A system and method for altering the configuration of a transparent material (e.g. the cornea of an eye) requires identifying local stress distribution patterns inside the material. These patterns are then used to define boundary (interface) surfaces between volumes within the material. In operation, a laser unit performs Laser Induced Optical Breakdown (LIOB) along selected boundary surfaces to disrupt stress distribution patterns between volumes of the material that are separated from each other by the boundary surface. This LIOB allows an externally applied force to thereby alter the configuration of the material.
