  • Accurate determination of intraocular pressure and characterization of mechanical properties of the cornea
    Patent number: 8070679
    Abstract: A computer-implemented method for accurate determination of intraocular pressure (IOP) and characterization of mechanical properties of a cornea is provided that includes measuring a cornea with a probe tonometer to produce at least force versus displacement data over a range of applied forces; and forming a model of corneal constitutive parameters, with a computer having a processor, based on the data obtained by the probe tonometer to more accurately determine IOP and characterize mechanical properties of the cornea, wherein the computer is coupled with the probe tonometer.
    Type: Grant
    Filed: July 21, 2008
    Date of Patent: December 6, 2011
    Assignee: The Board of Trustees of the University of Illinois
    Inventors: Jamshid Ghaboussi, David A. Pecknold, Youssef Hashash, Tae-Hyun Kwon

  • Method and program product for solid mechanics modelling workbench and dynamic display
    Patent number: 7356449
    Abstract: An embodiment of a method and a program product of the invention has steps of selecting a model from a plurality of models in a model library, with at least one of the models being a constitutive model. Load data and load path data are input to the model to generate model output. The output is then displayed in a graphical format.
