    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.

    Abstract: A narrow angle illumination light source for an ophthalmic surgical laser system includes multiple light emitting diodes (LEDs), multiple corresponding ball lenses, multiple corresponding upper apertures located between the LEDs and the lenses (optional), and multiple corresponding lower apertures located below the lenses. The light passing through each upper aperture and corresponding lens forms a light cone having a defined divergence angle and cone axis angle; the light cone only illuminates the corneal and sclera of a docked eye without illuminating the patients nose and orbit. The lower apertures may have distinctive shapes to aid video focusing. The multiple LEDs are distributed uniformly in the circle, and may be divided into multiple independently controllable segments which allows directional illumination The LEDs also have controllable brightness to allow images of darker and brighter illuminations to be taken in short succession.

    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.
