Claim:
1. A method for performing ophthalmic laser surgery, the method comprising: determining an expected variation in post-surgical relaxation of ocular tissue along an incision site; providing an automated laser surgery system comprising: operating the automated laser surgery system to selectively ablate ocular tissue to provide an elongated structured incision extending in arcuate fashion across the steep meridian of the cornea, the structured incision being structured to be non-uniform along its length, the non-uniformity being specifically configured to counteract the expected variation in post-surgical relaxation of ocular tissue, and thus to provide an improved corrective effect; wherein operating the automated laser surgery system comprises operating the automated laser surgery system to selectively ablate ocular tissue to provide an elongated structured incision that is non-uniform in at least one of angle of attack relative to a surface of the ocular tissue, profile, and width, said elongated structured incision having a greater width of cut at its end portions than at its central portion, the width being measured transversely to a direction of elongation of the structured incision.
