摘要：
Embodiments generally relate to systems and methods for lenticular laser incisions based on wavefront maps. In an embodiment, a method comprises obtaining a wavefront map of a free eye using wavefront aberrometry to measure a refractive error, obtaining an iris image for the free eye using wavefront aberrometry, determining a free eye cutting profile to cut the cornea based on the wavefront measurement, determining a first translation of the free eye cutting profile based on estimated perturbation of the eye with a docking patient interface, docking the eye to a patient interface of an ultrashort pulsed laser system, obtaining an iris image for the docked eye, determining a second translation of the cutting profile for the docked eye from the free eye, using comparisons between the two iris images, and incising a bottom surface incision in the cornea based on the two translated cutting profiles.
