摘要:
A method for to calculation of actual astigmatism correction and nomographs for corneal laser treatment includes performing a post-operative measurement of the cornea of a patient to determine actual astigmatism coefficients. The actual astigmatism coefficients are compared against the expected astigmatism coefficients to generate a nomograph value or a nomograph curve over a sample population. The nomograph is used to calibrate subsequent laser treatments for improved accuracy of clinical results.
