In certain embodiments, an ophthalmic surgical system for viewing an eye includes an ophthalmic microscope and a laser device. The ophthalmic microscope receives light reflected or scattered backwards from within the vitreous of the eye in order to provide an image of an object within the vitreous. The ophthalmic microscope includes a slit illumination source (which includes a light source and an optical element), a spectral filter, and oculars. The slit illumination source illuminates the eye with light, where the light source provides the light, and the optical element directs the light into the eye. The spectral filter filters out red spectral components of the light. The oculars receive the light from the eye in order to provide the image of the object. The laser device generates a laser beam to direct towards the object within the eye.

In certain embodiments, an ophthalmic laser system that performs a laser procedure on an eye includes a laser device, an ophthalmic microscope, a y-direction motor, a user interface device, and a controller. The laser device includes a laser delivery head that directs a laser beam towards a target within the eye. The laser beam defines a z-axis, which defines an xy-plane with a y-axis that defines a y-direction. The ophthalmic microscope receives light from within the eye to provide an image of the eye. The user interface device receives instructions from a user. The controller receives an instruction from the user interface device to move the laser delivery head and the ophthalmic microscope in the y-direction, and instructs the y-direction motor to move the laser delivery head and the ophthalmic microscope in the y-direction in response to the instruction.

A reflectometry instrument includes a light source for emitting an illumination beam that illuminates the macula. A portion of the illumination beam is reflected from the macula and forms a detection beam. The detection beam is indicative of macular pigment in the macula. The instrument also includes a first mirror for reflecting the illumination beam toward the macula and for reflecting the detection beam from the macula. The instrument is configured so that the illumination beam and the detection beam remain separated between the macula and the first mirror.

A visual performance examination device includes a display control unit that displays an indicator at each of a plurality of positions in a display screen of a display device; an image data obtaining unit that obtains an image data of eyes of a test subject, which are irradiated with a detection light emitted from a light source; a position calculating unit that, based on the image data, calculates a position data of corneal reflexes of the eyes when each of a plurality of indicators displayed at the positions in the display screen is shown; and an evaluating unit that, based on relative positions of the indicators and relative positions of the corneal reflexes, outputs evaluation data about visual performance of the test subject.

A subjective and objective integrated precise optometry device, and an optometry method are provided. The device has a left eye optical path and a right eye optical path. Each of the single eye optical paths comprises a human eye refraction objective measurement subsystem, a human eye refraction correction subsystem, an eyeball positioning subsystem, and a subjective visual function testing subsystem. The device has functions such as objective measurement for monocular and binocular refraction, continuous subjective optometry, interpupillary distance measurement, and monocular and binocular visual function measurement (comprising, but not limited to, vision and stereopsis), and can implement subjective and objective integrated precise monocular and binocular optometry. Additionally, the device has such functions as rapid measurement and screening of human eye refraction, and preliminary screening of human eye diseases (except for ametropia), and can be used for optometry, ophthalmological clinical triage, population ametropia screening and monitoring, etc.

Systems and methods for allowing a user with no prior training to receive automated vision measurements without assistance of another individual by using subjective inputs from a user, which may be supplemented by a predictive method. The predictive method comprising artificial intelligence, patient data, user inputs, automated inputs from cameras and the like. The system may make use of a specific algorithm, decision tree, set of instructions, programming instructions, and the like, in order to provide vision measurements. The system combines programming instructions executed by a processor, output devices, input controls, and a plurality of corrective lenses to find a patient or user's vision measurements.

An ophthalmological measuring device including an ocular measuring unit including a front face provided with a frame encircling a translucent plate the size and curvature of which are suitable for covering the ocular field of said patient, a device for providing uniform backlighting of the translucent plate, located behind the translucent plate, at least one camera equipped with an objective placed in line with a hole in the translucent plate, one or more point light sources in apertures on the edges of the translucent plate, for illuminating the eyes of the patient, and means for fastening one or more additional ophthalmological measuring devices to the translucent plate.

An ophthalmoscope for examining eyes, includes: a housing; a converting device for converting light into an electrical signal; and an objective, the objective comprising a lens and/or a mirror. The objective has a convexly curved focus area, a convexly curved image surface of an eye being able to be sharply imaged onto the converting device by means of the objective.

An automatic eye test device and an automatic eye test method are disclosed. The automatic eye test device includes an automatic positioning module, an automatic test module and an automatic analysis module. The automatic positioning module is configured to automatically complete positioning of an eye of a person to be tested. The automatic test module is coupled to the positioning module and configured to automatically test the eye of the person to be tested to obtain a test result. The automatic analysis module is coupled to the automatic test module and configured to automatically analyze the test result to provide a personalized test suggestion for the person to be tested.

A refraction device includes a main body, a spherical power lens coupled to the main body, an astigmatic power lens movably coupled to the main body, and a visual display coupled to the main body and oriented toward an optical pathway extending through the spherical power lens and the astigmatic power lens. The visual display is configured to display an image for testing visual acuity.
