Retro-Illumination And Eye Front Surface Feature Registration For Corneal Topography And Ocular Wavefront System
US Patent:
2012024, Oct 4, 2012
Filed:
Mar 23, 2012
Appl. No.:
13/428688
Inventors:
Edwin J. Sarver - Carbondale IL, US
Donald R. Sanders - Elmhurst IL, US
Donald R. Sanders - Elmhurst IL, US
International Classification:
A61B 3/14
US Classification:
351206, 351246
Abstract:
A method of obtaining a retro-illumination image using the beacon from an ocular wavefront path and the camera for the corneal topography path of the combined system. A digital image of the retro-illuminated view of the IOL, iris pattern and sclera is obtained. An interactive display of the retro-illuminated image is presented to the user to allow them to identify the orientation marks on the IOL. These marks identify the orientation of the IOL and an overlay line can be used to display this orientation. In addition, a 360 degree overlay can be used to enhance the display of this orientation line.
Aspheric, Astigmatic, Multi-Focal Contact Lens With Asymmetric Point Spread Function
US Patent:
2012003, Feb 9, 2012
Filed:
Sep 20, 2011
Appl. No.:
13/237617
Inventors:
Edwin J. Sarver - Carbondale IL, US
Donald R. Sanders - Elmhurst IL, US
Donald R. Sanders - Elmhurst IL, US
International Classification:
G02C 7/04
US Classification:
351161
Abstract:
Presbyopic contact lenses that provide improved vision quality by use of optical zones which are not symmetric about the lens optical axis. The contact lens includes an optic body sized and configured to be received in an eye (or eyes) of a presbyopic patient having a front surface with a front optical center and a back surface with a back optical center, and having a lens optical axis intersecting the front surface at the front optical center and the back surface at the back optical center, and having optical zones which are not symmetric about the lens optical axis. The lens construction produces an asymmetric point spread function which enables any resulting asymmetric stray light to be steered in a predetermined direction.
Progressive Chromatic Aberration Corrected Ocular Lens
US Patent:
8061837, Nov 22, 2011
Filed:
May 20, 2009
Appl. No.:
12/469501
Inventors:
Edwin J. Sarver - Carbondale IL, US
Donald R. Sanders - Elmhurst IL, US
Donald R. Sanders - Elmhurst IL, US
International Classification:
G02C 7/10, G02C 7/02
US Classification:
351163, 351165, 351177
Abstract:
A method to reduce ocular chromatic aberrations using a lens or other spatial structure to selectively band-pass filter transmitted light of certain wavelengths. The ocular lens overcomes the negative effects of the wavelength band pass filter lenses while maintaining its ability to reduce the negative effects of chromatic aberration. The band-pass filter is applied in one or more concentric zones and or angular regions. The lens power is adjusted in concert with the band-pass filter wavelength to minimize aberrations. Variations include the application of the band-pass filter being applied to an angular region and no filter is applied to another. Alternatively the band-pass filter is not applied to one or more concentric ring regions and is applied to one or more angular regions. The band-pass filter can be applied to the surface of the lens or spatial structure, or applied to the lens material.
Method Of Designing Equal Conic Intraocular Lens
US Patent:
7350918, Apr 1, 2008
Filed:
Jun 13, 2006
Appl. No.:
11/452134
Inventors:
John Clough - St. Petersburg Beach FL, US
Edwin J. Sarver - Carbondale IL, US
Donald R. Sanders - Elmhurst IL, US
Edwin J. Sarver - Carbondale IL, US
Donald R. Sanders - Elmhurst IL, US
Assignee:
Lenstec Inc. - St. Petersburg FL
International Classification:
G02C 7/02
US Classification:
351177
Abstract:
An intraocular lens, with equal conic surfaces, is intended to replace the crystalline lens in the posterior chamber of a patient's eye, in particular after a cataract extraction. The lens provides optical power to focus objects onto a patient's retina. In addition the lens surfaces are shaped to reduce optical aberrations at the retina and are tolerant to lens tilt and decentration within the eye. The lens is designed to have zero longitudinal ray aberrations at a specific ray height.
