They won't remove the buckle, so you can probably forget that idea.
As far as having a vitrectomy goes.. I'd say why risk it? It's a major surgery, and you're very lucky that you still have your vision. A vitrectomy at this point is just asking for trouble, as there could be more complications from it, including another tear as well as membrane growth after the surgery.
Use the search feature and find the article I posted about vitrectomies for "floaters". Risks blindness, infection, bleeding, worse vision, retinal detachment. Of course its very risky.
