An instrument for imaging the eye and performing ophthalmic diagnostic tests is disclosed that obtain images of the structures of the eye using imaging technology such as optical coherence tomography (OCT). To assist with such imaging and/or provide additional diagnostics, the ophthalmic diagnostic instrument may additionally include a display for presenting images to the subject whose eyes and vision are being evaluated. This display system may comprise a MEMS (microelectromechanical system) scanning mirror.

A surgical imaging system, including a first imaging device configured to generate a real-time visual image of a first field of view of a patient, and a second imaging device configured to generate a real-time thermal image of the first field of view. The system also includes a retaining structure, configured to be positioned in proximity to an eye of an operator, and a semitransparent screen configured to be mounted on the structure. The system additionally includes a processor configured to receive the images, and upon receiving an indication from the operator, to present, on the screen, the real-time visual image, or the real-time thermal image or the real-time thermal image overlaid on the real-time visual image, focused to a point in proximity to a near point of the eye while the operator can view, through the screen, a second field of view different from the first field of view.

An image processing apparatus includes a determination unit configured to determine, as a partial region of a multi-channel fundus image including an optic disk area and a macular area of a subject's eye, one of a region of the multi-channel fundus image which includes the macular area and a region of the multi-channel fundus image which includes the optic disk area, and a generation unit configured to generate an image in which a difference in color of the partial region is enhanced, by applying to the partial region image processing based on a decorrelation stretching method.

The present disclosure relates generally to systems and method for testing and determining corrective lens prescription for a patient. In an example embodiment, a system includes a hand-portable first electronic device, a second electronic device with a computerized screen, and a server to conduct a vision test for a person. The vision test includes determining, an axis prescription, a cylinder prescription, and a sphere prescription for each eye of the person. A corrective lens prescription is provided for the person based, at least in part, on the determined axis, cylinder, and sphere prescription for each eye of the person.

An ophthalmologic imaging apparatus which captures a tomographic image of a subject's eye using interference light obtained by combining a return light from the subject's eye irradiated by measurement light and a reference light includes a control unit configured to perform (a) control, when a first imaging mode for capturing the tomographic image of the subject's eye is selected, to display the tomographic image as a first tomographic image of the subject's eye on a display unit and (b) control, when a second imaging mode different from the first imaging mode is selected, to display a second tomographic image of the subject's eye on the display unit, the second tomographic image generated using the tomographic image to increase intensity of the second tomographic image higher than that of the first tomographic image.

An ophthalmologic photographing apparatus includes: a photographing optical system including an optical scanner for scanning an examinee's eye with measurement light and a detector for detecting a coherent state of reflected light of the measurement light from the examinee's eye and reference light, the photographing optical system being configured to capture a tomographic image of the examinee's eye in response to an output signal from the detector; a reference data setting unit for setting a photographing condition of a previously acquired captured image as reference data for a follow-up; an image capture data setting unit for setting the reference data set by the reference data setting unit as image capture data for the follow-up; and a tomographic image acquisition controller for acquiring a tomographic image of the examinee's eye by controlling the photographing optical system based on the reference data set as the image capture data.

In order to take advantage of the real time nature of intra-operative refraction or wavefront aberrometry, and visually make the history of the measurements apparent to a surgeon, a histogram of frequency vs IOL results calculated from an IOL formula is computed and IOL suggestions being accumulated are displayed in a histogram. One embodiment is a means to present to a surgeon a histogram of intra-operative refractions. Another embodiment is to automatically and intra-operatively detect the aphakic phase of a cataract surgery to display a histogram of a recommended IOL power.

Systems and methods are disclosed for evaluating human eye tracking. One method includes receiving data representing the location of and/or information tracked by an individual's eye or eyes before, during, or after the individual performs a task; identifying a temporal phase or a biomechanical phase of the task performed by the individual; identifying a visual cue in the identified temporal phase or biomechanical phase; and scoring the tracking of the individual's eye or eyes by comparing the data to the visual cue.

An ophthalmic surgical system includes an imaging unit configured to generate a fundus image of an eye and a depth imaging system configured to generate a depth-resolved image of the eye. The system further includes a tracking system communicatively coupled to the imaging unit and depth imaging system, the tracking system comprising a processor and memory configured to analyze the fundus image generated by the imaging unit to determine a location of a distal tip of a surgical instrument in the fundus image, analyze the depth-resolved image generated by the depth imaging system to determine a distance between the distal tip of the surgical instrument and a retina of the eye, generate a visual indicator to overlay a portion of the fundus image, the visual indicator indicating the determined distance between the distal tip and the retina, modify the visual indicator to track a change in the location of the distal tip within the fundus image in real-time, and modify the visual indicator to indicate a change in the distance between the distal tip of the surgical instrument and the retina in real-time.

An ophthalmic apparatus obtains naked-eye wavefront aberration data of an examinee's eye measured by an aberration measuring unit, and calculates first corrected wavefront aberration data intended for a prescription with a first correction power based on the naked-eye wavefront aberration data and the first correction power and generates a first evaluation index based on the first corrected wavefront aberration data. The ophthalmic apparatus further calculates second corrected wavefront aberration data intended for a prescription with a second correction power different from the first correction power in at least one of spherical power, astigmatic power, and astigmatic axis angle based on the naked-eye wavefront aberration data and the second correction power, and generates a second evaluation index based on the second corrected wavefront aberration data. The ophthalmic apparatus then displays the first and second evaluation indexes selectively or in parallel on a monitor.
