#$%^&*AU2020200658A120200220.pdf#####ABSTRACT The present disclosure provides a scanning system for treating target tissue in a patient's eye, comprising: an ultrafast laser source configures to deliver a laser beam comprising a plurality of laser pulses； an Optical Coherence Tomography (OCT) device configured to generate signals 5 which may be used to create an image of the cornea and limbus of the eye of the patient； a scanner configured to focus and direct the laser beam in a pattern within the cornea or limbus to create incisions therein； and a controller operatively coupled to the laser source and scanner programmed to determine a treatment pattern based upon the signals from the OCT device, the treatment pattern forming a cataract incision in the cornea or limbus that provides access for lens 0 removal instrumentation to a crystalline lens of the patient's eye and one or more relaxation incisions in the cornea or limbus, wherein a circumferential orientation and an angular extent of each of the one or more relaxation incisions are determined at least partly based on dimensions and an orientation of the cataract incision, and to control the scanner to scan the position of the laser beam in the treatment pattern.
