Hi Kram
I hope your are in better condition after 3rd FOV and your vision still improve with time. 
I had FOV one year ago on my left eye and after that i got problem similar to your frill ( I've read your post in forum) but my frill had changed since a year ago and move from far periphery to next into my central vision i can easily focus on it and see very sharp edge also i have some lines in bottom and top of my vision and one target cell in my vision !
after your last FOV how much of your problem do you think has fade? do you still feel and see  your frill?
I've visited another local doctor who can do FOV on my eye but he doesn't do sclera depression and peripheral vitrectomy. because of this i have much doubt he can improve my condition.
thanks
