• We describe a simple procedure that facilitates the removal of a pars plana cannula. A 2-cm 4-0 black silk suture is passed under the double-throw knot, which secures the infusion cannula. When the ends of the silk suture are pulled, the double-throw knot opens easily, allowing the cannula to be removed.
