Teeth extraction & now eye herpes..

My 3 year old cat has had bad teeth since I adopted her as a kitten from a humane society. After battling with severely infected gums & resulting malnourishment from lack of eating we had 13 of her teeth extracted last 2 Thursday's ago. She was happy and obviously pain free when we brought her home and then her eye developed a sore and she stopped
Opening it 2 days later. We took her to the vet and was prescribed duralactin, a lysine supplement, but her eye isn't really improving a week and 1 day later. She is burrowing herself and going back to her old ways pre surgery. I'm worried the bad teeth and now the eye herpes could be a sign of a bigger problem.
I would appreciate anyone's insight on this! I'm a first time poster and worried about my kitty, Popperdoodle.

Most likely the stress of the vet's visit has triggered an infection.  I'd ask the vet for an eye drop.  It can take up to a month for lysine to have any effect.  Make sure you're giving 1000mg/day divided into 2 doses.
