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.
