What are OPUS LUXE implants? Are they another name for the Sientra HSC implants or are they a different line of Sientra implants all together, and if so, what are the differences, the pros/cons, who are they best for, etc? Forgive me if this is a silly question, I haven't heard this term used by anyone yet and was curious and interested as I am leaning towards getting Sientra implants myself.
