Cannula-associated Ocular Injuries during Cataract Surgery: A Preventable Intraoperative Complication?

Although rare, inadvertently dislodged cannula can occur during cataract surgery. We report two cases of cannula-associated ocular injury during stromal hydration of the main corneal incision despite the use of Luer-lock syringes. Case 1 suffered from an initially occult intraocular injury which led to a delayed presentation of vitreous prolapsing into the anterior chamber, presumed posterior capsular rupture, vitreous hemorrhage, and multiple retinal tears, which required a three-port pars plana vitrectomy and cryotherapy.

Lens dislocation following trauma sustained 40 years ago during cataract surgery pre-assessment.

Background: To report a case of spontaneous lens dislocation following pupillary dilatation during preoperative assessment for cataract surgery.

Methods: Our patient had been punched on the left side of the face 40 years ago but throughout this period the patient's vision had remained normal and ophthalmic evaluation by opticians had also been normal on multiple visits. He was referred to our clinic for cataract assessment.
