  • Publication number: 20130169930
    Abstract: Exemplary embodiments enable an enhanced direct-viewing optical device to make customized adjustments that accommodate optical aberrations of a current user. In some instances a real-time adjustment of the transformable optical elements is based on known corrective optical parameters associated with a current user. In some implementations a control module may process currently updated wavefront measurements as a basis for determining appropriate real-time adjustment of the transformable optical elements to produce a specified change in optical wavefront at an exit pupil of the direct-viewing device. Possible transformable optical elements include refractive and/or reflective and/or diffractive and/or transmissive characteristics that are adjusted based on current performance viewing factors for a given field of view of the direct-viewing device.

  • Patent number: 8474974
    Abstract: Wavefront measurements of eyes are typically taken when the pupil is in a first configuration in an evaluation context. The results can be represented by a set of basis function coefficients. Prescriptive treatments are often applied in a treatment context, which is different from the evaluation context. Hence, the patient pupil can be in a different, second configuration, during treatment. Systems and methods are provided for determining a transformed set of basis function coefficients, based on a difference between the first and second configurations, which can be used to establish the vision treatment.

  • Patent number: 8444632
    Abstract: A method of performing refractive laser eye surgery on a human eye is provided wherein the ablation pattern is centered along the visual axis, rather than along the line of sight. First, a wavefront, either ocular, corneal or a combination thereof, is generated by a wavefront sensor centered along the line of sight. This measured wavefront is centered on and encompasses a patient's pupil. Then, an analysis pupil is determined which encompasses the measured pupil. The analysis pupil is centered along the visual axis at the point of intersection with the cornea. Consequently, the measured wavefront is reconstructed over the analysis pupil only using data taken over the area covered by the measured pupil. This reconstruction is done through a least squares fit of a series of slopes from the measured wavefront and/or through the transformation of aberration coefficients.

  • Patent number: 8394083
    Abstract: A wavefront sensor is integrated with a surgical microscope for allowing a doctor to make repeated wavefront measurements of a patient's eye while the patient remains on an operating table in the surgical position. The device includes a wavefront sensor optically aligned with a surgical microscope such that their fields of view at least partially overlap. The inclusion of lightweight, compact diffractive optical components in the wavefront sensor allows the integrated device to be supported on a balancing mechanism above a patient's head during a surgical procedure. As a result, the need to reposition the device and/or the patient between measuring optical properties of the eye and performing surgical procedures on the eye is eliminated. Many surgical procedures may be improved or enhanced using the integrated device, including but not limited to cataract surgery, Conductive Keratoplasty, Lasik surgery, and corneal corrective surgery.

  • Patent number: 8393734
    Abstract: A method of screening a pupil of a subject to determine whether the pupil reflex resembles a canonical pupil reflex is disclosed. The method comprises the steps of stimulating the pupil with a stimulus source. The method further includes the steps of using a pupilometer to track the pupil's constriction response over a duration of time, wherein the step of tracking the pupil constriction response begins substantially simultaneously with or immediately subsequent to time 0 and lasts for a period of time y, and using the pupilometer to collect a plurality of data points in which each data point corresponds with a diameter of the pupil at a specific time within the time duration y. The method further includes the step of generating a pupil data profile by compiling the data points and determining whether one or more conditions arc met.

  • Publication number: 20130060241
    Abstract: An apparatus and method for actively compensating for pupil centroid shift includes obtaining a first measurement of a first reference point relative to a predetermined reference frame, wherein the first reference point being associated with a first pupil diameter of a patient. The method further includes obtaining a second measurement of a second reference point relative to the predetermined reference frame, wherein the second reference point is associated with a second pupil diameter of the patient and the second pupil diameter is different from the first pupil diameter. The method still further includes actively determining a relationship between the first measurement and the second measurement and actively generating a correction in response to the relationship, wherein the correction being used by a treatment laser in association with an eye surgery.

  • Patent number: 8388136
    Abstract: Methods and devices measure eye blinks and tear film lipid and aqueous layer thickness before and following ophthalmic formula application onto the ocular surface, especially wherein the ophthalmic formula is an artificial tear. The methods and devices are suitable for dry eye diagnosis. The methods and devices are suitable for use to evaluate ophthalmic formula effects on the tear film and to use such information to diagnose ophthalmic formula treatment of ocular disease conditions such as dry eye in the absence of contact lens wear or post-surgical eye drop treatment and diagnosis. The methods and devices are also suitable for use in the optimization of ophthalmic drug dosage forms and sustained drug release.

  • Patent number: 8382284
    Abstract: A method and system for providing multiple ophthalmic and retinal blood measurements is outlined. By extracting multiple digitized wavelength images and quantitative data within a relatively short time period the method allows for compensation of a patient's eye or head movement, generation of ophthalmic clinical records, and determination of data relating to blood measurements, such as oxygen saturation and hemoglobin, in addition to ocular and other disease determinations. The method provides for multiple analysis and measurements within a single sitting of the patient, with a single simple instrument and without adaptations to the instrument during a patient's eye examination. Beneficially the approach allows for low cost, compact, and even portable implementations offering such analysis and determination outside the current ophthalmic centers providing eased access and earlier diagnosis opportunities.
