Abstract:
1. A parametric model-based computer implemented method for customizing an ablative surgical algorithm for use in refractive ophthalmic surgery, comprising: receiving, with a data receiver of a computer, at least two types of pre-perturbation data pertaining to a cornea on which a refractive ophthalmic surgery will be performed, wherein pre-perturbation data is empirical data acquired before a perturbation of said cornea, said perturbation inducing a biomechanical response; receiving, with a data receiver of the computer, at least two types of post-perturbation data pertaining to said cornea, the post-perturbation data being empirical data acquired after a perturbation of said cornea; wherein the post-perturbation data types received are the same as the pre-perturbation data types received; accessing, with a processor of the computer, a parametric model stored in a computer readable medium, the parametric model storing one or more correlations between measured corneal data and post-operative results pertaining to a plurality of corneas on which refractive ophthalmic surgeries were previously performed, such measured data at least being of the same types as the pre-perturbation and post-perturbation data types; predicting, with a processor of the computer, a post-operative result for said cornea using the parametric model, the pre-perturbation data received, and the post-perturbation data received; and selectively updating, with a processor of the computer, an ablative surgical algorithm stored in a computer readable medium, the updating based, at least in part, on the predicted post-operative result, the pre-perturbation data, and the post-perturbation data; wherein the updated surgical algorithm is customized for the cornea on which a refractive ophthalmic surgery will be performed.
