I was curious so I ran the numbers. I found a very effective technique to calculate these normally difficult effects (like change 1 eyeball with a reroll) quickly.
It assumes that if you have a focus, you use it. In regards to TLT, I haven't checked yet, but I imagine your odds can be slightly improved if you neglect to use focus on your first attack if you roll 2 blanks and a focus. That gets extra complicated because it has to take into account the defender.
