Hi LJM and welcome.
I'm glad you got such a thorough exam to rule out 'back-of-the-eye' causes for what you're seeing. That would be a relief. Also glad also she's at least started you on the road to addressing the dry eye. I would encourage you to read up here in much more detail about what dry eye is, including the difference between evaporative type and aqueous deficient type, which will help you to ask more specific questions in these exams and also help you with getting more appropriate treatment. It's tempting for doctors to just throw drops and ointments at dry eye patients without really pinning it down in more detail. While this doctor may have been thorough in general tests, I don't see anything that suggests she was very thorough in tests specific to dry eye. Eyes sticking shut in the morning means something is going on that needs to be investigated in more detail, for sure, whether it's blepharitis, poor eyelid closure or something else.
As to visual effects from dry eye: Dry eye causes increased "higher order aberrations" which can mean some strange visual phenomena. Whether that could include the things you're describing specifically, I don't know (and frankly most doctors probably won't - even specialists don't have time to read ALL the studies on these things, let alone mainstream eye doctors). Might take some prowling around PubMed to figure that out.
So, did you never fill that astigmatism prescription? Did the new doctor find any astigmatism?
