1. A method for altering an eye color of a patient with a color alteration procedure, the method comprising:
generating a scanning pattern for a delivery of laser power to at least 50% of an anterior surface of an iris of the patient during the color alteration procedure;
tracking, with an optical tracking system, an axial alignment of an eye of the patient during the color alteration procedure;
setting a laser system to deliver a first laser power to a location in the eye of the patient, wherein the first laser power is sufficient to cause elimination of at least a portion of stromal pigment in the iris of the eye;
delivering, with the laser system and according to the scanning pattern, laser light to the eye at the first laser power;
determining an amount that the eye is off axis based on the axial alignment;
comparing the amount to a first threshold amount;
setting the laser system to a second laser power based on determining that the amount equals or exceeds the first threshold amount, wherein the second laser power is less than the first laser power; and
delivering, with the laser system and according to the scanning pattern, laser light to the eye at the second laser power.
