  • Patent number: 10555687
    Abstract: Described herein is an apparatus and method for generating a pain score for a patient. The method includes the steps of generating a PLR response signature for each drug of a plurality of drugs and further initiating a light stimulus to the patient, and measuring a corresponding PLR response. The method includes initiating a neuro-stimulus to the patient, the neuro-stimulus being initiated over a set of frequencies, each frequency being associated with a unique intensity, and stimulating a unique nerve fiber type of the patient, and measuring a PRD response of the patient for the initiated neuro-stimulus. Further, the method includes determining, for each nerve fiber type, a threshold response based on the measured PRD, determining a weight for each threshold response based on the PLR response, and combining the determined weight for each threshold response to obtain a pain score for the patient.

  • Patent number: 10463249
    Abstract: An eye movement-based methodology and assessment tool may be used to quantify many aspects of human dynamic visual processing using a relatively simple and short oculomotor task, noninvasive video-based eye tracking, and validated oculometric analysis techniques. By examining the eye movement responses to a task including a radially-organized appropriately randomized sequence of Rashbass-like step-ramp pursuit-tracking trials, distinct performance measurements may be generated that may be associated with, for example, pursuit initiation (e.g., latency and open-loop pursuit acceleration), steady-state tracking (e.g., gain, catch-up saccade amplitude, and the proportion of the steady-state response consisting of smooth movement), direction tuning (e.g., oblique effect amplitude, horizontal-vertical asymmetry, and direction noise), and speed tuning (e.g., speed responsiveness and noise). This quantitative approach may provide fast and results (e.g.

  • Patent number: 9649027
    Abstract: A device for determining biometric variables of the eye, as are incorporated in the calculation of intraocular lenses including a multi-point keratometer and an OCT arrangement. The keratometer measurement points are illuminated telecentrically and detected telecentrically and the OCT arrangement is designed as a laterally scanning swept-source system with a detection region detecting the whole eye over the whole axial length thereof. The multi-point keratometer ensures that a sufficient number of keratometer points are available for measuring the corneal surface. By contrast, telecentricity ensures that the positioning inadequacies of the measuring instrument in relation to the eye to be measured do not lead to a local mismatch of the reflection points. The swept-source OCT scan detects the whole eye over the length thereof so that both anterior chamber structures and retina structures can be detected and a consistent whole eye image can be realized.

    Abstract: Systems and methods for providing enhanced image quality across a wide and extended range of foci encompass vision treatment techniques and ophthalmic lenses such as contact lenses and intraocular lenses (IOLs). Exemplary IOL optics can include a circular surface structure which acts as a diffractive or phase shifting profile. In some cases, a single ring IOL includes an anterior face and a posterior face, where a profile can be imposed on the anterior or posterior surface or face. The profile can have an inner portion such as a microstructure or central echelette, and an outer portion. Between the inner portion and the outer portion, there may be a transition zone that connects the inner and outer portions.

  • Patent number: 9320427
    Abstract: A method and apparatus are disclosed for integrating optical coherence tomography (OCT) and very high frequency ultrasound (VHFU) imaging systems. An OCT probe and reference arm are mounted along with an ultrasound probe on a carriage capable of rotational, linear, and/or arcuate motion. The probe carriage may be immersed in water or other suitable medium. The OCT and VHFU probes move about the cornea surface such that the probe axes are substantially perpendicular relative to the cornea surface throughout a scan. The probes are able to be scanned in an arcuate path across the entire cornea surface. The method and apparatus disclosed are also directed towards providing a positioning mechanism and scan head comprising an arcuate guide track wherein only an OCT probe is mounted on the probe carriage. This embodiment allows the OCT probe beam to remain substantially perpendicular to the cornea and lens surfaces.
