particle image velocimetry (PIV); vitrectomy; vitreous cutter


Vitreous cutters are surgical devices used during vitrectomy to remove the vitreous humor from the eye and replace it with tamponade fluids. The aim of the present work is to assess the performance of the EVA Phaco-vitrectomy System vitreous cutter (Dutch Ophthalmic Research Center (DORC) BV; Zuidland, The Netherlands) used with diff erent needle sizes and blade shapes. The analysis is based on laboratory measurements of fluid flow performed using the particle image velocimetry (PIV) technique.
