Thanks in advance for any advice.

I am still in the trial period at lens center type place. Looking for
soft contacts with -.1 in left eye only, the right eye is fine for
reading and intermediate on its' own. Last prescribed contacts were two
years ago, and were 1 day acuvue with base curve of 8.5, diameter of
14.2. Before that, they were CSI with base curve of 14.8, diameter of
8.6, -5. t

Tried Purevision base curve of 8.7, diameter of 14. and vision is good,
but it just feels too obvious. Soaked it overnight in Replenish and it
did help, but still didn't solve the problem.

Recently tried Biomedics 55 Premier which is aspheric. Vision was
amazing the first day. Hazier the next. First tried soaking in Clear
Care, and then with Replenish. Nothing really made it go back to great
vision. Doing my own research,I found out about the new Biomedics XC,
and was waiting for this center to get it in (after I asked them to
look into it), but the rep hasn't even called them back about it.

Tried the acuvue oasys, and it is like a dream. No problem with the
lens getting dry, oily or protein deposits on it, which I have had
problems with in the past. However, the vision is not crisp. I really
want this lens to work, though.

Walked into another contact lens center inquiring whether they had the
XC in stock. They did, and there was a doc at the front counter, who
was interested in my case. She said that I probably couldn't see as
well out of the oasys because the base curve was too small: 8.4.
She said that was the problem, and that I should try the Acuvue Advance
because it comes in a base curve of 8.7. Having already looked into
the advance on this forum, and seen that some of you doctors have sent
it back, I don't think that is a good idea. I thought that I could just
up the prescription in the oasys to -.125, or what ever the next step
up is in the oasys, and that might solve the problem. She didn't think
that would solve the problem, because she said Johnson & Johnson lenses
were already generally stronger than other companies.

What do you think? Can I wear the oasys? Should I hold out for the XC?
Should I just get something now and wait for the Biofinity, which may
be like the Biomedics Premier, but in silicone hydrogel, I saw
somewhere that it is due to be realeased in July 2006?

Sorry for the long winded post, but I tried to get all the facts for
you.

Gratefully,
Chipster

It's hard to solve this problem without actually observing the lens on your
eye and overrefracting. If you'll allow me to take some pot-shots...

Purevision only comes in one base curve, and it's 8.6.

Soaking isn't the best cleaning technique - rubbing is generally better than
not rubbing. I still start the washing machine rather than just letting the
clothes soak.

That's what overrefraction is for.

Too-steep lenses can interfere with vision but it usually varies with each
blink - excess tears under the pouching lens get "squished" out with each
blink, and slowly refill between blinks.

I haven't sent my Advance lenses back. I might, but I find it improbable
that one lens will fit everybody.

That would be news. Every lens has manufacturing tolerances and you might
have gotten a misrepresentative sample. Regardless, an opinion doesn't weigh
well against the value of overrefraction. Evidently that doctor hasn't
overrefracted many J&J lenses.

I do like the Oasys. I think you should try another one on and see what
a -0.25 handheld trial lens does for distance VA, as well as a +0.25. That's
"overrefraction."

Thanks for your reply Mike. Went back to doc and she said that the -1
is right for me. It must not be as clear as some of the others because
it has no aspheric optics. I can see well enough with it though, and it
is worth the slight blurriness at this point, because the comfort of it
is so high.
