Abstract
A system and method are provided for fragmenting a crystalline lens inside an operational volume in the lens. A reference axis that is based on the crystalline lens is established, and various pluralities of parallel planes are defined relative to the reference axis. A pulsed laser beam is then used to cut tissue in selected planes, to thereby fragment the lens by performing Laser Induced Optical Breakdown (LIOB) on the tissue. In accordance with the present invention each plurality of parallel planes is characterized by a particular inclination angle “φ” relative to the reference axis, a particular azimuthal angle “θ” relative to the reference axis, and an intersection angle “ψ” relative to each other.
