Is Opti-Clean necessary for Oasys contacts?

I'm using Renu with Oasys and it seems OK.

Why is Opti recommended and what happens
if I don't want to spend the extra money for it?

Alcon, the makers of Optifree, did some additional testing on the
efficacy of their cleaning solution using silicon hydrogel (sihi)
lenses (like Oasys). the testing was submitted and approved to the
FDA. this allows them to make stronger claims, and gives them an
ability to market strongly. the makers of the sihi lenses also have
more certainty about the performance of that solution with their lenses
so they may recommend it.

Bausch and Lomb, who makes Renu, has done in house testing to show that
their product also works with sihi lenses. only it was not included in
their original FDA submission.

does that mean that Optifree is better than renu? probably not. IMHO
any of the solutions including most of the generic ones work equally.

Maybe you want to reread the question , it was about Opti-Clean, a cleaner
and quit different from the all-in one solution OptiFree.

If you are using your lenses for daily use and find that they require
better cleaning than that which occurs using Renu (when used with a
rub/rinse/store protocol), then you might need a separate cleaner like
Opti-Clean. I would use that along with Opti-Free for overnight
disinfection and not mix the products from the two companies.

BTW, make sure you are using the latest version of the products that say
"for use with silicone hydrogel lenses" The older versions of Renu and
Opti-Free are not the best choice with those lenses.

LB, O.D.

Certainly I know nothing about fancy contacts, but I would like to make
a suggestion.

When yours get ready for disposal, test them for cleaning with ordinary
cleaners, like Joy, for instance. Maybe some dilute isopropyl alcohol, though
that does not seem to be a good idea to me. Tears are pretty close to
isotonic saline, as far as ionic strength is concerned, so .85 per cent salt
would be a good candidate for the bulk of a cleaning solution. That could
be boiled to reasonably assure sterility. After cleaning, soaking in the saline
overnight should remove traces of detergent, alcohol, whatever.

I do know something about after-market scams. They are probably responsible
for a significant fraction of health-care hyperinflation.

So do your part, and post your results here, so that others can have the
benefits of your researches. Ignore the commentaries of the experts who
know what is best for you without having the slightest idea about the ingredients
of the products, which the manufacturers induce them, by perks, markups, and
other subterfuges, to recommend.

My best advice -- stick to simple eyeglasses so long as you are able, then
simple bifocals (with line) when the time comes. Avoid pitches for hard- and
antireflective coatings. Old peoples' reading/computer glasses are best as
single-vision. Single-vision reading/computer glasses might be good for
younger people if they sense eyestrain or worry about eye-glass related
progressive myopia. But then again, they might not. But cheap to try, if
you don't mind gambling on Internet sellers and can do simple arithmetic
on the prescription numbers.

On the other hand, my wife recommends that you spend as much as possible
on your eyeglasses, because that way you will be assured that your vision
will be as good as modern science can provide, and that it will not be
compromised by shoddy merchandise and reckless fitting.

How's your bottle doing in the closet? Anything growing
yet? I can see further savings here. Make your own saline,
store it in a closet, and when things start to grow in it you
can sell it to Ace.

It's good for several years. After that, spontaneous generation
takes over, and life starts evolving anew. Years later, one might
find Osama bL in one's closet, or King Kong -- who knows?

Ace wouldn't buy anything from me because, as far as he knows,
I am not a doctor.

I've always worn pretty plain ones. They worked fine for me.

People who make no money one way or the other strongly recommend against
making your own cleaning and saline solutions.

Won't argue with you, in general. However, the cost of sterile saline
and contact cleaners is negligible, over time.

Everybody I know, including myself, buys these things at the drugstore,
the supermarket or the chain store (I bought most at Costco). If you
wear standard contacts, you can buy them cheaper at Costco than the
doctor can buy them from the wholesaler (my brother was in the business,
but I don't know if it is still true).


> My best advice -- stick to simple eyeglasses

My best advice is not to wear any correction at all. That saves maximum
money and hassle. On the other hand, if you need correction, find out
what works best for you. That may or may not be what works best for
Dicky.

You must be quite the pair!

That's OK, neither is the guy currently supplying his mushrooms.

Somebody mentioned here that you had had some extraordinary vision problem.
But most people choose contacts to be pretty, a few for other reasons, like
athletic necessity, and a very small minority because their vision cannot be
adequately corrected in any other way.

In general, I think, contact lenses are a fancy solution, where eyeglasses would
do as well, possibly better, and certainly cheaper (well, if all the fancy options can
be passed by).

> People who make no money one way or the other strongly recommend against

My Dr. recommends Bayer baby aspirin. By the pound, it's probably over 100X as
expensive, maybe 1000X, as store brand. Well, he probably thinks I can't quarter
a pill to exactly 81.25 milligrams. Well, he is probably right. But I am working on it.

Everything, one-by-one, is. But in the end, altogether, the bills get difficult to pay.

My experience, at Costco, is spending too much money on stuff I didn't need
by getting things much cheaper in too-big packages. Usually I deal with Walgreens,
particularly for their specials. But when the time came to get some sodium fluoride
to make fluoride mouth wash by the gallon, they would not supply it, so I needed
to go to an independent pharmacy. By the way, the fluoride solution keeps well.

> My best advice is not to wear any correction at all.

That is not good advice. But finding a practitioner who can competently perform
a simple refraction without attempting to interest you in a lot of options that you
most likely do not need and to diagnose you for conditions you most likely do not
have, and will never, get, is very difficult these days in the so-called civilized world.

> On the other hand, if you need correction, find out what works best for you.

Aye, mate, there's the rub. There have been many proposals for what is best for
me. I have always favored the one that leads to the best corrected visual acuity.
But frequently I have been in the minority in that view.

> That may or may not be what works best for Dicky.

Some people may prefer to have their vision a bit blurry.

P.S. My local eye guy has got so flustered with all the gadgets he has to use to
fit contact lenses that he has clean forgot how to do the phoropter routine.
