Precise targeting of surgical photodisruption

1. A laser surgical system, comprising:

a pulsed laser source, configured to produce a laser beam of laser pulses;

an optics module configured

to receive the laser beam from the pulsed laser source,

to direct the laser beam into a lens of an eye, and

to scan the laser beam in the lens of the eye;

an Optical Coherence Tomography (OCT) imaging device, configured to create an OCT image of the lens of the eye;

a non-OCT imaging device, configured to generate a non-OCT image of the eye; and

a system control module, configured

to register the eye to the laser surgical system based on the non-OCT image, and

to control the optics module directing and scanning the laser beam based on the registering wherein the non-OCT imaging device is configured to generate the non-OCT image before an applanation plate is applied to couple the laser surgical system to the eye, and the system control module is configured to control the placement of the laser pulses using the registering of the eye based on the non-OCT image, and the OCT image.

2. The laser surgical system of claim 1 , wherein:

the non-OCT imaging device is one of a microscope, a video microscope, a video camera, a CCD-sensor array, and a CMS-sensor array.

3. The laser surgical system of claim 1 , wherein:

the laser surgical system includes a diagnostic instrument; and

the system control module is configured to augment the non-OCT image with pre-operative information generated by the diagnostic instrument.

4. The laser surgical system of claim 3 , wherein:

the diagnostic instrument comprises at least one of a wavefront aberrometer and a corneal topography measuring device.

5. The laser surgical system of claim 1 , wherein:

the non-OCT imaging device is configured to generate

a pre-applanation non-OCT image before an applanation plate is applied to couple the laser surgical system to the eye, and

a post-applanation non-OCT image after the applanation plate is applied to couple the laser surgical system to the eye.

6. The laser surgical system of claim 5 , wherein:

the system control module is configured to register the eye to the laser surgical system based on the pre-applanation non-OCT image and the post-applanation non-OCT image.

7. The laser surgical system of claim 1 , wherein:

the system control module is configured to control the placement of the laser pulses for at least one of a cutting and a volume disruption.

8. The laser surgical system of claim 1 , wherein:

the system control module is configured to register the eye without a complete non-OCT image.

9. The laser surgical system of claim 1 , wherein:

the non-OCT imaging device comprises a third optical channel, at least partially separate from the optics module and from the OCT imaging device.

10. A method of performing laser surgery, the method comprising:

generating a non-Optical Coherence Tomography (non-OCT) image of an eye with a non-OCT imaging device comprising generating a non-OCT image before an applanation plate is applied to couple the laser surgical system to the eye;

registering the eye to a laser surgical system by a system control module based on the non-OCT image;

generating an OCT image of the eye;

generating laser pulses by a pulsed laser source;

directing and scanning the laser pulses in the eye by an optics module; and

controlling a placement of the laser pulses by the system control module based on

the registering of the eye by the non-OCT image, and

the OCT image.

11. The method of claim 10 , wherein the laser surgical system includes a diagnostic instrument, the method comprising:

generating pre-operative information by the diagnostic instrument; and

augmenting the non-OCT image by the system control module based on the pre-operative information generated by the diagnostic instrument.

12. The method of claim 10 , the generating a non-OCT image further comprises

generating a post-applanation non-OCT image after the applanation plate is applied to couple the laser surgical system to the eye.

13. The method of claim 12 , the registering comprising:

registering the eye to the laser surgical system by the system control module based on the pre-applanation non-OCT image and the post-applanation non-OCT image.
