Is it safe to get lip fillers 2 weeks after cataract surgery or is there is risk of infection?

Dear chouxbabe,
I suggest you to discuss this with your injector. But generally speaking, filler injections should be safe 2 weeks after cataract surgery.

I do not see why there would be any reason you could not get lip filler 2 weeks after cataract surgery. 

I do recommend avoiding dermal fillers in any area of the face 4-6 before and after having any dental work (even routine cleaning). :-)
