I went for my annual eye exam and CL fitting this morning. Last
year I asked about Acuvue Advance, but J&J didn't have the -6.50
power I needed. I've been using a combination of Acuvue 2 (8.3 BC,
14.0) along with Ciba Focus N&D (8.4 BC, 13.8). Given that the
Advance came in the same parameters as the AV2, I was surprised
that my eye doc recommended the 8.7 BC, 14.0 in the Advance. I
tried them on and she checked how they did on my eyes. I've got
a prescription in hand for all three lenses. I'll try the Advance
for a few days before I decide what to order.

The Focus N&D were OK depending on conditions. After a while, my
eyes had a hard time wetting the lenses. I started to notice the
stiffness of the lenses at the end of the day. I'v never worn my
lenses overnight, but I've taken quick naps. AV2 was always
comfortable until they started drying up.

I trust my eye doc, but my question is more out of curiosity. Is
there typically a move to the flatter base curve with Acuvue
Advance?

It's good that you trust your eye doctor, as his/her judgement should
be preferred to someone who hasn't yet examined you.

However, my Acuvue Advance fitting distribution is about 80% 8.3 and
20% 8.7. This seems to be in agreement with just about everybody I
speak with, including some of their consultants.

Well - after about 4 days on the 8.7 Acuvue Advance, I'm finding that
the right lens occasionally feels loose. The left feels fine. It
felt like the time I had the wrong trial lens with the N&D. It just
started floating around a little bit before settling down for long
stretches.

Then I was going to try it again on Wed, and I thought I saw some
debris on the right lens. It was two little tears. I saved them,
and maybe my eye doc will want to see them. This morning I tried my
second trial pair. The right was intact. The left seemed a little
malformed at the edge, but I (stupidly) put it in anyways. I just
called up the doctor's office, and I'll be picking up a pair in the
steeper base curve.

I like the Acuvue Advance although I am having some initial fitting
problems. The "malformed" lens isn't giving me any problems,
although I'm just going to throw it away. It came in different
packaging - a rather large blister pack, and only said "Galyfilcon A

>From the makers of Acuvue". The right lens seemed to be in the

smaller Acuvue retail blister pack.

That's the original packaging of the trials when the lens was
introduced. Should be the same as one with identical parameters of the
smaller (newer) packaging, emphasis on "should".

My O.D. said it was otherwise identical. I've seen all sorts of
repackaging of contact lenses. I once had a single Biomedics 38 lens
to replace a torn "generic" equivalent (Proflex 38). Then I found out
all the "house brands" that Ocular Sciences produces, including
Proflex, Ultraflex, Optimedics, Mediflex, Polysoft, Aqualens,
Flextique, Sofmed, Versaflex, Target (for sale at Target stores), etc.
At a new eye doc, I got "Ultraflex 38", but she said I could have a
Biomedics 38 prescription if I wanted to shop elsewhere.

Oh - the new steeper base curve lens seems to be stable on the eye.
It might take a bit more adjustment time though. What was really
strange was that the 8.7 only felt loose periodically. It was fine
while sitting in the examination chair.
