Longshott the remaining debris can take quite a long time to dissapear, i found it took over a year with my first vitrectomy, the only remaining floater was too large to be filtered out by my eyes natural system ,but the rest of the fluid in my eye became acceptably clear after tons of crud post op , to be honest i dont think its possible for your eye to be completely clear after a vitrectomy, i can always find something, a cell or a black dot if i look for it but that's acceptable compared to the hundreds of strings and cobwebs people with floaters suffer , just remember things will only improve, rather than get worse which is the case with syneresis or PVD
