Detachment of a hydrodissection cannula during a phacoemulsification procedure appeared to produce no adverse sequelae during surgery. Day 1 postoperatively, two nonpenetrating hemorrhagic retinal lesions were identified; there was no evidence of posterior capsular perforation. Day 6 postoperatively, the pupil was temporally peaked by a fine vitreous strand running to the main-port incision in the superotemporal cornea. This was divided with Nd:YAG laser, and argon laser was applied to encircle the two retinal lesions. Postoperative uncorrected visual acuity remained 6/4 at day 1, day 6, and week 4 (3 weeks after laser application) follow-up visits. Surgeons must accept responsibility for confirming the integrity of the cannula and syringe connection before beginning hydrodissection, which can be highly destructive to intracameral structures.
