TIA: target induced astigmatic vector, mag: magnitude,
SIA: surgically induced astigmatic vector, DV: difference vector, CI:
correction index (ideal value 1), ME: magnitude of error (ideal value 0), AE:
angle of error (ideal value 0), IOS: index of success (ideal value 0), DVNT:
difference vector, no toric - the vector that
describes the difference between the actual post-operative result and that
predicted by the Alcon calculation (i.e., the astigmatism which would have to
be induced to undo the toric IOL component), DVR: the
difference vector ratio (the ratio of DVNT magnitude to DV magnitude)
