摘要： An optical measuring instrument 1 is equipped with an optical system 20 to be used for measuring a characteristic of the aqueous humor in the anterior chamber 13 of an eyeball 10 of a measurement subject person and a holding unit 50 which holds the optical system 20 etc. The optical system 20 is equipped with a light emitting system 20A and a photodetecting system 20B. An optical path 28 is set so that light emitted from the light emitting system 20A passes through (traverses) the anterior chamber 13 and is detected by the photodetecting system 20B in a state that the eyeball 10 is turned outward.

摘要： A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced.

摘要： A contact lens for examining an eye under an incident light beam includes a main element having: a planar first entrance face placed perpendicularly to the beam; at least one reflective face; and a spherical exit face having a centre of curvature and an axis of symmetry that is perpendicular to the entrance face and that passes through the centre of curvature, the exit face being intended to be applied to the eye and to focus the beam on a working point in the interior of the eye, a second entrance face placed facing the spherical exit face, along the axis of symmetry; and a central void extending from the planar first entrance face to the second entrance face.

摘要： A non-sliding, non-sutured hands-free contact lens assembly for ophthalmic procedures utilizes a number of microstructures strategically placed on the bottom of either the contact lens or the bottom of a contact lens holder ring. After the contact lens, or the contact lens assembled with the contact lens holder ring, is placed on the cornea of the eye and centered, a surgeon applies downward pressure either on the contact lens itself or on the lens holder ring. This secures the lens assembly to the cornea due to increased friction between the microstructures and the tissues of the eye when the microstructures penetrate through the tear film and, optionally, viscous solution film and into the contact with superficial layer of cornea or other parts of the eye, thus temporarily anchoring the contact lens, or lens holder, to the desired surgical site.

摘要： An ophthalmologic apparatus includes an optical scanner, an interference optical system that splits light from a light source into measurement light and reference light, projects the measurement light onto a subject's eye via the optical scanner, and detects interference light generated from returning light of the measurement light from the subject's eye and the reference light, a controller that controls the optical scanner so as to perform scan by the measurement light in an intersecting direction which intersects a traveling direction of the measurement light, and an analyzer that specifies a scan length based on a detection result of the interference light corresponding to the scan, the detection result being acquired by the interference optical system, the scan length being a length of a scan range in the intersecting direction within a characteristic region in an anterior segment of the subject's eye, and specifies a movement amount of the subject's eye based on a reference value of the characteristic region and the scan length.

摘要： The ophthalmologic apparatus comprises an optical system for acquiring data of a subject's eye optically, an image acquiring unit that acquires a first image of an anterior segment of the subject's eye and a second image of the anterior segment at different timings from each other, a rotational movement amount calculator that calculates a rotational movement amount between a partial image in the second image and a corresponding partial image in the first image, the corresponding partial image corresponding to the partial image, a registration unit that performs registration between the corresponding partial image and the partial image in a rotation direction based on the rotational movement amount, a parallel movement amount calculator that performs a phase only correlation processing on the corresponding partial image and the partial image registered by the registration unit to calculate a parallel movement amount between the corresponding partial image and the partial image, a movement mechanism that moves the subject's eye and the optical system relative to each other, and a controller that controls the movement mechanism based on at least one of the rotational movement amount and the parallel movement amount.

摘要： In accordance with one aspect of the present invention, an optical coherence tomography-based ophthalmic testing center system includes an optical coherence tomography instrument comprising an eyepiece for receiving at least one eye of a user or subject; a light source that outputs light that is directed through the eyepiece into the user's or subject's eye, an interferometer configured to produce optical interference using light reflected from the user's/subject's eye, an optical detector disposed so as to detect said optical interference; and a processing unit coupled to the detector. The ophthalmic testing center system can be configured to perform a multitude of self-administered functional and/or structural ophthalmic tests and output the test data.

摘要： A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

摘要： Single piece ophthalmic inspection devices are provided having a continuous 3-dimensional molded surface preferably made out of plastic. The devices are relatively easier and cheaper to manufacture than existing inspection lenses. The smooth continuous edges are advantages to prevent damage to tissue as well to stop foreign objects accumulating in e.g. the clear regions of the lens. Ergonomic features built into the ophthalmic inspection device provide for superior control of the device on the patient's eye. In addition, textured knurled or grooved surfaces provide desired finger grip and control of the device.
