Using a Capsular Tension Ring (CTR) Inserter for CTR Explantation in Cases of Posteriorly Dislocated Intraocular Lens-CTR-Capsule Complex.

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 three cases of dislocated intraocular lens (IOL)-CTR-capsule complexes in which CTRs were explanted efficiently and safely by using a CTR inserter (CTR-I) through a clear corneal incision.

METHODS

Retrospective case series.

RESULTS

Capsular tension rings 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 three cases. All patients had subsequent uneventful IOL exchange through 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.
