Is astigmatism treatable by AK?

Single or paired incisions?

Location of first incision:

Length of first incision (FemtoAK):

Location of second incision:

Length of second incision (FemtoAK):

Single arcuates greater than 45 degress in length may result in irregular astigmatism. This arcuate has been truncated and may not correct the full magnitude of staigmatism. Consider disabling phaco incision, creating paired arcuate and manually creating the main wound.

Astigmatism must be > 0.5 D if ATR or oblique, > 1.0 D if WTR
Nomogram is optimized for 80% depth, 9 mm diameter
Nomogram is optimized for penetrating AKs without opening incisions
