Robert, my apologies if you were offended by anything I said or omitted.
Here is drk's response in post #8:Thanks for the confidence in optometry. I hope we reciprocate the confidence in your profession.
Prism correction is not exact, so don't worry about the relationship between add power/working distance and prism. (This would only apply in a near vision only application, anyway.)
Secondly, the prism correction most of the time to be worn in distance and near gaze, and an add of whatever power has no bearing on the amount.
My comments:
- I don't know who drk was responding to in his first sentence since he did not quote anyone. There is a lot of banter in this thread between posters, and most of it is not directly related to me.
- My understanding from talking to patient is that the prism is in the reading area/near gaze of the person I am referring to, so I did not know what to make of drk's last comment. It is completely unfair for me to expect a definitive answer since he cannot examine or even talk to the patient. But I was not sure if his advice was applicable to this particular patient, so that was one reason I did not acknowdge his "answer."
- Drk did respond, and I thank him for that, but ml43 basically said prism is over-prescribed and probably should not used in the vast majority of cases to begin with. I find that very interesting, but I have no idea who to believe.
- My response was to Uncle Fester who did not seem to understand what I was saying about whether the prism would change if the add power changed. I was not responding to you or drk at that point, just trying to clarify for Uncle Fester. Admittedly, it is unfair to ask for advice when I am explaining a situation that I don't even have all the facts about, and I am not the patient.
- Despite what a lot of people in this thread said (most of whom I trust a great deal), according to the patient, they had a very hard time finding any OD or OP who would refract someone with a prism. I am just getting this third hand, and don't know if that is correct, whether it is local phenomenon, or whether it is completely wrong.
- Again, sorry for any confusion or if anyone was offended by my remarks.
