I have a patient with the follong RX:
OD: -3.50 +1.00 x 180
OS: -1.00 +1.50 x 180
SV lenses
I have had plenty of patients in my day do just fine with a RX with 3 diopters difference, but this patient has seen "double" with every pair of glasses he has from other opticals. In the interest of getting it right, I would like to get some opinions about what may help him.
He says when he looks straight through the lens it is "okay", but if he tilts his head up or down he sees two of everything he focuses on (i know, i know ... "well, stop doing that!") My first instinct is was that the BCs were too different for comfort, but his current pair has the correct RX with 4B lenses both. He has tried a SV slab off already ... whatever help that was supposed to be? Anyone seen this before? Would an aspheric design help? I am at a loss. Thanks.
