Results of Vitreous Floaters Treatment Using a Yag-Laser Device with a Coaxial Light Splitter

Abstract

Purpose: to evaluate the efficiency of vitreous floaters removal using the Nd: YAG-laser DIXION LPULSA SYL-9000 with a coaxial light splitter. Patients and Methods. The study involved 24 patients (24 eyes) with Weiss ring-type floating vitreous opacities. All patients underwent laser vitreolysis on a Nd: YAG-laser DIXION LPULSA SYL-9000 with a coaxial light splitter. Laser procedures were performed at OPTIMED Laser Recovery Center. The age of the patients was from 47 to 81 years (average 58.3 ± 8.9 years). Among the patients 15 (62.5 %) were women and 9 (37.5 %) — men. Before procedure, a complete ophthalmological examination including registration of best corrected visual acuity (BCVA), autorefractometry, pneumotonometry, biomicroscopy, fundus examination, ultrasonic biometry, ultrasound B-scan was performed. Statistical processing was performed using Statistica v.10.0.0 (StatSoft®, Inc.) and Excel (Microsoft Office Professional 2016) software. The patients were observed for three months before the procedure. Follow-up examination was performed one day after the procedure. Results. After laser vitreolysis procedure all patients had a subjective vision quality improvement. In 18 (75 %) patients, floating “flies” completely disappeared. The remaining patients noted the disappearance of a large floating spot. Conclusion. The laser vitreolysis on the Nd: YAG-laser with a coaxial light splitter allows to improve the quality and visual acuity in patients with vitreous floater. The obtained results demonstrated that Nd: YAG-laser DIXION LPULSA SYL-9000 is effective and could be recommended for treatment of symptomatic vitreous floaters.
