System And Method For Predictive Ophthalmic Correction

View page
US Patent:
7130835, Oct 31, 2006
Filed:
Dec 20, 2002
Appl. No.:
10/327229
Inventors:
Ian G. Cox - Honeoye Falls NY, US
Barry T. Eagan - Salt Lake City UT, US
Howard Markman - Honeoye NY, US
Kamal Sarbadhikari - Penfield NY, US
Kristian Hohla - Vaterstetten, DE
Gerhard Youssefi - Landshut, DE
Craig Schoof - Sammamish WA, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
A61B 18/18
G06F 15/18
US Classification:
706 21, 606 4, 606 5
Abstract:
A system and method for providing a predictive outcome in the form of a predictive best instruction for a therapeutic ophthalmic correction of a patient's vision defects. The predictive best instruction is derived from prospective therapeutic-outcome-influencing, new information that is analyzed in conjunction with optimized, historical therapeutic-outcome information. The instruction is preferably an optimized, custom, photoablative algorithm for driving a photoablative, excimer laser. The instruction can be provided on a fee basis.

Moiré Aberrometer

US Patent:
7341348, Mar 11, 2008
Filed:
Mar 25, 2003
Appl. No.:
10/397099
Inventors:
Barry T. Eagan - Salt Lake City UT, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
A61B 3/10
US Classification:
351221, 351212
Abstract:
An improved moiré deflectometer device for measuring a wavefront aberration of an optical system includes a light source for illuminating a surface area of the optical system, an optical relay system for directing scattered light to a deflectometer component that converts the wavefront into a moiré fringe pattern, a sensor/camera assembly for imaging and displaying the exit pupil of the optical system and the moiré fringe pattern, and a fringe pattern to calculate the wavefront aberration of the optical system, being improved by an illumination source for illuminating the exit pupil of the optical system; and an alignment system cooperating with the illumination source in such a manner to consistently and accurately align a measurement axis of the device to the optical system. An associated method is also disclosed.

Apparatus And Method For Determining A Position Of An Eye

View page
US Patent:
7478908, Jan 20, 2009
Filed:
Sep 27, 2006
Appl. No.:
11/528130
Inventors:
Ming Lai - Webster NY, US
Barry T. Eagan - Spencerport NY, US
Lloyd G. Allred - Rochester NY, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
A61B 3/14
A61B 3/10
US Classification:
351206, 351221
Abstract:
An apparatus for determining a position of a subject's cornea, comprising a camera, a first illumination apparatus adapted to provide a first beam of light and a first diffuse portion of light that are coincident, and a second illumination apparatus adapted to provide a second beam of light and a second diffuse portion of light, that are coincident. In some embodiments, the first, second, third and fourth images are disposed on the midpoints of a square, when a cornea is located along an optical axis of camera.

Eye Length Measurement Apparatus

View page
US Patent:
7800759, Sep 21, 2010
Filed:
Dec 11, 2007
Appl. No.:
11/954146
Inventors:
Ming Lai - Webster NY, US
Daozhi Wang - Rochester NY, US
Barry T. Eagan - Spencerport NY, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
G01B 11/02
US Classification:
356497
Abstract:
An interferometric axial eye length measurement apparatus having a light source adapted to produce a beam of partially coherent light, a first mirror and a second mirror disposed in the reference arm, and a processor adapted to control at least the second mirror such that a corneal interference peak and a second interference peak have a non-zero separation. There is at least one variable delay optical element having a delay signal, wherein the delay signal corresponding to a region between the corneal interference peak and second interference peak is substantially linear.

Aberrometer Having Reduced Noise

View page
US Patent:
7874674, Jan 25, 2011
Filed:
Dec 12, 2007
Appl. No.:
11/955003
Inventors:
Lloyd G. Allred - Rochester NY, US
Barry T. Eagan - Spencerport NY, US
International Classification:
A61B 3/10
US Classification:
351221, 351246
Abstract:
Methods and apparatus for facilitating determination of centroids of image spots in an image containing an array of image spots generated by an aberrometer, the image comprising a first plurality of pixels each pixel having a corresponding intensity value, the method comprising calculating an average intensity value for a second plurality of pixels in a perimeter around a pixel, the average calculated using a subset of the second plurality exclusive of at least a portion of the pixels in the perimeter.

Prismatic Ocular Device And Personal Video Display Device Incorporating Same

View page
US Patent:
7901072, Mar 8, 2011
Filed:
Nov 13, 2009
Appl. No.:
12/618456
Inventors:
Barry T. Eagan - Spencerport NY, US
Paul J. Travers - Honeoye Falls NY, US
Theodore K. Ricks - Rochester NY, US
Robert J. Schultz - Farmington NY, US
Assignee:
Vuzix Corporation - Rochester NY
International Classification:
G02C 1/00
US Classification:
351158, 359379
Abstract:
An ocular device includes a housing, a rotatable ring, a first prism fixed in the rotatable ring, an indexable ring and a second prism fixed in the indexable ring. The housing has a stepped inner profile defining first and second circular tracks in the housing, the tracks being concentric about a rotational axis. The rotatable ring is disposed in the first circular track and is freely rotatable about the rotational axis with respect to the housing. The indexable ring is disposed in the second circular track and is indexable about the rotational axis.

Power-Adjusted Aberrometer

US Patent:
7980698, Jul 19, 2011
Filed:
Nov 19, 2008
Appl. No.:
12/273720
Inventors:
Lloyd G. Allred - Bountiful UT, US
Jeffrey B. McBeth - Rochester NY, US
Barry Eagan - Spencerport NY, US
Assignee:
Bausch & Lomb Incorporated - Rochester NY
International Classification:
A61B 3/00
A61B 3/10
US Classification:
351246, 351221
Abstract:
Aspects of the invention are directed to apparatus and methods for automatically setting a power level of light emitted by a light source; illuminating a retina of a patient with the light emitted by the light source; receiving, at a sensor, light reflected from the retina of the patient; providing a signal based upon the received light; determining whether the signal meets one or more signal quality criteria; automatically setting a second power level of light emitted by the light source; and repeating the steps of illuminating the patient's eye, receiving reflected light, providing the signal, and determining whether the signal meets the signal quality criteria. In some embodiments, setting the second power level is performed in response to determining whether the signal meets the signal criteria. In still other embodiments, the method comprises selecting an operating power based upon the signal quality criteria.
