Hello @steven96759, Welcome to Connect. I think anyone in your position would be stressed and desperate to have your vision improved. I would be looking to find as much information as possible if it were me. There is an older discussion on the topic here:
--- Epiretinal membrane/severe vision loss after surgery: https://connect.mayoclinic.org/discussion/epiretinal-membranesevere-vision-loss-after-surgery/.

The NIH has some continuing education material on Epiretinal Membrane that reviews the evaluation and treatment of the epiretinal membrane and highlights the role of the interprofessional team in evaluating and treating patients with this condition. -- https://www.ncbi.nlm.nih.gov/books/NBK560703/

You are asking some very good questions and I would want to discuss them with your surgeon or care team to go over all of the risks involved. Here is an article that talks a little about the risks.
--- Why Surgeons Are Peeling Fewer ERMs: https://www.reviewofophthalmology.com/article/why-surgeons-are-peeling-fewer-erms.

Have they discussed the possible risks and success rates with you?
