I had IPL on my upper lids a number of times and the dermatologist used "metal contacts" to protect my eyes. And, just as you imagined, the contacts stuck to my eyes (Schirmer's of zero in both). The dermatologist used drops I carry in my purse and after some weird manipulations to un-do the suction, one at a time, they came out. But there were definitely some awkward moments (I was laughing because I imagined my life with permanent metal contacts).
I will say that prior to Lipiflow (I have my appointment on July 9), Herzig Eye told me:
However, as NeedMyEyes writes, I'm sure that they'll take care to make sure the experience isn't too upsetting.Please do not use any natural tears 4 hours prior to your visit, no ointments 24 hours prior to your visit, refrain from restasis for 24 hours prior to your visit and no makeup.
