Zonular dialysis and vitreous loss with a J-shaped hydrodissection cannula during phacoemulsification.

We report a complication that occurred during clear corneal phacoemulsification. When saline was injected during hydrodissection with a 27-gauge J-shaped cannula attached to a 2.0 mL luer-lock polypropylene syringe, the cannula dislodged and slipped behind the iris, hooking to the lens equator. Although the cannula was carefully removed, 3 clock hours of zonular dialysis were observed between the 4 o'clock and 7 o'clock meridians. After phacoemulsification, lens aspiration, and in-the-bag intraocular lens implantation, vitreous was noted inferiorly and the anterior vitrectomy was completed.
