I agree with Luvtoski, but they were probably referring to Posterior Capsular Opacity. This is the clear membrane which surrounds the IOL implant. It occasionally will turn cloudy and need a simple, quick, painless, cool laser to permanently remove it...done in the office.

If they are referring to a "epiretinal membrane" with the scar tissue, as far as I know the only real fix is a Vitrectomy to remove it.
A vitrectomy is serious surgery (I had one done 3 yrs ago) so you wouldn't want to do it unless the scar tissue affects your central vision, or impairs your vision so much that you can't stand it.
Go to a Retina specialist, or two or three for opinions and OCT tests which
show your retina and the scar tissue. Have them clearly explain your options.
