I'm not an optometrist, but I play one on TV. Seriously though, I've worked in an eye doctor's office for three years, and our doctors would ask you a few questions prior to fitting you with one type of lens over another.
1. Do you have any problems with dryness with your current conventional lenses?
2. Do you want to sleep in your contacts, i.e, be fit with an extended wear contact lens?
3. Are you myopic or hyperopic/nearsighted or farsighted?
4. How many hours per day do you typically wear your contacts?
5. How much time, if any, do you spend on a computer each day?
At my office, our doctor prefers Encore Toric (made by Cooper Vision) as a two week lens, and the Frequency 55 Toric as a monthly lens. I'm fairly sure that Encore can be wore as an extended wear lens, but I'd have to check Tyler's Quarterly to be sure. For the most part, the vision out of Lens Type A will be similar to Lens Type B, but one lens is usually more comfortable than the other.
Edited to add that most patients with astigmatism do see better with their glasses versus their contacts because the lenses of the glasses stay in the same position, while the contacts do not stay in the same position on the eye.
