A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatmen
A system and method for inserting an intraocular lens in a patient's eye includes a light source for generating a light beam, a scanner for deflecting the light beam to form an enclosed treatment pattern that includes a registration feature, and a delivery system for delivering the enclosed treatment pattern to target tissue in the patient's eye to form an enclosed incision therein having the registration feature. An intraocular lens is placed within the enclosed incision, wherein the intraocular lens has a registration feature that engages with the registration feature of the enclosed incision. Alternately, the scanner can make a separate registration incision for a post that is connected to the intraocular lens via a strut member.

1. A system for surgery on a tissue of a patient's eye, comprising: a. an imaging system for generating image data of one or more structures of the eye;b. a light source for producing a laser beam;c. one or more scanning elements for directing a focal point of a laser beam produced by the light sour
1. A system for surgery on a tissue of a patient's eye, comprising: a. an imaging system for generating image data of one or more structures of the eye;b. a light source for producing a laser beam;c. one or more scanning elements for directing a focal point of a laser beam produced by the light source to various portions of a lens capsule of the eye; andd. a controller operatively coupled to the imaging assembly, the light source and the one or more scanning elements, wherein the controller is programmed to operate the imaging system so as to acquire image data of the one or more structures of the eye, and operate the one or more scanning elements to guide a laser beam produced by the light source based at least in part on the image data to create a capsulotomy and at least one intraocular lens registration feature within the lens capsule of the eye, wherein, taken together, the capsulotomy and the at least one registration feature has rotational asymmetry. 2. The system of claim 1, wherein the at least one registration feature is capable of mating with a complimentary feature of an intraocular lens to orient the intraocular lens. 3. The system of claim 1, wherein the capsulotomy comprises the at least one lens registration feature. 4. The system of claim 3, wherein the at least one lens registration feature comprises an asymmetric shape of the capsular incision. 5. The system of claim 1, wherein the at least one registration feature comprises a feature that is continguous with at least a portion of the capsulotomy. 6. The system of claim 5, wherein the feature comprises a notch or protrusion adjacent a portion of the capsulotomy. 7. The system of claim 1, wherein the light source is a pulsed laser. 8. The system of claim 1, wherein the laser beam has a pulse width of between about 100 femtoseconds and about 10,000 femtoseconds. 9. The system of claim 1, wherein the light source produces a laser beam having a wavelength between about 1,010 nanometers and about 1,100 nanometers. 10. The system of claim 1, wherein the various portions of the lens capsule of the patient's eye are selected from the group consisting of an anterior capsular portion and a posterior capsular portion. 11. The system of claim 1, wherein the one or more structures of the eye are selected from the group consisting of: a cornea, an iris, a lens capsule, and a crystalline lens. 12. The system of claim 1, wherein the image data is selected from the group consisting of: position information, shape information, and size information of the one or more structures of the eye. 13. The system of claim 1, wherein the imaging system comprises a component selected from the group consisting of: an optical coherence tomography system, a Purkinje imaging system, a Scheimpflug imaging system, and a camera. 14. The system of claim 1, wherein the controller is programmed to create the capsulotomy to have a shape selected from the group consisting of: a substantially circular shape, a substantially elliptical shape, and a partially circular shape having a noncircular portion. 15. The system of claim 1, wherein the controller is programmed to create the respective capsulotomy and intraocular lens registration feature by creating one or more incisions with the laser beam. 16. The system of claim 1, wherein the controller is programmed to create at least a portion of the one or more incisions using a continuous pattern. 17. The system of claim 1, wherein the controller is programmed to create at least a portion of the one or more incisions using a discontinuous pattern. 18. The system of claim 1, wherein the controller is programmed to receive user input data and to thereafter automatically operate the one or more scanning elements based at least in part on the received user input data.
