| 20090015789 | CORRECTION OF PRESBYOPIA USING ADAPTIVE OPTICS AND ASSOCIATED METHODS - Devices, systems, and methods measure, diagnose, and/or treat one or both eyes of a patient. Adaptive optics systems (such as those having a deformable mirror) may be configured to an aspherical or multi-spherical presbyopia-mitigating prescriptive shape to allow objective and/or subjective measurements of a candidate prescription. A plurality of viewing distances allow subjective and/or objective evaluations of performance using a light spot or a test viewing image. Measurements of aberrations at selected viewing conditions (including distances and/or brightness) with correlating pupil sizes may also be provided. | 01-15-2009 |

| 20090161070 | APPARATUS AND METHOD FOR DETERMINING OBJECTIVE REFRACTION USING WAVEFRONT SENSING - An apparatus for determining the objective refraction of a patient's eye includes a transparent window and a wavefront measurement device that determines aberrations in a return beam from the patient's eye after the beam passes through a corrective test lens in the apparatus. The wavefront measurement device outputs an instant display representative of the quality of vision afforded the patient through the test lens. The display can be a representation of a Snellen chart, convoluted with the optical characteristics of the patient's vision, an overall quality of vision scale or the optical contrast function, all based on the wavefront measurements of the patient's eye. The examiner may use the display information to conduct a refraction examination and other vision tests without the subjective response from the patient. | 06-25-2009 |

| 20110228225 | METHODS AND DEVICES FOR REFRACTIVE CORRECTION OF EYES - Methods and devices are provided to obtain refractive correction with superior visual acuity (e.g., 20/10) by achieving an astigmatism-free customized refractive correction. The astigmatism-free customized refractive correction involves obtaining an objective and precise measurement of cylindrical power in a resolution between 0.01 D and 0.10 D in an eye using an objective aberrometer, reliably relating the cylindrical axis obtained from the objective aberrometer to that in a phoroptor, determining an optimized focus error of an eye through subjective refraction with a phoroptor, generating a customized refraction by combining the objective measured cylindrical power, the objective measured cylindrical axis, and the subjectively measured focus power, fabricating a custom lens with a tolerance finer than 0.09 D based on the generated customized refraction, and delivering an ophthalmic lens that can provide an astigmatism-free refractive correction for an eye. | 09-22-2011 |
| 20120008094 | Electro-Active Opthalmic Lens Having An Optical Power Blending Region - A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame. | 01-12-2012 |
| 20130135586 | Refraction System for Facilitating Contact Lens Fitting - The present invention contemplates a refraction system facilitating for contact lens fitting via measuring the patient's refraction on the corneal plane and via introducing a conjugated plane of the corneal plane for insertion of a contact lens simulator or phase plate. The present invention also contemplates a refraction system to integrate the objective and subjective measurement into a single instrument. The present invention further contemplates a refraction system with open-field and binocular viewing to overcome instrument myopia and to measure accommodation. The present invention also further contemplates a refraction system employing a pair of optical trombones to eliminate the need of flipping plurality sets of trial lenses for defocus corrections. The present invention even further contemplates a multiple vergence acuity chart to facilitate patient's judgment of best corrected visual acuity. The present invention is thus aimed to provide a refraction system that overcomes the identified issues with the commonly used auto-refractor and phoropter and that enables effective use of contact lens simulators or phase plates to facilitate fitting of multifocal contact lenses for presbyopia correction. | 05-30-2013 |
