Are ProClear Toric Multifocal contacts okay for extended wear?
Have been wearing Bausch and Lomb MultiFocals for 30 days continuous wear with no problems and I love them. Problem is that my astigmatism has reared its ugly head (wore old-style hard and RBP lenses for years and it sort of held that in check). Doc has ordered a trial pair of ProClear Toric Multifocals, as they can treat my myopia, astigimatism and presbyopia (ah, the joys of getting older) in one lens. Can't find a lot of information about these lenses online. They are made of omafilcon A and are a 30-day disposable, but I don't know if they're okay for continuous wear like my B&L lenses. Also looks like it's a different style of correction -- switching powers for dominant and non-dominant eye...sounds like I've got a huge learning curve ahead. But back to the original question -- can I use these as extended wear lenses? I truly have enjoyed being able to see when I wake up in the morning...
If you were sleeping in your lenses, I hope you were wearing Pure Vision Multifocals. They are silicon hydrogel lenses, the newest lens material that allows more oxygen to pass through. ProClear are conventional hydrogels and are not extended wear. I don't think there is an option that is both a bifocal and toric that is approved for extended wear. There are several toric lenses approved for up to six nights of continuous wear. Your doctor could use one of these to give you a mono-vision fit.
