A61F 216

US Classification:

623 628, 623 632

Abstract:

An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens has a first baseline diopter power for distance vision correction and the second ophthalmic lens has a second baseline diopter power for other than distance vision correction. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient or has natural lenses or following removal of the natural lenses.

Assignee:

Advanced Medical Optics, Inc. - Santa Ana CA

International Classification:

A61F 216

US Classification:

623 637, 623 649

Abstract:

An intraocular lens includes an optic for focusing light and a movement assembly coupled to the optic. The movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic. The movement assembly includes a plurality of movement members and a suspension structure. The movement members are coupled to a periphery of the optic. The suspension structure is coupled to the movement members and is adapted to be in contact with a peripheral region of a capsular bag of an eye. The movement members are adapted to convert radial movement of the suspension structure caused by movement of the capsular bag to axial movement of the optic. The movement members are also adapted to amplify the radial movement of the suspension structure so that the optic moves axially a greater distance than the distance moved radially by the suspension structure.

Assignee:

International Classification:

A61B 302

US Classification:

351243

Abstract:

Apparatus for measuring accommodation of a lens in an eye includes a target, a Badal lens, and a viewing aperture, where the Badal lens and the viewing aperture are positioned so that when the target moves towards or away from the lens, the apparent size of the target remains constant to a subject looking in the viewing aperture regardless of the distance the target moves. The apparatus may be provided in a compact housing and may include a mirror placed in the housing so that the viewing aperture can be placed away from the optical axis of the lens. The apparatus includes a controller to control the movement of the target. The apparatus measures the accommodation of a lens based on the distance the target moves during an examination. Methods of measuring accommodation of a lens in an eye of a subject are also disclosed.
