    摘要: A two-dimensional reflection pattern suitable for corneal topography that uses sinusoidal profiles of both intensity and color values. The technique provides a more robust image processing due to the ability to apply digital band pass filters, continuous data for improved surface reconstruction, and the ability to directly measure the meridian of the reflection pattern source point when the corneal surface normal does not lie in the meridian of the measurement instrument.

    摘要: A method and apparatus related to enhancing corneal accommodation to address the effect of presbyopia. Corneal/scleral topology measurements in accommodating and non-accommodating states are indicative of a presbyopic subject's nominal corneal accommodative power. A desired accommodative power intended to improve on the effect of presbyopia can be determined, suggesting a selective biomechanical intervention in the corneal structure outside of the optical zone to create flexure regions. These flexure regions would allow enhanced corneal accommodation upon presentation of an accommodating stimulus. Intervention could be in the form of, for example, corneal surface ablation, intrastromal ablation, conductive keratoplasty (CK), laser thermal keratoplasty (LTK), and corneal and/or scleral implants. An improved topology measuring apparatus having an improved field of view and other attributes is disclosed.

    摘要: In an inventive method for mapping the topography of an eye, elevation measurements of the eye are collected using a slit beam diffuse reflection system, such as an ORBSCAN™ device. An approximating b-spline surface is then fitted to the elevation measurements. Slope measurements of the eye are collected using a Placido-based reflective system, but the slope measurements are referenced to points on the b-spline surface, rather than to points approximated using the conventional constant curvature method, so the measurements have substantially improved accuracy. The elevation and slope measurements are then blended using weighted least squares fitting techniques. A new b-spline surface is fitted to the blended measurements, with the new surface having substantially improved accuracy in depicting the actual topography of the eye as a result of the elevation-improved accuracy of the slope measurements.

    摘要: An apparatus for analyzing a subject's cornea includes a frame having first and second ends, a single curvature (i.e. non-planar and non-axisymmetrical) screen associated with the first end of the frame, the non-planar and non-axisymmetrical screen having an opaque covering which is interrupted along its surface to form a pattern. A light source is disposed to cast the pattern placed on the screen onto the subject's cornea, thus causing a pattern to reflect therefrom. A light detector (e.g. a camera, CCD, or human eye) is disposed to sense the pattern reflected from the subject's cornea. The improved Placido plate is easier to manufacture. The design allows for incorporation of extremely complex pattern shapes, while its shape helps to maintain focus of the image.

    摘要: A method to interactively convert a source language video/audio stream into one or more target languages in high definition video format using a computer. The spoken words in the converted language are synchronized with synthesized movements of a rendered mouth. Original audio and video streams from pre-recorded or live sermons are synthesized into another language with the original emotional and tonal characteristics. The original sermon could be in any language and be translated into any other language. The mouth and jaw are digitally rendered with viseme and phoneme morphing targets that are pre-generated for lip synching with the synthesized target language audio. Each video image frame has the simulated lips and jaw inserted over the original. The new audio and video image then encoded and uploaded for internee viewing or recording to a storage medium.

    摘要: 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.

    摘要: A compact ocular wavefront system with a long working distance is disclosed for use in reducing the overall optical path length for an ocular wavefront system while providing performance similar to that of a traditional system. The system incorporates a compact three-lens subsystem to relay the wavefront from the eye's pupil to a wavefront sensor. The wavefront sensor is placed in close proximity to a digital camera's sensor array. The combination of the compact relay system and the location of the wavefront sensor allows the total track of a traditional ocular wavefront system to be reduced significantly.
