Sometimes dropping your A1c fast can cause some eye damage also, you could be seeing the tail end of things getting better...your next visit could be perfect.
I would recommend that you stick with a doctor that has modern equipment and can take photos of your eyes every year and look back to see if there is some type of progression. You have 20/20 vision your fine...my brother is a pilot, 69 years old and is insulin dependent...he is required to see his Endo and flight doctor every three months, they can't find a reason to suspend him so he just keeps flying.
