We have been having issues with our lab in regard to cutting lenses based on an archived pattern. Some will come in too large, some too small. Ideally, we would rather send the patient's frame when possible but as you all know, that is just not possible all of the time. I had read that taking the lens circumference is helpful to the lab in cases like this. Is there any type of guideline to follow in how often we should take this measurement, and does it really help the lab?
Thanks!
