Abstract: Optical correction methods, devices, and systems reduce optical aberrations or inhibit refractive surgery induced aberrations. Error source control and adjustment or optimization of ablation profiles or other optical data address high order aberrations. A simulation approach identifies and characterizes system factors that can contribute to, or that can be adjusted to inhibit, optical aberrations. Modeling effects of system components facilitates adjustment of the system parameters.

Abstract: Devices, systems and methods for scaling the size and/or position of a marker on a magnified image of an object. In preferred embodiments, the object is an eye that is undergoing laser eye surgery. The eye is viewed through a magnification system or microscope and an image of the eye is presented on a display. One or more markers are present on the image, each identifying a specific target location or landmark on the eye. When a desired magnification setting is selected, the image is scaled accordingly. In addition, one or more of the markers is scaled in size and/or position to reflect the magnification setting. This allows the marker to maintain identification of the target location while reflecting the selected magnification level.

Abstract: Devices, systems, and methods for measuring and determining positions of light energy having wavelengths of less than (as well as equal to or greater than) 200 nm, and are particularly well suited for measuring pulsed light at ultraviolet and other wavelengths using position sensing diode (PSD) technology. An integrator may sum a total charge of a signal from the PSD. Correlations between a distribution of integrated charges among electrodes of the PSD may be non-linear, and may benefit from adjustment for different overall pulse light quantities and/or spot sizes.
