PureVision contacts: are they safe to sleep in?

I wear PureVision Toric contacts (balafilcon A), visibility tinted.

Nowhere on the box is written that they are extended wear.
Though in newsgroups it's frequently mentioned that
PureVision are extened wear and I can wear them up to 6 days.
Also doctor told me: yes, you can sleep in them.

So are all PureVision lenses extended wear and it's safe to have
them uninterrupted for 6 days?

I am just trying to be safe.

AFAIK, Purevision is approved in the U.S. for 30 day continuous wear.

Safety is a relative term. Bad things can still happen, and they
happen more often in the group who wear their lenses continuously.

Purevision (Bausch & Lomb) are approved in the USA for 30 days of
continuous wear, day and night. I have a few patients who do that
although for people that desire overnight use, I usually recommend one
week extended wear with a careful explanation as follows:

1. There is a theoretical and slight risk of complications, compared to
daily wear use, at one week continuous wear which increases with
additional wearing time. That risk is actually *lower* than for those
people who use their lenses on a daily wear basis and who do not follow
appropriate lens care and handling protocols. Like cleaning and
disinfection between use and washing hands before handling the lenses.

2. Never sleep in a lens that is uncomfortable or if you have any signs
or symptoms that something is nor right, like redness, light
sensitivity, blurred vision and, of course, pain.

3. If you experience the above, see you doctor immediately. It's easy to
fix the problem sooner than later.

You could consider refractive surgery. Then you wouldn't have to deal
with contacts at all.

NO!!!!!!! Bad idea! Much riskier than contacts! Either wear contacts(or
get orthoK) or stick with glasses! Try not to sleep in contacts(unless
its orthoK) because the risks of 24/7 contacts shoot up 10-20 fold! Why
risk your eyes sleeping in non orthoK contacts just to save the 30
seconds it takes to pop them out before bed???????

The retard has no experience regarding contacts, no education
regarding anything else and just portrays himself to be an "expert".
he's just an internet troll.

I understand overnight orthok is not FDA approved in the States Ace, so
can't see how you could do that even if you wanted to ?

It can be done "off label" by a licensed optometrist. Who cares about
FDA approval, they have approved unsafe things all the time. Many
people say lasik should have never been FDA approved. Even the
anti-lasik say orthoK is reasonably safe to go ahead with, so are RGP
contacts. In fact some damaged by lasik resort to RGPs to improve their
poor vision that lasik has left them with.


Dont mind Serebel, he just insults, never offers constructive advice.

There are 5 OK lenses approved for ON wear. BE Retainer, Dream Lens,
Emerald and R&R are all part of the Boston group and CRT from Paragon.
Menicon Z-CRT is pending approval.

Excellent news. More info will flow through about effects of orthok,
the more that people use it. I'm in Australia and using it. About time
the States caught up with us in Australia !
