IRIS REGISTRATION METHOD AND SYSTEM
A method that includes illuminating an eye with light at a first time and a second time and generating a first image of the eye based on the light that illuminates the eye at the first time. The method includes generating a second image of the eye based on the light that illuminates the eye at the second time. The method further includes positioning a laser source relative to the eye, wherein the laser source generates a therapeutic laser beam to be directed to the eye, wherein the first time is just prior to the therapeutic laser beam being directed to the eye and the second time is prior to the first time. The method further includes correcting orientation of the laser source relative to the eye based on a correlation function that is defined for the first and second images of the eye.

Tracking movement of an eye within a tracking range
In certain embodiments, a system for tracking movement of an eye comprises a camera system, a computer system, and an output device. The camera system generates images of the eye. The computer system stores the images and at least one of the images as a reference image. The computer system also tracks movement of the eye within a tracking range by comparing a current image with the reference image, and by determining a movement of the eye from the comparison of the current image and the reference image. The tracking range has one or more alert points. The computer system also determines an orientation of the eye relative to at least one alert point of the tracking range. The output device outputs a range indicator that indicates the orientation of the eye relative to the at least one alert point of the tracking range.
SLO-BASED LASER GUIDANCE FOR TREATING VITREOUS FLOATERS
In certain embodiments, an ophthalmic surgical laser system for imaging and treating an eye floater includes an SLO subsystem, a treatment laser subsystem, a scanner, optical elements, and a computer. The SLO subsystem provides an SLO laser beam with an SLO focal point, and the treatment laser subsystem provides a treatment laser beam with a treatment focal point that spatially coincides with the SLO focal point. The scanner scans the SLO laser beam across a scan region and directs the treatment laser beam to the xy-location of the scan region. The optical elements aim the SLO laser beam and the treatment laser beam at substantially the same point of the scan region. The computer receives an SLO image of the floater, determines an xy-location of the floater, and instructs the treatment laser subsystem to direct the treatment laser beam towards the xy-location and the z-scan location of the floater.
