OG exemplary drawing
1. An ophthalmic laser surgical system, comprising:
a pulsed laser source configured to generate a pulsed laser beam;
optics configured to direct the laser beam towards a target region in a lens of an eye, wherein the lens includes elongated fibers;
a processor configured to:
control the optics to form a laser pattern of a regular array of cells in the target region by creating layers of photodisrupted bubbles to generate cell boundaries and
control the optics to direct pulsed laser source to generate the laser pattern with a spot separation with a higher spot density and/or a higher laser pulse energy to form the cell boundaries that are perpendicular to the elongated fibers, as compared to when the cell boundaries are located parallel to the elongated fibers.
