Vitrectomy for cloudy vitreous and floaters

I have been very nearsighted most of my life, had clear lense replacement surgery 2 years ago which went very well and improved my vision. But, for many years I have had cloudy vitreous and floating globs that obscure my vision, making driving, reading, and other activities very challenging. A retina specialist told me I should have a vitrectomy, but I'm concerned about long-term side effects such as glaucoma, dry eye, etc. should I be concerned about these at all? I'd really like to know others' experiences with vitrectomy. As much as I trust my doctor, I really would like others' thoughts on vitrectomy. Seeing like this makes just about everything very difficult. Thank you.
