I have a patient with 1.00 cylinder level in both eyes.
which level of cylinder shall I order for the Biomedics Toric I
perscribed him: 0.75 or 1.25?
(His "K" is 7.7mm, and the lens is not too steep or too flat for the
eye)

Regards, Tom.

I would start with 0.75 cyl. using high is also possible if you think
he might really have a little more based upon your K readings.

I never prescribe a stronger cyl in a soft lens than the measured
spectacle cyl. It just seems wrong to do that (mainly because you end up
with axes in the residual that are 90 deg off from the patient's
uncorrected state. So to me the choice is obvious.
