Abstract

A cataract surgical system includes a laser source to generate a first set of laser pulses; a guiding optic to guide the first set of laser pulses to a cataract target region in an eye; a laser controller to generate an electronic representation of a target scan pattern, and to control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the cataract target region; and a Spectral Domain Optical Coherence Tomographic (SD-OCT) imaging system to generate an image of a portion of the first photo-disrupted region. The laser controller can generate an electronic representation of a modified scan pattern in relation to the image generated by the SD-OCT imaging system, and control the guiding optic to scan a second set of laser pulses according the modified scan pattern.

Claims22

Dependent claims

A cataract surgical system, comprising:

a laser source, configured to generate a first set of laser pulses;
a guiding optic, coupled to the laser source, configured to guide the first set of laser pulses to a cataract target region in an eye;
a laser controller, configured
to generate an electronic representation of a target scan pattern, and
to control the guiding optic to scan the first set of laser pulses according to a portion of the target scan pattern to create a first photo-disrupted region in the cataract target region;
and
a Spectral Domain Optical Coherence Tomographic (SD-OCT) imaging system, configured to generate an image that includes a portion of the first photo-disrupted region with an image resolution in the range of 0.5-5 million image points per image and a frame-rate in the range of 20-200 frames/sec;
wherein
the laser controller is configured
to generate an electronic representation of a modified scan pattern in relation to the image generated by the SD-OCT imaging system, and
to control the guiding optic to scan a second set of laser pulses according the modified scan pattern to create a second photo-disrupted region.
