Abstract: In certain embodiments, an ophthalmic laser surgical system for treating a floater in an eye includes a scanning laser ophthalmoscopy (SLO) device, a treatment laser device, and an xy-scanner. The SLO device directs an SLO beam towards the retina of the eye, generates an image that includes the floater shadow from the SLO beam reflected from the eye, determines the xy-location of the floater shadow, and determines the z-location of the floater relative to the retina using the confocal filter. The treatment laser device receives the z-location of the floater from the SLO device, and directs a laser beam towards the z-location. The xy-scanner receives the SLO beam from the SLO device and directs the SLO beam towards the xy-location of the floater shadow. The xy-scanner also receives the laser beam from the treatment laser device and directs the laser beam towards the xy-location of the floater shadow.

Abstract: In certain embodiments, an ophthalmic laser surgical system for treating a floater in an eye comprises a scanning laser ophthalmoscope (SLO) device that: generates an SLO image of a floater shadow cast by the floater onto a retina of the eye, and provides an xy-location of the floater shadow, where the xy-location is related to the xy-scanner. An interferometer device provides a z-location of the floater, where the z-location is relative to the retina. A laser device generates a laser beam and includes a z-focusing component that focuses a focal point of the laser beam onto the z-location of the floater. An xy-scanner directs an SLO beam from the SLO device along an SLO beam path towards the xy-location of the floater shadow, and directs the laser beam from the laser device along the SLO beam path towards the xy-location of the floater shadow.

Abstract: Particular embodiments disclosed herein include projecting an orientation grid into an eye of a patient. A computer system captures one or more images of a retina of an eye of the patient, such as using an SLO, while projecting the orientation grid into the eye of the patient. A fixation grid may also be displayed with the patient being instructed to fixate on the fixation target. The computer system superimposes the orientation grid onto the one or more images to obtain one or more output images. The one or more output images are displayed to at least one of a surgeon and the patient. The surgeon and/or patient may review the output images and communicate the location of floaters using coordinates of the orientation grid.

Abstract: Particular embodiments disclosed herein provide an apparatus for performing optometric measurements includes an optical coherence tomography (OCT) imaging system configured to output scanned parallel laser beams across a patient's eye. A line in the OCT image is identified, the line representing a retina of the patient's eye. A shape of the line is then used by the refractive error calculator to measure refractive error of the patient's eye. The height of the line due to curvature indicates degree of myopia or hyperopia. More complex curvature of the line corresponds to higher order aberrations. OCT images for a plurality of section planes may be used to calculate a wavefront elevation map.

Abstract: Particular embodiments disclosed herein provide a system for treating vitreous floaters. Light from a first laser (e.g., laser diode) is focused at a plurality of points within a vitreous of a patient's eye using a scanner while measuring reflected light from the plurality of points. The reflected light (e.g., images) are evaluated to identify a portion of the plurality of points corresponding to one or more vitreous floaters. Second light from a second laser (e.g., pulsed laser) is focused at the portion of the plurality of points using the scanner in order to disintegrate the one or more vitreous floaters.

Abstract: Particular embodiments disclosed herein provide a method for training a machine learning model to estimate the clinical significance of floaters in a patient's eye. One or more images, such as SLO images or en face retinal OCT images, are evaluated to identify shaded regions corresponding to floaters. The shaded regions are measured and the measurements processed using a machine learning model to obtain an estimated significance. The machine learning model is then updated according to a comparison of the estimated significance to a human-assigned clinical significance. The machine learning model may additionally or alternatively be updated by evaluating the estimated category with respect to visibility threshold data, such as one or more visibility threshold surfaces defined with respect to two or more variables.

Abstract: In certain embodiments, an ophthalmic laser surgical system for treating a target tissue in an eye includes a target detection system and a laser device. The target tissue has an optical breakdown threshold. The target detection system directs detection beams along a detection beam path towards the target tissue in a vitreous of the eye, and determines a location of the target tissue within the vitreous. The laser device includes a femtosecond laser that generates subthreshold laser pulses that have a pulse energy below the optical breakdown threshold of the tissue. The laser device directs a laser beam comprising the subthreshold laser pulses along a laser beam path towards the target tissue.

Abstract: In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes a laser device, imaging system, and computer. The laser device directs the focus of a laser beam towards an intended location (x0, y0, z0) of the target to yield a cavitation bubble in the vitreous. The imaging system directs imaging beams towards the target, receives the imaging beams reflected from the eye, generates an image of the cavitation bubble from the reflected imaging beams, and measures an actual location (x, y, z) of the cavitation bubble according to the image. The computer determines an error vector that describes an error between the intended location and the actual location, determines a correction vector to compensate for the error, and instructs the laser device to use the correction vector to direct the laser beam towards the target to treat the target.
