Laser Vitreolysis of Symptomatic Vitreous Floaters. Report 1. Retrospective Analysis

Purpose : To perform a retrospective study and evaluate patient satisfaction rates and the incidence of complications associated with YAG laser vitreolysis for symptomatic Weiss ring floaters, comparing early and delayed intervention timing following posterior vitreous detachment (PVD). Methods . A retrospective analysis of laser vitreolysis (LV) was conducted over the period from August 2016 to December 2024 (400 weeks) using outpatient records of 966 patients (1187 eyes, 1532 treatment sessions). Two study groups were identified based on the time from appearance of Weiss ring symptomatic floaters (SF): Group I (early vitreolysis) — 309 patients (355 eyes), treated within 3 months with complete PVD. Laser vitreolysis was performed using the Ultra Q Reflex laser system (Ellex Medical Lasers, Australia). Results : Retrospective studies of early and delayed vitreolysis showed high patient satisfaction rates (93.8% and 91.6%, respectively) and low incidence of laser vitreolysis complications (0.2% and 0.4%, respectively). Conclusion . YAG laser vitreolysis is a safe and effective method for treating symptomatic vitreous floaters with high patient satisfaction rates. Early vitreolysis of Weiss ring symptomatic floaters with complete PVD is the treatment of choice for laser therapy.
