Disclosed are systems and methods for aligning an ophthalmic device with respect to an eye of a patient. In one disclosure, the system may include an ophthalmic device with an on-axis and an off-axis. The system may include an on-axis illuminator that emits light that is reflected by the eye of the patient to form an on-axis reflection having a center. The system may include an on-axis camera pointed along the on-axis. The system may include an off-axis illuminator that emits light that is reflected by the eye to form an off-axis reflection having a center. The system may include an off-axis camera pointed along the off-axis. The ophthalmic device may be operable to be aligned with respect to the eye of the patient when the on-axis is substantially normal to the center of the on-axis reflection and the off-axis is substantially normal to the center of the off-axis reflection.

A refractor (100) includes: an enclosure having a front face containing a first optical window and a back face containing a second optical window aligned with the first optical window along an optical axis of observation; and at least one vision compensating device making it possible to observe along the optical axis of observation. The vision compensating device includes, between the first window and the second window, a first optical element having a spherical power along the optical axis, the spherical power being variable. The enclosure is mounted on an orientable holder (104) that is rotatable relative to a stationary portion (102) about a horizontal axis (H). A method for measuring refraction employing such a refractor is also disclosed.

A system and method for assessing optical corrective needs of a patient. The system includes a computer system including a processor adapted to run at least a refractive software application thereon, an input device in communication with said processor and adapted to receive input from a user, and a displace device in communication with said processor and adapted to display information, and refractive eyewear including electrically adjustable left and right lenses selectively controllable to adjust at least a sphere power of the respective lenses and in communication with the processor. The refractive software application receives input from the input device and the eyewear controller, and selectively adjusts the sphere power of the left and right lenses, controls information displayed on said display device, and stores information regarding the sphere power of the respective left and right lenses.

A system and method for measuring a characteristic of an eye of a subject receive data pertaining to the subject; assign the subject to an assigned age category based on the data pertaining to the subject; adjust a brightness level of a fixation target according to the assigned age category for the subject; provide the fixation target for a subject to view; and objectively measure at least one characteristic of the eye of the subject while the subject views the fixation target at the adjusted brightness level.

System and method for fully automated end-to-end eye screening with automated medical acquisition and analysis. The system includes an eye imaging device, a mechanism that moves the imaging device, a computing platform that guides the movement mechanism, a user interface, and an electronic display device and/or printer to provide the screening, monitoring, and/or diagnosis report.

Systems and methods for improved interferometric imaging are presented. One embodiment is a partial field frequency-domain interferometric imaging system in which a light beam is scanned in two directions across a sample and the light scattered from the object is collected using a spatially resolved detector. The light beam could illuminate a spot, a line or a two-dimensional area on the sample. Additional embodiments with applicability to partial field as well as other types of interferometric systems are also presented.

A device by which the magnification stages of a magnification selector based on Galilean telescope systems can be adjusted by a motor. The magnification selector has a sensor that transmits the currently magnification stage to a control unit; in the control unit, an assignment of the magnification stages present on the magnification selector to a sequence of the magnification stages, organized based on size, is stored. For the user, there are operating elements connected to the control unit for selecting a magnification stage. In order to set the magnification stage selected by the user via the operating elements, the magnification selector has an actuator, which is connected to the control unit to receive appropriate control signals. Although provided in particular for slit lamps and surgical microscopes having eyepieces, the solution can also be applied in other ophthalmological devices or devices from other technical fields.

An apparatus for use in the measurement of the optical density of macular pigment in the human eye, and an apparatus for the use in measuring the lens optical density of a human eye. The apparatus is particularly applicable to flicker photometers, which are used to measure the macular pigment in the human eye.

An ophthalmologic imaging apparatus that includes a first optical system, a first driver, and a first focus controller. The first optical system includes a first focus lens and a diopter correction lens, and guides light from a subject's eye to a first light receiving element. The first focus lens is movable along the optical axis of a first optical path. The diopter correction lens is insertable into and removable from the first optical path. The first driver moves the first focus lens. The first focus controller executes mutually different focus control of the first driver in a removed state in which the first diopter correction lens is removed from the first optical path and in an inserted state in which the diopter correction lens is inserted into the first optical path.

An ophthalmic examination suite including a base support having a base plate, a carriage movable on the base plate, the carriage being laterally movable between a first position and a second position relative to an instrument delivery stand, and a chair coupled to the carriage, the chair being configured to receive a seated patient thereon.
