Medical Forum / General / Vision / November 2006Are there any daily disposable contact lenses made from Silicone Hydrogel?
Just wondering if there any daily disposable contact lenses made from Silicone Hydrogel or if anyone knows that any company is working on introducing one. Thanks. > Just wondering if there any daily disposable contact lenses made from > Silicone Hydrogel or if anyone knows that any company is working on > introducing one. > Thanks. Highly doubtful. DrG >Just wondering if there any daily disposable contact lenses made from >Silicone Hydrogel No. >or if anyone knows that any company is working on introducing one. I spoke to our Vistakon rep and they didn't see a market for it. I would welcome such a product because all daily disposable SCLs are standard hydrogels, and as such aren't nearly as good for a lot of dry-eyed patients as silicone hydrogels are. IOW, the DRY EYED patient who either soils their lenses rapidly, values convenience, and/or has extremely dry eyes would appreciate such a product. > I would welcome such a product because all daily disposable SCLs are > standard hydrogels, and as such aren't nearly as good for a lot of > dry-eyed patients as silicone hydrogels are.

In a perfect world people would be willing to pay for them. Perhaps in a few years, when the development costs have been amortized, first generation silicone-hydrogel materials will make their way into daily disposable lenses at a cost people would be willing to pay. As it is, people balk at paying the premium for the current daily disposables.

Both the Ciba and Bausch silicones require surface plasma treatment, and so are expensive to produce. The newer generation (Oasys, Advance and Biofinity) do not require surface treatments and so are cheaper to manufacture. It is this type of lens that will most likely make it as a daily disposable one day > > I would welcome such a product because all daily disposable SCLs are > > standard hydrogels, and as such aren't nearly as good for a lot of [quoted text clipped - 9 lines] > > DrG Its not so much the high cost of the R&D, but the cost of goods of each lens.

It is this type of lens that will most likely make it as a daily disposable one day This thread caught my eye(sorry), as this is exactly what I would use if available too. I've gone away from wearing contacts everyday to now only wearing occasionally(weekends, nites out, etc.). No matter how comfortable contacts have become, I still prefer to wear my glasses most of the time, so I would be willing to pay a bit more(not a ridiculous amount more) for the best feeling daily disposables. I think there are many more[now and then wearers], like me out there that would appreciate the silicone hydrogel daily disposables... and be willing to pay a bit more for them.

Many patients balk at the cost. Naturally, I would be perfectly happy to have si-hy dailies available, but I'm not going to be holding my breath. Why are you not wearing some brand of daily disposable now? The only logical reason for such a lens is some form of dry eye. The reasoning behind the development of si-hy lenses was for improved safety during overnight wear....the antithesis of daily disposables.

DrG > Dr. Leukomia, > [quoted text clipped - 40 lines] > > > > > > > >DrG I honestly have no idea. At my last eye exam, the eye doctor told me that the pressure in my eye was borderline high. I'm only 25 years old. He then said that even though it was high, he wasn't too worried about glaucoma because my nerves looked very pink and healthy. I'm not sure pressure would have anything to do with eye redness though. But, really I think perhaps sitting in front of a computer for hours everyday could have something to do with it. But, then again, maybe not. I have worn a silicone-hydrogel (Focus Night and Day) for the last 3-4 months or so, and I take them out every night. Honestly, I have not seen any noticeable improvement in comfort or redness with these lenses, although they haven't been any worse either. SOmetimes at night I'll be looking at the computer screen and just my eyes will start almost tearing up. I know then it's time to put on the glasses. > What is the cause of your redness?

I have some patients who get deposits on their lenses so quick that within 3-4 days they are totally coated. daily disposables are good for them. also for "recovered" GPC sufferers. after you get them cleared up, if they stay clean they usually won't relapse. snip > Why are you not wearing some brand of daily disposable now?

Well, my son wears Ciba Focus Dailies because of severe allergies. He might also benefit from a daily silicone-hydrogel lens because his lenses dry out. Daily disposables = good for allergies and GPC Silicone-hydrogels = good for *some* forms of dry eye Daily silicone-hydrogel disposables = good for allergies and some forms of dry eye DrG |
