6 months post op, experiencing lower lid retraction and hollowness. Interested in ePTFE orbital rim implant. Advice? (photo)

Hi there I have lower lid retraction following a lower bleph in the eyelid approach and a skin pinch. I am 6 months post op. My eyes feel terribly pulled down from the inside and outside. Ive read and heard lots about orbital rim implants to help the projection and to bring tissue up onto the implant by top doctors. are these implants customizable in volume? What is the least volume one would get with an orbial rim Implant when executing a retraction repair? Thank you
