As far as I know, there's no credible evidence that a macular pucker (aka epiretinal membrane, epimacular membrane) disappears on its own. Most cases don't affect vision much, so they don't require surgery. How much vision is restored by surgery depends on a number of factors, including the surgeon's skills and the presence/absence of macular edema.
One of the very best vitreoretinal surgeons is Dr. Steve Charles of Memphis, Tennessee. There is more information about macular puckers on his website. You can contact him through his website, and he will respond personally to your specific concerns. There is also a good article about epimacular membranes on emedicine.
Dear Jack886,
I would recommend that you ask your eyeMD these questions. A retinal specialist who performs this surgery is better able to assist you.
