Abstract

Generation of treatment recommendations for topographic-based excimer laser surgical procedures is described that includes generating accurate cylinder compensation and spherical compensation values that are adjusted to compensate for unique characteristics of advanced topographic-based excimer laser surgical systems. Generating treatment recommendations generally includes determining a topographic vector from a topographic corneal map of the eye, determining a posterior astigmatism vector and an anterior astigmatism vector for the eye, and generating an interior astigmatism vector using the topographic vector, the posterior astigmatism vector, the anterior astigmatism vector, and a manifest astigmatism vector. In various embodiments, the cylinder compensation is generated using the interior astigmatism vector and the posterior astigmatism vector, and the spherical compensation is generated using an initial spherical compensation modified by a topographic addback modifier and a cylinder addback modifier.

Description

Technical field [0001] The present invention relates to excimer laser refractive surgery, and more particularly to an intelligent advisory system for assisting physicians perform excimer laser refractive surgery. Background technique [0002] Laser-assisted in situ keratomy (LASIK) has become one of the most widely used forms in the current molecular laser refractive surgery. Typically, the purpose of such surgical techniques is to change the patient's front cornea shape by ablation tissue to precisely changing the shape of the cornea. Since the surface of the cornea and its air-eye interface are the main source of eye refractive power, various corrections can be made to reduce or even eliminate common vision problems, such as myopia (myopia), high view (super Approach) and astigmatism. [0003] For example, in LASIK surgery for myopia, the matrix tissue is removed to make the curvature of the central cornea level, thereby compensating the over-eye of the myopia or long eye axis ...
