1. A method of treating a crystalline lens of an eye with a laser, the method comprising:

  • selecting a surgical region of the lens; and

    forming an incision in the surgical region on a layer-by-layer basis by scanning a laser beam with an XY scanner of a laser delivery optics along a curved focal plane of the laser delivery optics to form a line of bubbles in each layer without adjusting a Z scanner of the laser delivery optics at a scanning rate of the XY scanner, wherein;

    an orientation of a portion of the incisions is one of an orientation intersecting fibers of the lens and an orientation non-transverse to an axis of the eye; and

    the incision has a spatial extent in a Z direction in the range of 0.5-10 mm, and in an X-Y plane in the range of 2-10 mm.
