It's small, but still significant enough to worry about and that's why docs generally want to avoid casually doing these surgeries unless the patient is really struggling. Here's a piece from a 2014 journal article stating the complication rates from 143 patients
"In both of these series, the reported surgical outcomes are favorable. Mason et al retrospectively reviewed 168 eyes of 143 patients undergoing PPV for symptomatic vitreous floaters. Their high surgical success rate was based on 94% of patients rating their experience as a "complete success" and 92% of patients reporting either no symptoms or extremely mild symptoms of floaters after surgery. Complications were relatively few and included 12 eyes (7.1%) with iatrogenic retinal breaks, 2 eyes with transient vitreous hemorrhage, 1 eye with cystoid macular edema, and no eyes with postoperative retinal detachment or endophthalmitis at a mean follow up of 18 months. A visually significant cataract requiring phacoemulsification developed in 9 (16.1%) of the 56 phakic eyes. The authors demonstrated a statistically significant improvement in best corrected visual acuity, which improved from a mean of 20/40 preoperatively to 20/25 postoperatively."

There's plenty of surgeons that will do it, but you might have to ask around. I've spoken to teenagers who have had the surgery done, so it's not unheard of
Yeah I know what you mean. I stopped myself from driving at the end of 2016 because the large one in my left eye nearly caused me to crash into someone while I was busy trying to "flick" it out of my central vision. Luckily I live close to uni so I don't need my car for now
Try find a pair of blue light blocking sunglasses if you can. I find them infinitely better at taking the edge off floaters. They'll usually have an orange tint
