High-Order Optical Correction During Corneal Laser Surgery

摘要

Systems and methods related to corneal ablation for treatment of one or more high-order optical aberrations are provided. A method includes providing a defect-correcting prescription, determining an ablation profile to impose the prescription on the cornea, and determining a sequence of laser-energy ablations to impose the ablation profile on the cornea. The prescription comprises a high-order optical correction. The ablation profile includes a first-segment profile and a second-segment profile. The second-segment profile corresponds to at least one high-order optical correction. The ablation sequence includes applying ablations corresponding to the first-segment profile prior to applying ablations corresponding to the second-segment profile.

1. A method for sequencing an ablation of a cornea of an eye to impose a defect-correcting prescription on the eye, the method comprising:
providing the defect-correcting prescription, the prescription comprising a high-order optical correction; determining an ablation profile to impose the prescription on the cornea, the ablation profile comprising a first-segment profile and a second-segment profile, the second-segment profile corresponding to at least one high-order optical correction; and determining a sequence of laser-energy ablations to impose the ablation profile on the cornea, wherein the sequence comprises applying ablations corresponding to the first-segment profile prior to applying ablations corresponding to the second-segment profile.
