Does Lasik Cause Pupil Shift?

as my colleague dr coad said, you are confused

LASIK does not cause a pupil shift. you read an article saying that the pupil visual axis is not the same as the anatomical axis, so that's why we have the patients awake to fixate on the blinking light, as then their treatment is better centered than if we surgeons centered on what we thought was the (physical) center of the pupil

LASIK does not change pupil size but the laser treatment is centered on the visual axis (line of vision) and not the pupil center.  This may cause some confusion.

The short answer is no. Most human pupils have a slight natural shift in the nasal direction, though it is more evident in some than others. There is nothing in the laser vision correction(LASIK or PRK) process that would change this dynamic.
