Outcomes of pars plana vitrectomy for visually significant floaters in Northern Alberta

The current study supports PPV as an effective treatment option for symptomatic floaters. There was no statistically significant difference between preoperative and postoperative visual acuity. However, 29.9% of eyes underwent floaterectomy in the contralateral eye, which is in support of patient satisfaction. The observed complication rate was 7.3%, with retinal detachment being the most common complication. Of the 410 eyes, 30 eyes (7.3%) had postoperative complications which included adverse events that were recorded to have occurred between the immediate postoperative period and three years after vitrectomy. Complications include retinal detachment (2.4%), elevated IOP (1.5%), clinically significant cataract requiring surgery (1.5%), vitreous hemorrhage (0.73%), cystoid macular edema (0.98%), dislocated IOL (0.24%), endophthalmitis (0.24%) and epiretinal membrane (0.24). There was a statistically significant difference in visual acuity between preoperative and postoperative periods for eyes with complications.
