System and method for making incisions in eye tissue at different depths. The system and method focuses light, possibly in a pattern, at various focal points which are at various depths within the eye tissue. A segmented lens can be used to create multiple focal points simultaneously. Optimal incisions can be achieved by sequentially or simultaneously focusing lights at different depths, creating an expanded column of plasma, and creating a beam with an elongated waist.

1. A laser surgical system for making incisions in ocular tissue during a cataract surgical procedure, the system comprising: a laser system comprising a scanning assembly, a laser operable to generate a laser beam configured to incise ocular tissue, and an imaging device; anda control system operably coupled to the laser system and configured to: operate the imaging device to generate image data for ocular tissue of a patient's eye, the image data including lens interior image data for an interior portion of the lens of the patient's eye;process the image data to determine an anterior capsulotomy scanning pattern for scanning a focal zone of the laser beam for performing an anterior capsulotomy; andoperate the laser and the scanning assembly to scan the focal zone of the laser beam in the anterior capsulotomy scanning pattern to perform the anterior capsulotomy, wherein positioning of the focal zone is guided by the control system based on the image data. 2. The system of claim 1, wherein the laser beam has a wavelength between 800 nm and 1,100 nm. 3. The system of claim 1, wherein the laser beam comprises pulses having pulse energy between 1.0 micro joules and 1,000 micro joules. 4. The system of claim 3, wherein the laser beam comprises pulses having pulse energy between 1.0 micro joules and 30 micro joules. 5. The system of claim 1, wherein the laser beam comprises pulses having a pulse duration between about 100 femtoseconds and about 10 picoseconds. 6. The system of claim 1, wherein the laser beam comprises pulses having a repetition rate between 1 kHz and about 200 kHz. 7. The system of claim 1, wherein the anterior capsulotomy scanning pattern is configured to scan the focal zone to different depths, and wherein the focal zone is first scanned at a maximum depth and then scanned to sequentially shallower depths. 8. The system of claim 1, wherein the control system is configured to scan the focal zone of the laser beam to segment the lens into discrete fragments. 9. The system of claim 8, wherein the discrete fragments are sized to be removable through a lumen of an ophthalmic aspiration probe. 10. The system of claim 8, wherein the control system is configured to control the laser and the scanning assembly to segment the lens into the discrete fragments by scanning the focal zone in one or more lens fragmentation scanning patterns. 11. The system of claim 10, wherein the one or more lens fragmentation scanning patterns include at least one of a linear pattern, a planar pattern, a radial pattern, a circular pattern, a spiral pattern, a curvilinear pattern, or two or more overlapping line segments. 12. The system of claim 10, wherein: scanning the focal zone in the one or more lens fragmentation scanning patterns comprises sequentially applying laser pulses to different depths within the lens; andthe laser pulses are first applied at a maximum depth within the lens and then applied to sequentially shallower depths within the lens. 13. The system of claim 1, wherein: the scanning assembly comprises a z-axis scanning device and a transverse scanning device, the z-axis device being operable to change the location of the focal zone of the laser beam parallel to the direction of propagation of the laser beam, the transverse scanning device being operable to scan the location of the focal zone transverse to the direction of propagation of the laser beam; andthe scanning assembly is configured such that the laser beam is acted upon by the z-axis scanning device before being acted upon by the transverse scanning device. 14. The system of claim 13, wherein: the z-axis scanning device comprises one or more movable lenses; andthe transverse scanning device comprises one or more controllable scanning elements. 15. The system of claim 1, wherein the control system is configured to: process the image data to determine one or more axial locations of the anterior capsule of the lens; anddetermine the anterior capsulotomy scanning pattern based on the one or more anterior capsule axial locations. 16. The system of claim 15, wherein the control system is configured to determine a posterior cutting boundary for the anterior capsulotomy scanning pattern based on the one or more anterior capsule axial locations. 17. The system of claim 16, wherein the control system is configured to determine an anterior cutting boundary for the anterior capsulotomy scanning pattern based on the one or more anterior capsule axial locations. 18. The system of claim 1, wherein the control system configures the anterior capsulotomy scanning pattern based in part on an input from a user interface. 19. The system of claim 1, wherein control system controls one or more parameters of the laser beam based on an input from a user interface. 20. The system of claim 19, wherein the one or more laser beam parameters are selected from the group consisting of pulse energy, pulse repetition rate, pulse duration, and wavelength.
