So a couple things here -
First, once you have antibodies to hsv1, it is very, very unlikely that you would ever autoinoculate (spread it to another part of your body). You've had this for a really long time, and antibodies develop within a few months, so I wouldn't worry about that at all.
The other thing is that herpes infects nerve groups. Oral herpes infects the trigeminal nerve. That nerve affects the mouth, nose and eyes. It's possible that it could, at some point, travel and cause ocular (eye) herpes, but that's not common at all, especially now that you're on the meds.
It's always a good idea to be careful when touching an outbreak and make sure you don't touch your eyes, or contacts, if you wear them, but you don't need to obsessively worry about this.
If you're in the US, and the famciclovir is expensive, you might get just as good results from acyclovir or valacyclovir, and it might be cheaper on your insurance coverage. Just an FYI.
