I would wait for the surgeon to present his plan and be ready with a lot of questions - including what other patients he's had who underwent the surgery and how much their dry eye improved (and whether the improvement continued). If you have doubts... can you go off island for an opinion from another oculoplast? It's actually an advantage for the other to be out of the area - less likelihood that the other will be pals with your current surgeon so you may get a more unbiased opinion.
I'm afraid no one here can really give you the opinion you need... not enough info and this is something surgeons have to weigh in on. Personally I will always be biased on questions like this because my phone rings practically every day with someone whose dry eye was caused by an eyelid surgery that left them with poor lid closure.
