questions about prism correction and contact lenses

I would like to know if it there are any contact lenses with prism
correction. For instance RGP lenses? If so, how when where, what does
it cost???
If not, if it is expected to become available sometime?

Furthermore i was hoping somebody could tell me whether contact lenses
can be combined with glasses containing a prism correction. Would like
to use lenses for sports and stuff and prism correction only for
reading, computer and tv (which is 80% of my average day usage)

Can prism glasses with cylinders and about +2 correction be used with
those color lenses? (no correction in the lenses ofcourse, just
another color)?

And according to my info, prism correction is not available by lasik
techniques? Why not? Is it expected to be in the future?

Thanks alot for anybody who provides me with some information
regarding these questions!!

 

Hi,

No, not yet.

IMHO no. The lens is "swimming" on top of your tear layer. And due to
gravity the prism's base side will turn down for the lens is thicker
and therefore heavier there. So it's not possible to fulfill your
prismatic needs with a contact lens.

As long as your eyes fulfill all requirements for wearing lenses, no
problem.

Same as above.

IMHO not. Creating a prismatic cornea will lead to a stair effect on
the prism's base side which will cause much more problems than help.

And by the way: In my eyes LASIK is a crime. Visit
www.lasikdisaster.com for more info on my opinion.

You're welcome.

thank you for your reply sascha!

and lasik is indeed a crime, since ive had 2 intakes and in both cases
i was found ok for lasik treatment. This was pre-prism.

So i guess i would have came out worse. A true quick money scame
indeed.

 

Except that his information is incorrect.

You can have prism in contact lenses. It does, however, depend upon how
much prism and in whch direction the image needs to be shifted. And that
would apply to RGP or soft lenses.

Hi there,

Well, I don't think so.

And what idid I say, that#s different to that?

An overcorrection has not so much in common with a prism correction.
You can even have a prism correction without dipotric power. That is
what I wear to support my vision.

you mean a scleral lens wont turn heaviest side down? How will you
stabilize it?

Hi,

great idea. Have you already applied for the Nobel Prize with that
brilliant idea?

I have prescribed prism in a contact lens with variable results, but nobody
ever said it would be practical, joker. As far as decentration goes, there
are parallels in the literature concerning decentered LASIK ablations, in
which strabismus was induced as a result.

You're right, we're agreeing. Puzzled by Larry's answer that he can
fit cl's with incorporated prism - there isn't anything for bi/bo and
even verticals are impractical other than possibly getting anything
other by an accident to what the patient needs.

The origninal posters conclusion is correct- just wear the glasses with
prism.

However, as a pure "thought problem," it could be done with a scleral lens,
and without Super Glue. I think that H/Buttner could tell us how this
could be accomplished.
