I'm sure you'll be completely fine to get lasik while on imuran and remicade. Lasik is quite routine, the risk is quite limited, for what is essentially a simple outpatient surgery. When we talk about
increased surgery risks for UC patients on those meds, it is almost always major in-patient surgeries. It'd wager the surgeon is being a bit ridiculously overcautious.
Pretty much any surgeon out there will look at immunosuppressant with a little caution (biologics like remicade/humira, immunomodulators like imuran/6mp, and corticosteroids like prednisone), and they'd prefer us not to be on them if at all possible. However the reality is that many of us have surgeries while on those medications out of necessity. And we do just fine. As it's not worth upsetting a chronic health condition like UC by delaying medications just to reduce very small odds regarding surgical infections. They'll just monitor us a little more closely, tell us to let them know right away if we don't heal or see signs of an infection.
Your lasik surgeon's concern here is your increased risk of infection and slower healing due to the medications you are on. Those medications do, in fact, slow down our healing ability and increase our odds of an infection. However, like I said major inpatient surgeries are of concern and NOT simple outpatient procedures like a lasik lol.
The lasik surgeon's request seems fine enough, wait until your remicade levels are at their very lowest level, just before a regularly scheduled infusion. I think it's a bit unnecessary though. but, hey, if that makes the lasik surgeon sleep better at night and enables you to get rid of your contacts then great, a double-win
