A photodisruptive laser delivery system and method for use in eye surgery. The photo disruptive laser delivered in pulses in the range of <10000 femtoseconds, used to create incisions in eye tissue is delivered by novel means to minimize optical aberrations without the use of a complex system of multiply precisely arranged lenses. This novel means include a scanning design that allows the focusing lens to always remain under normal incidence to the photodisruptive laser beam, negating the need for overly complex aberration correction set up. The focusing lens is configured to move within a surrounding beam to facilitate two dimensional controls over the treatment space. Controlling beam divergence prior to focusing allows for 3D incisions. The system and methods of use accomplish precise treatment without the need to contact the patient and can be integrated into standard surgical microscopes to improve operational efficiency and hospital workflow.
