Patent number: 7771053Abstract: A selectively marked contact lens having, in one aspect, marks in an optical zone region on a surface thereof and, in another aspect, different marks outside an optical zone region of the lens, for an in-vivo lens. With the lens in-vivo, the subject's eye is illuminated and the lens is imaged. A fast algorithm is used to determine the mark coordinates in relation to a measured pupil coordinate to determine position and/or orientation of the contact lens. A wavefront aberration measurement can also be obtained simultaneously with the contact lens position measurement, as well as pupil size. A fast algorithm provides for online measurements; i.e., at a repetition rate of 10 Hz or greater, over a selected time interval. Blinking periods are determined and anomalous lens position and/or wavefront information is discarded. A most frequently occurring wavefront and/or contact lens position/orientation is determined over the selected time interval.Type: GrantFiled: July 22, 2004Date of Patent: August 10, 2010Assignee: Bausch & Lomb IncorporatedInventors: Hans-Joachim Polland, Stefan Seitz, Kristian Hohla, Gerhard Youssefi, Ernst Hegels, Birte Jansen, Christoph Sappel

Publication number: 20060158612Abstract: A topographical parameter measuring device and method utilizes a technique based on wave front reconstruction according to, e.g., Hartmann-Shack principles. The device includes a planar illuminator comprising a known array of illumination sources for projecting a light spot pattern onto a target surface. A CCD camera detects the positions of the reflected image spots in a manner similar to that in a Hartmann-Shack wave front sensor. The displacements of the light spots from reference coordinates are indicative of the slope of the surface at the plurality of sample points. A computational component is used to fit the slope data of a reference surface and the target surface to a polynomial, for example, a Zernike polynomial. The polynomial, properly weighted with the calculated coefficients, provides a continuous mapping of the elevation of the target surface.Type: ApplicationFiled: December 19, 2005Publication date: July 20, 2006Inventors: Hans-Joachim Polland, Stefan Seitz ( Franzke), Kristian Hohla
