A cataract surgical system, includes: 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; and a Swept-Source Optical Coherence Tomographic (SS-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 0.5-10 million image points per image and a frame-rate in the range of 20-500 frames/sec. The laser controller is 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 to generate an electronic representation of a modified scan pattern in relation to the image generated by the SS-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.
