Polyeuthorthane silicone implant

Hi everyone, I had an implant put in in April but have suffered with pain from it since then. Surgeon has recommended taking it out and having a Polyeuthorthane silicone implant put in instead as it does not create so much scar tissue. These implants were banned sometime ago but are now back in stock in Europe, not the USA. Has anyone else had one or know anthing about them please?
