Astigmastism too bad for regular Toric lenses?

I do not have astigmatism and get to wear Acuvue 2. However, my sister
has astigmatism. Previously she would wear a soft lens that lasted her
2-3 years, but the eye doctor is now ordering for her a monthly
astigmatism lens that they claim can be worn for 3-4 months. Are some
people's astigmatism so bad that they can't wear something like Acuvue
Toric or Bausch & Lomb's Toric?

Acuvue Toric only covers more common (lower) amounts of astigmatism.

B&L torics do offer higher ranges, but nobody recommends yearly lenses anymore.
It's safer and more convenient to have lenses you can replace more frequently.
B&L torics can be purchased in multipacks. "Three-month" lenses can represent a
good breakpoint between cost and convenience.

The rate of complications is pretty astronomical when lenses are two or three
years old. A little lower at one year, much lower at 3 months. It's like Vegas -
some win, some lose.
