In their interesting case report, Prenner et al1 illustratethe importance of secure connections between syringes and cannulas, especiallythose used in intraocular surgery. Serious complications can occur if thesecannulas act as flying objects. We described a patient who suffered intraoculardamage from a flying cannula that got dislodged from the syringe attachedto it.2 This happened when the surgeon wasperforming stromal hydration of the corneal wound at the end of phacoemulsification.The flying cannula caused posterior capsular rupture, vitreous loss, and vitreoushemorrhage.
