Clinical outcome of YAG laser vitreolysis (Ultra Q Reflex®) for the treatment of floaters

Abstract

PurposeFloaters are localized vitreous opacities that are products of vitreous degeneration or posterior vitreous detachment (PVD). Usually, observation was the only solution, however some patients are suffered from floaters. This study reports the clinical results of YAG laser vitreolysis for the treatment of floaters.MethodsThe patients with floaters were involved who visited Pureun eye hospital between January and March 2015. The patients were involved who met the following criteria; the floaters caused by localized vitreous opacities or PVD; patients suffered from floaters and strong desire for cure. The patients with diabetic retinopathy, retinal detachment, severe media opacity and young age were excluded. Patients had pre and postoperative examinations including visual acuity, tonometry, wide fundus photography, slit lamp and fundus examination. Patients were examined 1, 4 and 8 weeks after treatment. The floater scores were measured with survey paper for the evaluation of subjective change. The wide fundus photography was used for the objective change.ResultsThe 47 eyes were involved (27 cases:male and 20 cases:female). The mean age was 69.5 ± 14.3. Informed consent was obtained in all cases. The floater scores were significantly improved after treatment (preoperative: 73.6 ± 10.5, postoperative: 8.2 ± 4.6, P < 0.001). The visible floaters disappeared in 43/47 cases (91.5%) in wide fundus photography. There were no significant changes in VA and IOP. Other side effects such as retinal detachment or hemorrhage and cataract were not developed during follow up period.ConclusionsThe clinical outcome of YAG laser vitreolysis using Ultra Q Reflex showed favorable results in subjective and objective measurement. There were no significant complications after procedure. We think YAG laser vitreolysis could be the excellent treatment option for the floaters.
