1) Do you have any idea when they might be coming out? Any info about them
on the web?

2) I wore GP lenses for most of my adult life. I only changed to softs (only
si-hys) a few years ago. So yes, I could wear GPs, which I understand have
some better characteristics for vision. However, I have become used to the
comfort of the softs now, and the convenience of EW. (I take out the lenses
and clean them overnight once per week, as well as changing the lenses each
month.) Also, peripheral vision is better with softs, due to the larger
lenses. Also, with GPs, more than once, for instance on a windy day, a lens
would fall out of my eye, and I couldn't find it. Then I would have to wear
glasses for weeks, while waiting for a new lens. With the softs, besides not
falling out, they are so easily replaceable if need be.

Do you think GP multifocals are better? Which kinds in particular?

I believe that both Ciba and Vistakon have multifocals in the works.
Have you ever considered trying GP lenses?

I have not tried the Ciba Focus Progressives, but it was my
understanding that the add power was low, maybe about +0.75. The
Purevision is available in 2 adds, "low" and "high." In general, the
quality of the distance vision is inversely related to the value of
the add. So, my question is what add were you wearing in the
Purevision? At 59 years, you probably need the "high" add. I usually
try to compensate for this by using a low add in the dominant eye,
FWIW.

Getting good distance and good near with a MF contact lens requires a
little compromise. Did your doctor try modified mono vision, using
the multifocal in both eyes but optimizing one for distance and one
for near? I find good success with the B&Lwhen fitting older
presbyopes by using a low add in the dominant eye and a high add in
the near eye. Worth a try.

Dr Judy

-----------------

Hi Dr. Judy,

Is the high add really high enough for older presbyopes?

I am 56, myopic and presbyopic. I tried the PV MFs once. I think both were
high add, but did not give me good enough near vision from the add. We had
to keep lowering the power of the myopia prescription on the left eye, so
that I could finally read with them, but it was lowered so much, that it was
not really much different from regular monovision, except less clear
distance vision.

I wish they would come out with more types of Si-hy multifocals. Does anyone
here know, if anything new will be coming out in the near future?

Getting good distance and good near with a MF contact lens requires a
little compromise. Did your doctor try modified mono vision, using
the multifocal in both eyes but optimizing one for distance and one
for near? I find good success with the B&Lwhen fitting older
presbyopes by using a low add in the dominant eye and a high add in
the near eye. Worth a try.

The Purevision lenses would probably be better for your eyes--as being
silicon hydrogel, let more oxygen in.

I'm surprised that Purevision is still the only si-hy multifocal available.
With an increasing number of si-hy regular lenses available, even a few now
in toric versions, why still only one multifocal version? For instance--Ciba
has two silicon hydrogel lenses out--Focus Night and Day (I believe still
the highest oxygen transmissibility (dk/t) available),and AirOptix. (Also
now, Airoptix Aqua, so perhaps three.) Airoptix now available in toric as
well. Why not multifocal?

One would think that with the phenomenon of the aging baby-boomers, there
would be an increase in multifocal models available, new multifocal
technologies, etc. but unfortunately that does not seem to be the case, at
least as of now.

Thanks for the input, but I don't want glasses. I get almost as good as
vision as with glasses with the CIBA's without scratched lenses, dirty
lenses, misplaced glasses, sat on frames, etc. I don't think I ever want
the 'advantage' of glasses.

I will stay with Focus Progressives and occasionally try other similar
products to see how they work for me. B&L didn't pass the test.

If I had problems like that I would go for glasses!

Maybe. Or maybe you were just over-plussed in the B&L. Can't tell.

Thanks so much for the reply.

I tried the B&L for 3 days and went back to my OD for a follow up check. I
really can't see how I can keep them. I have to strain to get part of the
20/25 line, and I had 20/20 with the CIBA's.

Out in the world, I couldn't read many signs within a half of a block
(depending on the size, of course).
I can see the same ones clearly with the Focus Progressives.

One advantage the B&L had was that, what I call, the near-immediate distance
was clearer. About 5 to 7 feet. This comes into play when someone asks me
about some on their computer screen while they are seated at their computer.
I couldn't read much with CIBA and could see that better with the B&L.

Oh well. It's all a matter of trade offs. I still opt for contacts over
eye glasses. They are just more convenient for me, even though eye glasses
give crisp vision. I will keep the Focus Progressives.
