Abstract Details


To investigate the clinical safety and efficacy of Nd: YAG laser vitreolysis vsvitrectomy in patients with a prolonged history of floaters resulting in posterior vitreous detachment.


Rivierenland Hospital, Tiel, the Netherlands


A retrospective analysis of 100 eyes with a 9-month, or longer, history of floaters secondary to posterior vitreous detachment. Thirty-five eyes were treated with pars plans vitrectomy, while 65 eyes were treated with YAG laser vitreolysis. In the laser vitreolysis group, the treatment was performed using a Q-switched, Nd:YAG laser.


The average age of the patients was 55. There was a slightly lower rate of self-reported postoperative visual improvement among patients treated with the YAG laser than in those treated with vitrectomy, at respective rates of 80% and 90%.


The results support the use of YAG laser vitreolysis for floater removal among patients with a history of floaters that are secondary to posterior vitreous detachment and persist for at least 9 months. Over a 10-year follow-up period, safety of the procedure was indicated by the absence of any complications among YAG-treated patients.
