If the surgical incision was made at the first axis, say between 160 and 170 degrees, the incision may have flattened the cornea at that
meridian and caused the axis to change to 10 degrees. Ask your surgeon to obtain Keratometry readings to determine the true corneal astigmatism, and repeat the refraction in a while. Also the surgeon should check to be sure the intraocular lens has not vaulted (Z syndrome), which may require a YAG laser procedure.
