Migration of retained broken chopper tip after phacoemulsification.

We report removal of a retained broken chopper tip after phacoemulsification. Although the foreign body was thought to be stable in the ciliary sulcus 2 months postoperatively, it dislocated into the anterior chamber 8 months later. It was removed with a microforceps under gonioscopic visualization. Although previous reports suggest that retained metallic fragments after phacoemulsification can be left in place if they are difficult to access and appear stationary, our case highlights the potential for long-term instability. We therefore recommend consideration of surgical removal with the use of gonioscopic, endoscopic, or posterior segment visualization systems, as required.
