Floaters

Hi, at the beginning of this year I was investigated for glaucoma and underwent 2 day long investigations..I was recommended to redo this investigation in a year. Recently I realized that I must have at least one floater, maybe I had it before but now that I'm more attentive, I observe it. Do you think that investigations which suppose contact with the eyeball can cause or is related to floaters ? What is your experience with floaters.
