Question for those who have had a vitrectomy: was it worth it and what longterm problems?

Depends: What was the indication for the vitrectomy, the severity of the disease process, the existence of any complications from the vitrectomy, the postoperative course. Need more info to answer this question. If your retina specialist suggested it and you're not sure, then quickly get a second opinion.

Depends on Factors: Modern vitrectomy techniques allow most operations to heal in a couple of weeks. That said, no surgical outcome is guaranteed. The success of the surgery depends on the underlying disease severity, duration of disease, and skill of the surgeon. One of the common complications of vitrectomy is cataract formation or progression. Hope this helps. Good luck.
