Piece of trash.
My specialist said this is what he wanted me to buy to protect my eye after prokera was put in my eye. He said it created a air tight seal. I it’s a piece of trash. I’d give 5 cents for it. I was robbed. I’m taking it to him to the next appointment. So he knows what’s he’s telling patients.  A joke. Not keeping air out of my eye at night.  It moved around all night. I constantly woke up trying to move it to protect my eye. It doesn’t tighten.  Crap. I’m going to return.
