A laser surgery system to fragment the lens of an eye lens, the system comprising: a pulsed laser (302) adapted to generate a pulsed laser beam; an optical module (310) comprising one or more lenses and one or more reflectors adapted to focus and direct the laser beam towards a target region (301) in the lens tissue; an imaging device (330) adapted to collect light or sound reflected or scattered from the target region (301) in the lens tissue to capture image data; a system control module (320) adapted to generate a laser control signal to control the pulsed laser (302) and generate a beam control signal to control the optical module (310) to adjust the focus and direction of the laser beam in response to the beam control signal; where the system control module (320) is adapted to process the captured image data to determine the positioning of the applied laser pulses; characterized in that the system control module (320) is further adapted to control the optical module to perform a scan with the pulsed laser to form a regular array of cells in a volume of the target region located in the lens by creating bubble layers generated by laser-induced photodisruption to generate cell surfaces and boundaries so that curved layers of bubbles generated by photodisruption are created that adapt to the natural curvature in the target region in the lens of the eye lens, thus fractionating the tissue along surfaces and cell boundaries in granules of fragmented tissue for extraction by aspiration.Un sistema de cirugía láser para fragmentar el tejido del cristalino de un ojo, comprendiendo el sistema: un láser pulsado (302) adaptado para generar un haz de láser pulsado; un módulo óptico (310) que comprende una o más lentes y uno o más reflectores adaptados para enfocar y dirigir el haz de láser hacia una región objetivo (301) en el tejido del cristalino; un dispositivo de formación de imágenes (330) adaptado para recoger luz o sonido reflejados o dispersados desde la región objet
