How To Treat Eye Itchiness And Irritation Post Eye Surgery?

I had a surgery10 days ago. Left eye-detached retina (injected gas bubble and sewn in a buckle) Right eye-indirect laser. Im allergic to codiene and toridol is hard on my stomach. I was a daily pot smoker previous to surgery,but haven't had any since because I was paranoid that it may cause some complications either with the healing process or creating dry itchy eyes as an irritant..so my question is is it safe again to smoke weed or perhaps use a vaporizer?if not right now then approximately when?
