INTRA-SURGICAL OPTICAL COHERENCE TOMOGRAPHIC IMAGING OF CATARACT PROCEDURES

摘要

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 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 target region; and an Optical Coherence Tomographic (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 OCT imaging system, and control the guiding optic to scan a second set of laser pulses according the modified scan pattern.

主权项

1. An ophthalmic surgical system, comprising:
a laser source, configured to generate a first set of laser pulses; a laser controller comprising a processor configured to:
generate an electronic representation of a first scan pattern; andcause a laser scanner to scan the first set of laser pulses according to a portion of the first scan pattern to create a first photo-disrupted region in a target region of an eye; and an Optical Coherence Tomographic (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; wherein the processor of the laser controller is further configured to:
generate an electronic representation of a modified scan pattern based on the image generated by the OCT imaging system; andcause the guiding optic to scan a second set of laser pulses according the modified scan pattern to create a second photo-disrupted region.
