There is provided a system, apparatus and methods for developing laser systems that can create a precise predetermined capsulotomy. The systems, apparatus and methods further provide laser systems that reduce the patient-to-patient variability and doctor-to-doctor variability associated with hand held apparatus for performing capsulorhexis and capsulotomies. There is further provided a precise predetermined shot pattern and shaped capsulotomy that is based at least in part on the shape of an IOL and in particular an accommodating IOL.

1. A system for reducing eye to eye and surgeon to surgeon variability in performing procedures to create cuts in the capsule of the crystalline lens of the eye, the system comprising: a. a therapeutic laser for producing a therapeutic laser beam;b. an optical path for directing the therapeutic laser beam from the therapeutic laser to the lens of the eye; and,c. a control system for at least directing the therapeutic laser beam in a predetermined non-geometric shaped shot pattern on a portion of the anterior capsule of the lens of the eye to create a precise predetermined non-geometric shaped capsulotomy, wherein the predetermined shot pattern comprises an essentially straight section. 2. The system of claim 1, wherein the predetermined shot pattern comprises a second essentially straight section. 3. The system of claim 2, wherein the predetermined shot pattern comprises a first curved section and a second curved section. 4. The system of claim 3 wherein: the first essentially straight section is connected to the first and second curved sections. 5. The system of claim 1 comprising a means for determining the apex of the lens of the eye. 6. A system for reducing eye to eye and surgeon to surgeon variability in performing procedures to create cuts in the capsule of the crystalline lens of the eye, the system comprising: a. a therapeutic laser for producing a therapeutic laser beam;b. an optical path for directing the therapeutic laser beam from the therapeutic laser to the lens of the eye;c. a control system for at least directing the therapeutic laser beam in a predetermined non-geometric shaped shot pattern on a portion of the anterior capsule of the lens of the eye to create a precise predetermined non-geometric shaped capsulotomy; and,d. the shot pattern shape being based at least in part on the shape of an IOL, wherein the predetermined shot pattern comprises an essentially straight section. 7. The system of claim 6, wherein the predetermined shot pattern comprises a second essentially straight section. 8. The system of claim 7, wherein the predetermined shot pattern comprises a first curved section and a second curved section. 9. The system of claim 8, wherein: the essentially straight section is connected to the first and second curved sections. 10. The system of claim 6 comprising a means for determining the apex of the lens of the eye. 11. The system of claim 6, wherein the IOL is an FDA approved accommodating IOL. 12. The system of claim 6, wherein the IOL is an FDA approved IOL for near, intermediate and distance vision. 13. The system of claim 6, wherein the IOL is an FDA approved IOL that reduces or eliminates the need for spectacles. 14. A system for reducing eye to eye and surgeon to surgeon variability in performing procedures to create cuts in the capsule of the crystalline lens of the eye, the system comprising: a. a therapeutic laser for producing a therapeutic laser beam;b. an optical path for directing the therapeutic laser beam from the therapeutic laser to the lens of the eye;c. a control system for at least directing the therapeutic laser beam in a predetermined non-geometric shaped shot pattern on a portion of the anterior capsule of the lens of the eye to create a precise predetermined non-geometric shaped capsulotomy;d. the shot pattern shape being based at least in part on the shape of an IOL, the IOL having at least one hinge; and,e. the shot pattern essentially following the shape of the IOL, wherein the shot pattern is positioned on the lens of the eye so that the capsulotomy is in part position outside of the hinge. 15. A system for reducing eye to eye and surgeon to surgeon variability in performing procedures to create cuts in the capsule of the crystalline lens of the eye, the system comprising: a. a therapeutic laser for producing a therapeutic laser beam;b. an optical path for directing a therapeutic laser beam from the therapeutic laser to the lens of the eye;c. a control system for at least directing the therapeutic laser beam in a shot pattern on a portion of the anterior capsule of the lens of the eye to create a cut in the capsule;d. the shot pattern having an X, Y and Z direction component;e. the delivery of the shots in the shot pattern relative to the X, Y and Z directional components being delivered in a jigsaw cut, having a Z direction sweep; and,f. wherein the Z direction sweep is of a magnitude that it substantially reduces the number of missed cuts which reduces eye to eye and surgeon to surgeon variability. 16. A method for making a laser device for creating a precise predetermined capsulotomy, said method comprising: a. obtaining a laser device having a therapeutic laser;b. analyzing an IOL to obtain information about the IOL;c. developing a non-geometric shaped shot pattern for the delivery of the therapeutic laser to the capsule of the crystalline lens of the eye;d. said development being based at least in part upon the information obtained from said analysis; and,e. providing the non-geometric shot pattern to said laser device, wherein the non-geometric shaped shot pattern comprises an essentially straight section. 17. The method of claim 16 wherein the IOL is an FDA approved accommodating IOL. 18. The method of claim 16 wherein the IOL is an FDA approved IOL for near, intermediate and distance vision. 19. The method of claim 16 wherein the IOL is an FDA approved IOL that reduces or eliminates the need for spectacles. 20. The method of claim 16, wherein the predetermined shot pattern comprises a second essentially straight section. 21. The method of claim 20, wherein the predetermined shot pattern comprises a first curved section and a second curved section. 22. The method of claim 21, wherein: the essentially straight section is connected to the first and second curved sections.
