Hello. I am in the STEPS research study on Spheramine and due for surgery in June. Could you direct me to some pwp who have been through the surgery and wouldn't mind sharing their thoughts and experiences? I apologize in advance for any lapses in protocol - this is high-tech to me and I am more than a little nervous. I finally got the courage to write...(hey this wasn't too scary...)! Thank you . redbirdwillfly
