Claim 10:
11. A method for performing refractive laser surgery on a cornea of an eye of a patient using a refractive laser surgery system comprising a laser, a processor, and memory media accessible by the processor and storing instructions or sets of instructions executable by the processor, the method comprising:
identifying, by the processor, a surgical parameter;
correcting, by the processor, the surgical parameter based on a nomogram specific for the refractive laser surgery system to provide a nomogram-based corrected surgical parameter, the nomogram based on actual surgical parameters and actual outcome parameters;
storing, by the processor, the surgical parameter and the nomogram-based corrected surgical parameter in the memory media as data for the patient or for one or both eyes of the patient;
storing, by the processor, the nomogram in the memory media;
periodically updating, by the processor, the nomogram based on subsequent actual surgical parameters and subsequent actual outcome parameters;
comparing, by the processor, the surgical parameter and the nomogram-based corrected surgical parameter to generate a graphical representation of the surgical parameter, a target outcome parameter associated with the surgical parameter, or both, and the nomogram-based corrected surgical parameter, to generate a warning based on a comparison of the nomogram-based corrected surgical parameter to the surgical parameter;
calculating, by the processor, an ablation profile or photodisruption profile for the cornea of the eye of the patient using the nomogram-based corrected surgical parameter; and
sending, by the processor, instructions to the refractive laser surgery system to perform the refractive laser surgery on the cornea of the eye of the patient.
