Patent number: 9072434Abstract: One exemplary embodiment is a method for determining an ophthalmic prescription. An examination room is lighted to simulate daytime viewing and a conventional eye chart is used as a visual stimulus. A first corrective spherical lens power is determined by varying spherical lens power and identifying when perceived vision is best. The examination room is kept dark to simulate nighttime viewing conditions. The visual stimulus utilized is a white point source on a dark background, or a self illuminated symbol on a dark background. A second corrective spherical lens powered is determined by varying spherical lens power and identifying when perceived vision is best. An ophthalmic prescription such as one or more lenses, one or more surgical corrections or a combinations thereof is provided including a first corrective component including the first preferred spherical lens power, and a second corrective component including the second preferred spherical lens power.Type: GrantFiled: August 19, 2014Date of Patent: July 7, 2015Assignee: INDIANA UNIVERSITY RESEARCH & TECHNOLOGY CORPORATIONInventors: Larry N. Thibos, Jose Manuel Gonzalez-Meijome, Norberto Lopez-Gil

Patent number: 7357509Abstract: Several metrics to predict the subjective impact of the eye's wavefront aberrations are presented. The metrics can be based on RMS wavefront errors or slopes, the area of the critical pupil, a curvature parameter, the point spread function, the optical transfer function, or the like. Other techniques include the fitting of a sphero-cylindrical surface, the use of multivariate metrics, and customization of the metric for patient characteristics such as age.Type: GrantFiled: April 28, 2004Date of Patent: April 15, 2008Assignees: University of Rochester, University of Houston, Indiana UniversityInventors: David R.

Patent number: 6905210Abstract: Methods, systems, and media relating the display of scattering and/or absorption characteristics of an optical medium. For scattering measurements, a Hartmann-Shack calibration image of a measurement system is acquired to define a first plurality of point spread functions. A Hartmann-Shack test image of the medium is acquired to define a second plurality of point spread functions. A shift is determined between the test image and the calibration image. A point spread of each of the second plurality of point spread functions is measured, each of the second plurality of point spread functions including a component due to optical aberration of the medium and a component due to scatter. The component due to optical aberration is determined using the shift. The component due to optical aberration is deconvolved to determine the component due to scatter. A display of the local scattering characteristics is generated using the component due to scatter.Type: GrantFiled: December 1, 2003Date of Patent: June 14, 2005Assignees: Board of Regents, The University of Texas System, Advanced Research and Technology InstituteInventors: Raymond A.
