A novel, versatile cannula for vitreoretinal surgery: Bapaye aspiration scraper – Initial experience

Abstract

The induction of posterior vitreous detachment (PVD) is an important step in the successful outcome of vitreoretinal surgery for various indications. This may pose a significant challenge intraoperatively in cases of strong adhesion between the posterior hyaloid and retina. Various techniques to achieve intraoperative PVD have been described which involve active aspiration as well as non-aspiration techniques to achieve a plane of separation between the posterior hyaloid and retina. Very frequently, combinations of these techniques might be necessary to achieve successful PVD induction. We describe a novel instrument that combines aspiration as well as non-aspiration techniques for PVD induction, Bapaye aspiration scraper. It is also useful in various vitreoretinal interface procedures due to its design and is compatible with small-gauge vitrectomy systems which are commonly used in modern vitreoretinal surgery.
