A system and method are provided for fragmenting a crystalline lens, to facilitate its removal from the lens bag during an ophthalmic laser surgery. First, a predetermined pattern is used to make Laser Induced Optical Breakdown (LIOB) cuts that section the lens into asymmetrical, operational segments. At least one operational segment is then selected and softened with a plurality of compact LIOB cuts. Once softened, the selected segment is aspirated. The remaining operational segments are then subsequently removed. During a procedure, an imaging unit can monitor movements of the lens bag to ensure proper placement of the LIOB cuts on the lens.

A system and method for creating a line recognition template that replicates an object is provided for use as a control reference during ophthalmic surgery on the object. Creation of the template first requires aligning a plurality of reference points along a central 'z' axis, with anatomically measured lengths (&#x394;'z') between adjacent reference points. Axially-symmetric surfaces can then be traced between selected, adjacent, reference points to create the template. For the present invention, the location of reference points, and the tracing of axially-symmetric surfaces, are based on a cross sectional image of the object for surgery. Preferably, the cross sectional image is obtained using Optical Coherence Tomography (OCT) techniques.
