摘要： A system includes a controller with at least one processor and at least one non-transitory, tangible memory on which instructions are recorded for executing a method for obtaining a profile of a lens capsule of an eye. The profile is represented by respective central surfaces and respective equatorial surfaces separated at respective transition points. The controller is configured to obtain imaging data for a portion of the lens capsule visible through a pupil of the eye. The imaging data is transformed to an adjusted frame of reference and fitted to the respective central surfaces in a predefined central region of the lens capsule. The profile is obtained based on a set of fitting parameters for the respective central and equatorial surfaces. The respective central surfaces and respective equatorial surfaces may be represented as elliptical cones and skewed parabolas, respectively.

摘要： An ophthalmic portable laser slit lamp for ophthalmic examination and a method of eye inspection. The device comprises a portable housing containing an electronic timer circuit, a rechargeable battery, a laser module containing a laser emitting diode, a fixed focusing lens that sets the appropriate focal distance for the examination method and a line generator lens acting as a slit aperture. The laser beam aimed to the eye of the patient illuminates the eye with a very thin straight laser line at a fixed focal distance. The device also comprises a safety timer circuit that protects the patients eye against irradiation overload. The method of the invention allows the surgeon to detect surgical eye disorders at the operating room and helps to carry out a correct diagnosis in a much more precise and effective way than any light or laser spot device.

摘要： The present disclosure relates to calibration, customization, and improved user experiences for smart or bionic lenses that are worn by a user. The calibration techniques include detecting and correcting distortion of a display of the bionic lenses, as well as distortion due to characteristics of the lens or eyes of the user. The customization techniques include utilizing the bionic lenses to detect eye characteristics that can be used to improve insertion of the bionic lenses, track health over time, and provide user alerts. The user experiences include interactive environments and animation techniques that are improved via the bionic lenses.

摘要： An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X, Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.

摘要： To evaluate the accommodation function of an eye in detail, an accommodation function evaluation apparatus includes an accommodative stimulus applying unit, a measurement unit, and an analyzer. The accommodative stimulus applying unit is configured to apply an accommodative stimulus to the eye. The measurement unit is configured to perform optical coherence tomography for a target site in the eye including at least part of the crystalline lens. The analyzer is configured to analyze data obtained by the optical coherence tomography of the eye, to which the accommodative stimulus is being applied, to generate evaluation information related to the accommodation function of the eye.

摘要： Systems and methods are disclosed for assessing the function of parts of one or more sensory fields of a subject. Pupillary responses to at least two clustered ensembles of stimuli presented to predetermined portions of the sensory fields to be tested are measured. Each cluster comprises individual stimuli presented at locations across the sensory field, where the locations are defined on appropriate axes for the tested sensory fields. The method comprises: presenting statistically independent sequences of selected individual stimuli from the two or more clustered stimulus ensembles to a sensory field of a subject, thereby evoking pupillary responses in at least one pupil of the subject; detecting responses of the pupil or pupils evoked by the stimuli using at least one sensor; and processing the detected responses to relate the detected response to the sensory function of each component part of the sensory field. The sensory fields may be, but are not limited to, the visual fields of the two eyes of a subject.

摘要： A surgical microscope for imaging structures of an eye includes: a front optical unit, an illumination device which has an illumination-radiation-emitting illumination source and which illuminates the retina of the eye with an illumination spot via an illumination beam path which extends through the front optical unit, a camera and an adjustable camera optical unit disposed upstream thereof, an imaging beam path which extends through the front optical unit and the camera optical unit, and a control device which controls the camera optical unit and sets the latter in such a way that the retina of the eye in the region of the illumination spot is imaged on the camera. The control device varies a focusing state of the camera optical unit and, as a result thereof, records a plurality of images of the retina in the region of the illumination spot, the images being focused in different depth planes, and establishes a refractive value of the eye from these images.

摘要： An ophthalmological device emits light from a measurement optical system to an eye to be examined and calculates a dimension along the eye axis of a target portion of the eye from interfering light composed of reflected light from the eye and reference light. The measurement optical system includes incidence position changing member that changes the incidence position of light emitted to the eye, and driving unit that drives the incidence position changing member so as to scan at the incidence position of emitted light in a predetermined region of the eye. The predetermined region is a region where a straight line passes through when the straight line radially extended from the cornea apex of the eye is circumferentially moved over a predetermined angle range in the case of the eye is viewed from the front.

摘要： An optical measurement system method for measuring a characteristic of a subject's eye use a probe beam having an infrared wavelength in the infrared spectrum to measure a refraction of the subject's eye at the infrared wavelength; capture at least two different Purkinje images at two different corresponding wavelengths from at least one surface of the lens of the subject's eye; determine from the at least two different Purkinje images a value for at least one parameter of the subject's eye; use the value of the at least one parameter to determine a customized chromatic adjustment factor for the subject's eye; and correct the measured refraction of the subject's eye at the infrared wavelength with the customized chromatic adjustment factor to determine a refraction of the subject's eye at a visible wavelength in the visible spectrum.
