Hello and thanks for your question, Mike. Yes, there can be microscopic little pits that form in the lens implant related to the laser that was done. Also, there can be deposits that form on the lens, but usually if that does happen, they are white blood cells deposits related to inflammation in and around the lens--this is quite rare.
I know your experience with past floaters has been that the floater seems to stay in the exact same place relative to the rest of your visual field no matter where or how you move your eyes. This is actually a bit abnormal for a floater. Usually floaters behave as you have described this spot behaving. They tend to trail behind the eye movements and you can see around them as they settle down in one position. The fact that you see this much more noticeably when there is more light is also another distinguishing characteristic of a floater. In this case, the only thing that can be done about the floater is surgery and it is a major surgery. That's not to say that it shouldn't be done. For persons with floaters that are significantly affecting their lives, the risks of the surgery become worthwhile and they mostly do very well afterwards.
