PURPOSE Explantation of a dislocated capsular tension ring (CTR) from the vitreous cavity can be challenging, typically requiring a bimanual hand-shake technique or cutting the CTR into segments. We present 3 cases of dislocated intraocular lens (IOL)-CTR-capsule complexes in which CTRs were explanted efficiently and safely by employing a CTR inserter (CTR-I) through a clear corneal incision. METHODS Retrospective case series. RESULTS CTRs were successfully explanted by freeing the eyelet of the CTR from the capsule, engaging it with the CTR-I hook and retracting the CTR into the device's shaft while maintaining the entire IOL-CTR-capsule complex in a safe position behind the iris plane. No complications of the procedure were observed in all 3 cases. All patients had subsequent uneventful IOL exchange via sutureless scleral fixation during the same surgery. CONCLUSION The CTR inserter provides a simple and efficient approach to CTR removal from IOL-CTR-capsule complexes dislocated into the vitreous cavity. Greater awareness of this technique among providers is needed.
