Registration of LOI fiducials with camera

A laser eye surgical system, comprising:

• a laser source for generating a first electromagnetic radiation beam;
• an imaging system configured to image an eye of a patient;
• a patient interface configured to interface with the eye of the patient, through which the first electromagnetic radiation beam is directed to the eye of the patient, the patient interface having,
• a cup with a large and small opening and a notched interior rim;
• a scanning assembly mechanically coupled to the patient interface and operable to scan a focal point of the first electromagnetic radiation beam to different locations within the eye;
• an optical path configured to propagate the first electromagnetic radiation beam from the laser source to the focal point and also configured to propagate a reflected electromagnetic radiation beam, reflected from a focal point location, back along the optical path, the optical path comprising a first optical element disposed in the propagation path from the laser source to the focal point,
• the first optical element being configured to receive the first electromagnetic radiation beam, and to output a first portion of the first electromagnetic radiation beam, which is less than 20% of the first electromagnetic radiation beam, in a first direction toward the focal point and output a second portion of the first electromagnetic radiation beam in a second direction which is different from the first direction, the first optical element further configured to receive the reflected electromagnetic radiation beam, traveling in a third direction which is opposite the first direction, and to output a first portion of the reflected electromagnetic radiation beam, which is greater than 80% of the reflected electromagnetic radiation beam, to a fourth direction;
• a detection assembly configured to receive the first portion of the reflected electromagnetic radiation beam that has been output by the first optical element to the fourth direction, and in response to the received first portion of the reflected electromagnetic radiation beam to generate an intensity signal indicative of an intensity of the received first portion of the reflected electromagnetic radiation beam;
• a bypass assembly configured to be reversibly inserted into the optical path to divert the first electromagnetic radiation beam along a diversion optical path around the first optical element, the bypass assembly being configured to be moved to a first position in the optical path wherein the bypass assembly directs the first electromagnetic radiation beam to bypass the first optical element and delivers the first electromagnetic radiation beam to the eye of the patient at a treatment power level, and wherein the bypass assembly is further configured to be moved to a second position out of the optical path where the bypass assembly is out of beam paths that pass through the first optical element such that the first optical element delivers the first electromagnetic radiation beam to the eye of the patient at an imaging power level which is less than the treatment power level;
• and
• a controller operatively coupled to the laser source, the imaging apparatus, the bypass assembly, and the scanning assembly, the controller configured to:
• receive one or more parameters defining one or more ocular incisions;
• image the eye with the imaging apparatus and identify an expected scan location within the image corresponding to the one or more ocular incisions based on the one or more parameters;
• and
• control the scanning assembly to scan the focal point of a laser beam.
