Alternative technique for insertion of Eva Dorc® infusion cannula in vitreoretinal surgeries

Técnica alternativa de inserção da canula de infusão do Eva Dorc® em cirurgias vitreorretinianas

Abstract

This paper provides a fast and inexpensive technique to prevent slippage of the infusion cannula from the EVA DORC® 27-gauge system. After the usual retrobulbar anesthesia, antisepsis and asepsis, a 2% hydroxypropyl methylcellulose drop is placed around the infusion cannula in the trocar to hold it in position. This technique prevents the slippage of the infusion cannula and both the surgical time and creation of the first sclerotomy in the eye can be shortened slightly.
