Posteriorly dislocated capsular tension ring.

A 69-year-old man who had pseudoexfoliation and significant nuclear cataract underwent cataract surgery in his right eye. At the beginning of the phacoemulsification, inferior zonulolysis was observed and a capsular tension ring was implanted. Anterior vitrectomy was also performed because of vitreous in the anterior chamber at the end of surgery. A tear in the posterior capsule could not be identified. Three days after surgery, the capsular tension ring was observed partially in the anterior vitreous. A 3-port pars plana vitrectomy was performed and the ring was removed. Three weeks later, the eye developed retinal detachment and was successfully repaired. Retinal complications can develop if the capsular tension ring moves into the vitreous.
