I have dry eye after lasik, and irregular astigmastism, I have saw the Boston XO2 have more wettability, now I have been wearing Boston XO for 2 years. in my condition, if I wear boston XO2 ,can I get more comfortable? and more shapper vision? now, I often get red eye because of dry eye.

I think yes.. but I'm not sure since I'm not a doctor.
now I'm wearing Optimum Extreme with 125DK and its fantastic.
you not going to belive it.. but I'm wearing those lenses for 1 month and I don't feel it my eyes..
sometimes after 9-10 hours I put eye drops and that's it.
Boston xo2 have 141 DK..so I think its even better.

ask your dr for sure yang ,,i am surprised you have to wear contacts at all after having lasik surgery ????? usually the surgery corrects any problems

yangpinxiang · #5 (**permalink**) 04-30-2009, 11:55 PM

my eye have astigmastism since lasik in October 28th 2005,I have try many methods, but are all not useful. at last, I weat RGP lens, it work well, I can see quite clear. But there are some doctor say it is dangerous, contact lens could result infection. but except RGP, I could not find other way to improve my vision. I don't want to try the second surgery.

This is the reason I will not make this surgry.
since my doctor have a glusses, I have too.
if he will make the surgery for himself, I will make it too

oh i agree i would not get a second surgery either ,,and your dr was maybe referring to soft lenses because of infection ,,that is one good thing about RGP's

not alot of protein buildup or risk of infections because tears/solutions etc etc do not penetrate the lens i guess, glad you are having good luck with them

did you try the "Optimum Extreme?" because I think its the best until now.
I want to order the Boston XO2

dda1960 · #9 (**permalink**) 05-02-2009, 05:28 PM

not yet sim im still going thru some refitting problems with Boston ES i seen on the acculens it has a low DK but a very high wetting angle and with my dry eyes i think the wetting angle suits me better than having high DK but im going to look for a lens that has both and the XO2 is a option as well

as soon as i am done with refitting's then i can do some shopping

lol

Boston XO2's are fantastic rgp lenses! On occasion with a lack of sleep or insomnia I havve worn these lenses round the clock with zero adverse effects! The oxygen flow is extremely high and have also worn lenses overnight! So far the material is not approved for overnight wear but sits in the hyper dk class (not sure why)! The lenses feel moist on the eyes but do tend to deposit much quicker than lower dk materials so they have to be kept scrupulously clean to maintain comfort and long wearing times!

I also have dry sensitive eyes and this material has really been good for comfort! 4 stars goes to comfort!

The way you describe those contact lenses I don't see why you're not supposed to wear them overnight. Can you shed some light on this?

So does that mean you haven't actually slept in them, you just wore them for a long time? If so, how did you know that you were going to have insomnia and you could leave your contacts in?

Ha! I just noticed that you titled your post "Why Not?" and the next one was from Ynot.

weird....boston xo2 material is not approved for overnight wear however they are approved for VST which requires that u wear the lenses over night...

I don't get it....but YES I have slept in these lenses on occasion.

Slow down there. "VST" stands for "vision shaping treatment" right? The thing where you wear hard contact lenses overnight and they re-shape your corneas and correct your vision, right?

they are hyper gas permeable.....but for whatever reason they are not approved for extended overnight wear. I suspect because they get coated with protein and lipid deposits then lets say equal lens II material...

I have slept with these lenses and I can usually go overnight into the next day after having slept in them. They need to be cleaned by evening of the next day.

I think it costs alot $$$$$$$ to subject a lens through fda approval, but I beleive there are tests ongoing to test this as I read on contact lens spectrum.

wierd thing is they are approved for overnight vision shaping treatment which does require a patient to wear the lens over night but albeit taken out in the morning.

When you're doing the vision shaping treatment, you wear them only at night, correct?

That is weird. How can they be approved for overnight treatment, but not overnight wear?

Do those Boston XO2 lenses clean pretty easily after all that?

Maybe for the same reason you don't swallow pills unless you have to? (Just guessing here.)

I wanted to clarify about "wetteability". That refers the way normal and healthy tears spread over the biochemical surface of the materials. Wettability DOES not mean that the lenses hold moisture and wets dry eyes.

Hyper dk materials actually behaves like a dry lens on the eye because of the higher flourine or silicone content of the material. Dry eyes benefit fron rgp lenses becauae the can be fit to "tear pump" which means after each blink tears are forced underneath the lens. This is a fitting benefit and the increased wetteability of the material generally means less deposits sticking to the lens like a "teflon" effect. Therefore allowing the surface to remain cleaner helping tears spread uniformly over the surface after each blink.

That was a pretty long and complex answer, which I found very interesting and informative. I hope that yangpinxiang found it so as well.

Thanks, luvbostonxo2's. I found your explanation of wettability to be particularly helpful.
