    Abstract

    Purpose: To report a case of iatrogenic corneal perforation from an ejected cannula.

    Methods: Case report.

    Results: During corneal tunnel hydration following a successful phacoemulsification procedure, a hydration cannula on a Luer lock syringe was forcefully ejected into the corneal stroma. The cannula exited from the posterior aspect of the cornea and lodged in the anterior chamber angle. The post operative exam revealed an intact iris, no hyphema, and a normal fundus exam. An Oculus-Pentacam HR (high resolution) Scheimpflug scan outlined the area of stromal penetration.

    Conclusions: Previous reports advocate the use of Luer lock over slip lock syringes to avoid cannula ejection during intraocular surgery. However, the use of a Luer lock syringe did not prevent a cannula from ejecting into the cornea during wound hydration. Surgeons should therefore not assume that the use of a Luer lock syringe will prevent this occurrence, but should confirm the security of any type of cannula prior to use.
