Accommodative Intraocular Lens
US Patent:
6695881, Feb 24, 2004
Filed:
Apr 29, 2002
Appl. No.:
10/134877
Inventors:
Qun Peng - Arlington TX
Yin Yang - Arlington TX
Xiaoxiao Zhang - Fort Worth TX
Yin Yang - Arlington TX
Xiaoxiao Zhang - Fort Worth TX
Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61F 216
US Classification:
623 634, 623 639
Abstract:
A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly against the posterior capsule. The periphery of the first optic contains a pair of clasps. The second optic is located anteriorly to the first optic and is of a positive power. The peripheral edge of the second optic contains a pair of locking arms that fit into the clasps contained on the periphery of the first optic to lock the second optic onto the first optic, but allow for rotation of the arms within the clasps. Hinge structures on the locking arms allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.

Method Of Calculating The Required Lens Power For An Opthalmic Implant
US Patent:
7476248, Jan 13, 2009
Filed:
Apr 6, 2004
Appl. No.:
10/819020

Alcon, Inc. - Hunenberg
International Classification:
A61F 2/14
A61F 2/16
A61F 2/16
US Classification:
623 511, 623 611
Abstract:
A method for calculating the required cylindrical power of a toric implant by using both the measured pre-operative corneal/ocular astigmatism and the predicted surgically-induced astigmatism. The post-operative corneal/ocular astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required spherocylindrical refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.
Pseudo-Accommodative Iol Having Multiple Diffractive Patterns
US Patent:
7481532, Jan 27, 2009
Filed:
Feb 9, 2006

Assignee:

International Classification:
G02C 7/06
A61F 2/16
A61F 2/16
US Classification:
351171, 623 63
Abstract:
In one aspect, a trifocal ophthalmic lens is disclosed that includes an optic having a surface that comprises at least one trifocal diffractive pattern and at least one bifocal diffractive pattern such that the bifocal pattern provides near and far vision and the trifocal pattern generates near, far, and intermediate vision. For example, the trifocal pattern can provide near, far, and intermediate foci such that the near and far foci are substantially coincident, respectively, with a near and a far focus of the bifocal pattern. In this manner, the trifocal and bifocal patterns collectively provide near, intermediate, and far foci (or focal regions) corresponding, respectively, to the near, intermediate and far vision.
Correction Of Higher Order Aberrations In Intraocular Lenses
US Patent:

Assignee:
Alcon, Inc. - Hunenberg
International Classification:
A61F 2/16
US Classification:
623 611, 623 41
Abstract:
In one aspect, the present invention provides a method of designing an intraocular lens (IOL) to address variations of at least one ocular parameter in a population of patient eyes. The method can include establishing at least one eye model in which the ocular parameter can be varied over a range exhibited by the population. The eye model can be employed to evaluate a plurality of IOL designs in correcting visual acuity for eyes in the patient population. An IOL design that provides a best fit for visual performance over at least a portion of the parameter range can then be selected.

Intermediate Vision With Phakic Multifocal Optics Utilizing Residual Accommodations
US Patent:
8100527, Jan 24, 2012
Filed:
Jan 11, 2008
Appl. No.:
12/522949
Inventors:
Xin Hong - Arlington TX, US

Assignee:
Novartis AG - Basel
International Classification:
G02C 7/02
A61F 2/16
A61F 2/16
US Classification:
351159, 351161, 623 63, 623 636
Abstract:
In one aspect, the present invention provides a method of correcting vision, which comprises determining a residual accommodation exhibited by a natural, crystalline lens of an eye, and selecting a multifocal intraocular lens (IOL), which exhibits a far-focus optical power (e. g. , in a range of about −15 to about +50 Diopters (D)) and an add power (e. g. , in a range of about 1 D to about 4 D), for implantation in the eye while retaining the natural lens. The add power of the IOL is selected as a function of the residual accommodation such that a combination of the IOL and the natural lens provides a visual contrast greater than about 10% at a spatial frequency of about 20 cycles/degree for viewing objects at a distance greater than about 30 cm from the eye.
