    Abstract: A laser surgery system includes a light source, an eye interface device, a scanning assembly, a confocal detection assembly and preferably a confocal bypass assembly. The light source generates an electromagnetic beam. The scanning assembly scans a focal point of the electromagnetic beam to different locations within the eye. An optical path propagates the electromagnetic beam from a light source to the focal point, and also propagates a portion of the electromagnetic beam reflected from the focal point location back along at least a portion of the optical path. The optical path includes an optical element associated with a confocal detection assembly that diverts a portion of the reflected electromagnetic radiation to a sensor. The sensor generates an intensity signal indicative of intensity the electromagnetic beam reflected from the focal point location. The confocal bypass assembly reversibly diverts the electromagnetic beam along a diversion optical path around the optical element.

    Abstract: A laser eye surgery system includes a computer which scans a focused laser beam in a trajectory over a reticle or target and determines beam quality via laser light reflected from the target. The target may have a grid pattern of lines, with the diameter of the focused laser beam determined based on a time interval for the scanned beam to move onto a line of the grid pattern. Methods for measuring beam quality in a laser eye surgery system provide a direct, quantitative quality measurement of the focused laser beam, and may be performed quickly and automatically. Using scanning mirror position information together with signals resulting from laser light reflected from the target, the laser eye surgery system may also be calibrated.

    Abstract: A method of cataract surgery in an eye of a patient includes identifying a feature selected from the group consisting of an axis, a meridian, and a structure of an eye by corneal topography and forming fiducial mark incisions with a laser beam along the axis, meridian or structure in the cornea outside the optical zone of the eye. A laser cataract surgery system a laser source, a topography measurement system, an integrated optical subsystem, and a processor in operable communication with the laser source, corneal topography subsystem and the integrated optical system. The processor includes a tangible non-volatile computer readable medium comprising instructions to determine one of an axis, meridian and structure of an eye of the patient based on the measurements received from topography measurement system, and direct the treatment beam so as to incise radial fiducial mark incisions.
