Surgically induced astigmatism Calculator (SIA) has been programmed to calculate, by vector analysis, the amount of surgically induced astigmatism created during the cataract surgery.

Just introduce keratometry data (prior and post surgery) and the corneal astigmatism axis, and it shows the surgical induced astigmatism.

Incision data management is only for annotation purpose.
