New Contacts Not Centered

I just switched to the Acuvue Advance soft contact, BC 8.3, and the
contacts are not centered on my cornea. They ride slightly high,
although the bottom still covers the lower portion of my cornea. Is
this a bad fit or is a small imperfection ok? My last type of contact,
Optima FW, BC 8.7, were centered on my cornea with excess around the
cornea equal in all directions. Any advice would be appreciated. Thanks.

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.

I was fitted for these, but the optometrist I went to doesn't have my
full confidence, hence my questioning here. I posited this to him and
he seemed to dismiss my concern but I guess if he okayed under the slit
lamp all should be good. Thanks.

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.
