Filed:

Sep 23, 2005

Appl. No.:

11/234597

Inventors:

Daniel G. Brady - San Juan Capistrano CA, US
Tuyet H. Nguyen - Orange CA, US

Assignee:

Abbott Medical Optics Inc. - Santa Ana CA

International Classification:

A61F 2/16

US Classification:

623 612, 623912

Abstract:

An apparatus for sizing an intraocular lens and/or an ocular region of the eye of a subject, such as the anterior chamber, contains a sizing device and a measurement device. In one embodiment, the sizing device comprises a first leg having a first contact portion for operably engaging the ocular portion and a second leg having a second contact portion for operably engaging the ocular portion. The sizing device has a test geometry when placed within the ocular portion. The measurement device is adapted for determining a dimension of the sizing device based at least in part on the test geometry. The sizing device may also have a reference geometry when the sizing device in a reference condition. In certain embodiments, the difference between the reference geometry and the test geometry may be used for sizing the intraocular lens and/or the ocular portion.

International Classification:

A61F 2/16

US Classification:

623 646

Abstract:

An intraocular lens for implantation in a capsular bag of an eye includes an optic disposed about an optical axis and a haptic including a protruding portion disposed inside the optic. The optic has an anterior face and an opposing posterior face that are configured to provide a lens power. In response to an ocular force of the eye, the haptic transmits a force that alters one or more of a shape of the optic and an axial thickness of the optic. The protruding portion of the haptic has a refractive index that is equal to a refraction index of the optic for at least one wavelength within the visible spectrum.

Inventors:

Tuyet Nguyen - Orange CA, US

Assignee:

Allergan Sales, Inc. - Irvine CA

International Classification:

A61F002/14

US Classification:

623/005110, 606/107000, 623/906000

Abstract:

Apparatus and methods for holding and packaging intracorneal implants are provided. In one embodiment, the apparatus includes a holder body having a surface sized and adapted to carry an intracorneal implant, and a through hole extending through the surface, preferably sized and adapted to facilitate suction being applied to the intracorneal implant located in proximity to the surface. A cap member preferably is provided and is sized and adapted to be secured to the holder body so as to hold an intracorneal implant between the surface of the body and the cap member. Methods for packaging intracorneal implants and for providing intracorneal implants ready for use are provided and may involve using such apparatus.

Assignee:

Advanced Medical Optics, Inc. - Santa Ana CA

International Classification:

A61F 2/16

US Classification:

623 643, 623 611

Abstract:

An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The region of contact between the optic and the haptic extends into the edge of the optic, similar to the interface between a bicycle tire and the rim that holds it in place. The haptic may be stiffer than the optic. The haptic may have the same refractive index as the optic. The haptic may include a saddle-shaped portion in contact with the adjustable optic, with a convex profile along an optical axis; and a concave profile in a plane perpendicular to the optical axis.
