摘要
A system and method for performing refractive surgery in an eye requires creating a plurality of cuts in the stroma or the lens that are randomly positioned relative to a reference axis. The geometry for each cut is unique and includes a start point in the stroma that is identified by a distance “r” from the axis, and an azimuthal angle “θ” that is measured around the axis. A computer provides concerted control for a laser unit and an optical scanner to randomly vary the start point for each cut, to create a pattern of cuts that will implement the desired refractive surgery, yet be visually illusive.
