Hi @freehotdawgs (Stephen) I am sorry to hear about your experiences. After asking around, there does not appear to be any reports of issues following laser eye surgery. Unfortunately whilst we do endevour to ensure our eye trackers for as many different types of people as possible, there sometimes are those that have significantly great difficulties that others as you have already found out.
It might however be worth ensuring that you are not positioned next to a light source such as window or spot light to see if this has any effect on you trackability. If you are on a laptop, have a test around the house and let us know how it goes.
