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.
