FOV is an acronym for Floaters Only Vitrectomy. The procedure is a vitrectomy done for the sole purpose of removing the aggravating floaters from your field of vision and, thereby, improving your vision and life quality. Yes, the vitreous is removed (about 95 percent of it, anyway) and replaced with a saline solution. “Regular” vitrectomies are done in many other cicumstances than “floaters only.” For example, they are done for more emergent situations, like when someone has a detached retina, and the person is at risk of complete loss of sight.

Pars plana is the part of your eye where the surgeon enters the eye with ports and surgical instruments.

Of course, I am NOT a doctor and am just relating experiences the best I can. If you can, read all you can online or ask your ophthalmologist questions. I’ve had fair success (not perfect!) with FOVs and have documented those in detail in this discussion group over last 3 years. Good luck!
