Medical Forum / General / Vision / January 2006Is 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. > Alcon, the makers of Optifree Maybe you want to reread the question , it was about Opti-Clean, a cleaner and quit different from the all-in one solution OptiFree.  SignatureJan (normally Dutch spoken) > 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? 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. -- Dicky Magooeyes.

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

Ace wouldn't buy anything from me because, as far as he knows, I am not a doctor. -- Dicky >> I can see further savings here.

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. > 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. You must be quite the pair! SignatureDan Abel dabel@sonic.net Petaluma, California, USA > I've always worn pretty plain (contact lenses). They worked fine for me. 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 > making your own cleaning and saline solutions. 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. > Won't argue with you, in general. However, the cost of sterile saline > and contact cleaners is negligible, over time. Everything, one-by-one, is. But in the end, altogether, the bills get difficult to pay. > 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 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. -- Dicky 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. > > I've always worn pretty plain (contact lenses).

Mine is a sample size of one, so I would be interested in hearing from those who have a larger sample size. Do people in fact get them to look pretty? I know a lot of guys who wear contacts, and I doubt that many of them wear the contacts to improve their looks. I haven't asked, though. > > People who make no money one way or the other strongly recommend against > > making your own cleaning and saline solutions.

Those little aspirin are big business. Do you have some numbers here? From the last few years? Walgreens is selling Bayer baby aspirin for US$.04, and a generic on sale for US$.02: http://www.walgreens.com/store/productlist.jsp?CATID=100072&navAction=pus h&navCount=12&selectedBrand=&page=2&orderBy= I pay US$2.75 for a bottle of 400 at Costco, generic. They have Bayer baby for US$10.99 for 365. > > My best advice is not to wear any correction at all. > > That is not good advice.

As a high hyperope, contact lenses offer far better optics for me than glasses, including peripheral vision ... largely absent with glasses. For hyperopes, contact lenses stimulate less accommodation than do eyeglasses (critical for me). Contact lenses act as a corneal bandage to help ameliorate the effects of my dry eyes. Contact lenses allow me to wear close-fitting, wraparound sunglasses to battle the elements outdoors. With a high Rx, getting a prescription pair to do that is well nigh impossible. SignatureLive simply so that others may simply live > For hyperopes, contact lenses stimulate less accommodation than do > eyeglasses (critical for me). In this particular subculture. *accommodation* seems to mean something other than I thought it to mean. Here it is presented as an undesirable consequence of contact lens use. Elsewhere in these posts it is represented as a cause of myopia. Is there any consensus on what the word means. > Contact lenses act as a corneal bandage to help ameliorate the effects > of my dry eyes. My suspicion is that they are generally more irritating than ameliorative. But I suppose that once you have started shelling out their cost, it is comforting to look for some reasons you might have gone for them. > Contact lenses allow me to wear close-fitting, wraparound sunglasses > to battle the elements outdoors. I get that too, but with IOL implants (hopefully lower upkeep than contacts). Now it's said possible to have accommodating IOL's, but I don't believe that either, assuming I know what *accommodating* means. Valiantly battling the elements, -- Dicky http://home.att.net/~muffkat/Me-in-shades.jpg Can we get back on point. What is the best commercially sold solution for maintaining Oasys contacts lenses. I have seen some positive information on a new solution from Alcon called Opti-Replenish, but have not had any experience with it. |
