...need to be spanked!
I'm gettin too old to deal with this...especially when using wrap compensators.
My two cents...what's yours?

Come on Barry, a little transposing never hurt anyone! :D
I have one MD who refers ALOT of patients to me. With the amount of patients he refers...........I would have to *spank* myself (back to reality) before I would ever vote for a "NO Plus Cylinder Rule"!
:cheers::cheers::cheers::cheers:
As long as it gets out of the doctors office and into my store I don't care how he writes it. If I can't read it or don't understand anything I call.
But then I still remember when plus cylinder was ground on the front, minus cylinder on the back.
I have even had practioners who occasionally wrote one eye in plus cylinder and the other in minus.

wait till you make, or have to make wrap transpositions regularly..
You will HATE plus cyl...

Hire an elf to transpose for you, I think there's one about to get fired in another thread :D
I work for an MD and deal with it everyday. The math is simple, especially since we are working with a relatively limited number set. However, I find myself constantly transposing to answer patient questions about Rx differences etc and of course always when calculating contact lens powers.
Barry, could you give us an example of how plus cylinder complicates your wrap Rx's? I am asking only out of curiosity and hope you won't take offense to me asking.
Perhaps this should be a separate thread, but why do MD's tend to write in plus cyl and OD's in minus?

The only time I see OD's use this is when they in an Opthamology clinic. My opinion is it makes them feel more like MD's. Now OD's do not get offended, that is my opinion but it just happens to happen every time in my experience.
ODs tend to have no choice when the autorefractor is set to +cyl and all the phorotptors are +cyl. ;)
Nothing to do with feeling important my friend.
I key the Rx into my computer, then click the "transpose" button. :bbg:
...Just ask me...
I use Darryl's wrap compensator. I have it set to a precision of 0.01D. Since I *evaluate* the compensated Rx, the starting Rx, the previous Rx history (which usually is in minus cyl), and the expected Rx progression when I decide how to order and tolerance the wrap eyewear, and that the compensator *only* gives results in minus cyl form...well..it is just easier if they are all in the same cyl convention. There is simply less chance of mistakes being made.
No matter how you slice it, I see no excuse for continued use of "+" cyl form. Some might say I'm lazy. But I'll counter that the refractionist is too lazy to "get with the program" in the new millenium.
FWIW

I really fail to see the problem here. Transposing from plus cyl to minus cyl is so easy that you ought to be able to do it in your head without barely giving it a second thought, (except to double check of course).
I think the original poster's intent may be misplaced or is trying to take a swipe at optometrists. What a ridiculous post.
1. A plus cylinder prescriptiondon't mean you have to dispense as plus cylinder base curve lens form.
2. If you cannot transpose, don't accept the Rx's.
3. If you're so upset, tell the prescribing doctor so the doctor can send the Rx somewhere else.
Chip,
I can remember when I used to rock them cylinders in. I bet you do too!

IMO, it has pretty much everything to do with who buys the equipment, or what equipment was there to begin with. The autorefractors may have a neat little button to switch from + to -, but the phoropters rarely do :)
I doubt there are any ODs who feel more *special* because they write a prescription in +cyl.
The answer is really simple, Jack Copeland taught refraction at most medical schools. Jack thought +cylinder was better. Of course he also thought myopes were geneticly inferior to hyperopes.
He carried a retinasocpe (skiascope) with him at all times (copeland streak) and married a hyperoptic woman to avoid having myoptic children.
You guessed it, he had myoptic daughters.

On a related vien, Archie Manning married a tall woman so he would have tall sons, that worked.
G. Gordon Liddy married a mathmatics prodigy to have intelligent children, that supposedly worked at least in his view.
We have an opthalmologist nearby that works in - cyl. He is the only one near us. Is this rare or very rare?
