MINIMIZING THE SIDE-EFFECTS OF REFRACTIVE CORRECTIONS USING STATISTICALLY DETERMINED IRREGULARIITIES IN THE INTRASTROMAL INCISIONS

摘要

A system and method for minimizing adverse visual effects that may be introduced during laser refractive surgery, requires making laser incisions into stromal tissue in a predetermined manner. Specifically, a plurality of irregular incisions are statistically distributed in the stroma in a manner that causes them to be visually elusive, and thereby minimize their adverse visual effects. The incisions must, however, still accomplish their intended surgical purpose of weakening the stroma in a predetermined manner. To do this, each irregular incision has a width of arc length dθm, a length dzi and a characteristic radial distance drn from the visual axis of the eye. Values for dθm, dzi and drn are established using a random number generator.
