Abstract Details


Based on the right technique application neodymium YAG laser anterior vitreus floaters removal imperatively includes key vision quality factor and determines patient satisfaction after cataract surgery. Anterior vitreus floaters are common long term cataract surgery complication. The right technique of neodymium YAG laser application is described.


Retrospective analysis of 38 patients (46 eyes) who came in period of 12 months (January to December 2013) in Croatian urban hospital, examined by two ophthalmologists. Patients came after successful cataract surgery with intraocular lens implantation for neodymium YAG Laser treatment - posterior capsulotomy.


Anterior vitreus floaters were found at biomicroscope exam, after posterior capsulotomy by neodymium YAG laser performed. Patients were scheduled for second visit, for anterior vitreus floaters photodisruption. The right technique consists of: 8 different eye direction movements at sufficient pupil diameter size (dilated), right energy level choice, focus/defocus point (in order to protect retina, intraocular lens and deeper structures) and perpendicular laser laser beam direction on floater. Neodymium YAG laser energy levels used were of 5 to 7 mJ and total energy 35 to 74 mJ.


At biomicroscope no visible floaters in anterior vitreus with eye movements were found after photodisruption in all eyes. There were no intraoperative and postoperative complications in 6 months follow up. Likert 5 point scale (0=unsatisfied, 5=very satisfied) date determined patient satisfaction before (median score 3,5) and after procedure (median score 4,9) - symptoms completely dissapeared after photodisruption.


Role of ' the right technique application' as a key vision quality factor in neodymium-YAG laser anterior vitreus floaters removal, is extremely important impact factor in results and patient satisfaction. FINANCIAL INTEREST: NONE
