In ophthalmology, it is most commonly part of a trocar\u2013cannula system for vitreoretinal surgery. It helps surgeons access the back of the eye through the sclera (the white outer wall). You may hear it mentioned in the context of \u201cvitrectomy\u201d and \u201cmicroincision\u201d eye surgery."}
