In their recent technical paper “Comparison of modern high-speed vitrectomy systems and the advantages of using dual-bladed probes” published in the International Journal of Retina and Vitreous, January 2021, R. Oravecz et all analyze the efficiency of different vitrectomy systems and compare single with double-bladed cutters.
They examine the top four modern vitrectomy systems: EVA™ (DORC), Constellation® Vision System (ALCON), megaTRON S4HPS (Geuder) and Stellaris® PC (Bausch and Lomb), and demonstrate differences in the efficiency of vitrectomy depending on the vitrectomy system used. Their study suggests that double-bladed probes are more efficient and probably safer than single-bladed probes.
