That's what your provider is supposed to do- to get you the correct fit
(I assume that
you did get refit by a provider and not by self-fitting). The fee(s)
that you were/are
charged should cover follow-up visits to ensure a proper fit. Without
looking at
your fit with a slit lamp, there's no way I can tell you if you have a
safe and
adequate fit or not. IOW, see your provider for your concerns.

What matters is the comfort. If they feel good all day, decentration isn't
important.

Having fit a number of Acuvue Advance lenses, I have observed that they
do sometimes have a tendency of riding slightly superior.  However, no
patient has ever objected to this, or even indicated that they had
noticed.  As long as there is no lower edge liftoff, I fail to see a
problem.

There are other silicone hydrogel lenses, namely Focus N&D, O2Optix,
and Purevision beginning in April.  As an optometrist who wears contact
lenses, I am far happier in a silicone-hydrogel lens than in any
previous kind of lens, and would not recommend that any of my patients
go back to 35+ year/old technology just to achieve a perfectly-centered
lens.
