Hopefully they will subside. You don't want a vitrectomy if you can avoid it. I had symptoms like yours about 18 years ago, turned out it was a detached retina but not super bad, was remedied by injecting a gas bubble in that eye to knit the retina back, then followed by a little laser welding to tack the retina securely. Unfortunately the treatment nucleated a cataract that I had treated last year, with excellent results. No complaints: I would always pick having my lens replaced over going blind, since time is of the essence to ensure the retina has an adequate blood supply.
Have a speedy recovery.
