Looking at the Rx, I am curious why the OS rather than the OD, since the OD is the near oblique. What is the patient's BVA in each eye? Which eye is dominant?
BTW, you mentioned that you observed 1D BU in OD. Without that 1D BU, this is approximately the prism you would have.
OD -3.0625 @ 10 mm below OC would result in .30625 Prism BD OS -2.5125 @ 10 mm below OC would result in .25125 Prism BD
Resulting in 0.055 prism vertical imbalance.
With it, this is what you would have.
OD -3.0625 @ 10 mm below OC would result in .69375 Prism BU OS -2.5125 @ 10 mm below OC would result in .25125 Prism BD
Resulting in 0.945 prism vertical imbalance.
I would have the OS remade with the same prism since she likes it in the OD to see if that works.
I'm still very interested in this.
