Adjusting laser treatment in response to changes in the eye

1. A method comprising:

storing, by one or more memories, optical data from an optical recorder comprising at least two optical data sets by:

gathering a first optical data set of an eye with a pupil having a first pupil size; and

gathering a second optical data set of the eye with the pupil having a second pupil size;

determining, by one or more processors, a pseudo-rotation related to a pupil size change, a pseudo-rotation being a fake rotation where the eye just appears to be rotating;

receiving, by the one or more processors, a measured cyclotorsion, a cyclotorsion being a real or actual rotation of the eye;

calculating, by the one or more processors, an actual cyclotorsion from the measured cyclotorsion and the pseudo-rotation by subtracting the pseudo-rotation from the measured cyclotorsion; and

adjusting, by the one or more processors, a laser treatment to compensate for the actual cyclotorsion.

determining a first coordinate set indicating a first location of a feature of the eye from the first optical data set;

determining a second coordinate set indicating a second location of the feature of the eye from the second optical data set;

calculating a coordinate difference between the first coordinate set and the second coordinate set; and

calculating the pseudo-rotation using the coordinate difference.
