Light Adjustable Aberration Conjugator

View page
US Patent:
6721043, Apr 13, 2004
Filed:
Oct 11, 2001
Appl. No.:
09/977857
Inventors:
Ben C. Platt - Stevenson Ranch CA
Christian A. Sandstedt - Pasadena CA
Assignee:
Calhoun Vision, Inc. - Pasadena CA
International Classification:
G01B 900
US Classification:
356124
Abstract:
A method of correcting aberrations in an optical system by applying a light adjustable aberration conjugator layer to a component of the system, determining the nature of the aberration, applying radiation to the conjugator layer such as to change the refraction and/or shape of the conjugator layer to compensate for the aberration, and locking in the desired optical property.

Application Of Wavefront Sensor To Lenses Capable Of Post-Fabrication Power Modification

View page
US Patent:
6749632, Jun 15, 2004
Filed:
Mar 20, 2001
Appl. No.:
09/813598
Inventors:
Christian A. Sandstedt - Pasadena CA
Jagdish M. Jethmalani - Pasadena CA
Robert H. Grubbs - South Pasadena CA
Julia A. Kornfield - Pasadena CA
Daniel M. Schwartz - San Francisco CA
Robert Maloney - Pacific Palisades CA
Assignee:
California Institute of Technology - Pasadena CA
The Regents of the University of California - Oakland CA
Calhoun Vision, Inc. - Pasadena CA
International Classification:
A61F 216
US Classification:
623 622, 623 656
Abstract:
The present invention relates to methods of implementing an optical element having a refraction modulating composition. The methods include using a wavefront sensor to provide an optical measurement of the optical element. The present invention also relates to systems comprising an optical element having a refraction modulating composition and a wavefront sensor.

Lenses Capable Of Post-Fabrication Modulus Change

View page
US Patent:
6813097, Nov 2, 2004
Filed:
Aug 15, 2002
Appl. No.:
10/223086
Inventors:
Jagdish M. Jethmalani - Pasadena CA
Robert H. Grubbs - South Pasadena CA
Julia A. Kornfield - Pasadena CA
Daniel M. Schwartz - San Francisco CA
Christian A. Sandstedt - Pasadena CA
Eric Pape - Pasadena CA
Assignee:
California Institute of Technology - Pasadena CA
The Regents of the University of California - Oakland CA
International Classification:
G02B 310
US Classification:
359721, 359722, 359723, 359724, 359642, 359665, 359666, 359667
Abstract:
Novel optical elements are provided which are capable of post fabrication modifications. Specifically, the invention includes lenses, such as intraocular lens, which can undergo changes in storage modulus after fabrication.

Lenses Capable Of Post-Fabrication Power Modification

View page
US Patent:
6824266, Nov 30, 2004
Filed:
Feb 3, 2003
Appl. No.:
10/358065
Inventors:
Jagdish M. Jethmalani - Pasadena CA
Daniel M. Schwartz - San Francisco CA
Julia A. Kornfield - Pasadena CA
Robert H. Grubbs - South Pasadena CA
Christian A. Sandstedt - Pasadena CA
Assignee:
California Institute of Technology - Pasadena CA
Regents of the University of California - Oakland CA
International Classification:
G02C 702
US Classification:
351159, 623 611
Abstract:
The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion of the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields as data storage means and as medical lenses, particularly intraocular lenses, respectively.

Delivery System For Post-Operative Power Adjustment Of Adjustable Lens

View page
US Patent:
6905641, Jun 14, 2005
Filed:
Sep 26, 2001
Appl. No.:
09/964786
Inventors:
Ben C. Platt - Stevenson Ranch CA, US
Christian A. Sandstedt - Pasadena CA, US
James A. Ebel - Glendale CA, US
Assignee:
Calhoun Vision, Inc. - Pasadena CA
International Classification:
B29D011/00
US Classification:
264 138, 264 401, 264409
Abstract:
A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate intensity pattern by first measuring aberrations in the optical system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that will null the aberrations. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated.

Assignee:
Calhoun Vision, Inc. - Pasadena CA
International Classification:
G01B009/00
US Classification:
356124, 359642, 359838
Abstract:
A method of correcting aberrations in an optical system by applying a light adjustable aberration conjugator layer to a component of the system, determining the nature of the aberration, applying radiation to the conjugator layer such as to change the refraction and/or shape of the conjugator layer to compensate for the aberration, and locking in the desired optical property.

US Patent:
7105110, Sep 12, 2006
Filed:
Apr 25, 2005
Appl. No.:
11/114861
Inventors:
Ben C. Platt - Stevenson Ranch CA, US
Christian A. Sandstedt - Pasadena CA, US
James A. Ebel - Glendale CA, US
Assignee:
Calhoun Vision, Inc. - Pasadena CA
International Classification:
B29D 11/00
US Classification:
264 138, 264 401, 264409
Abstract:
A method and instrument to irradiate a light adjustable lens, for example, inside a human eye, with an appropriate amount of radiation in an appropriate pattern by measuring aberrations in the system containing the lens; aligning a source of the modifying radiation so as to impinge the radiation onto the lens in a pattern that corresponds to the aberration; and controlling the quantity of the impinging radiation whereby to decrease the aberration. The quantity of the impinging radiation is controlled by controlling the intensity and duration of the irradiation. The pattern is controlled and monitored while the lens is irradiated.
