Suture-guided capsular tension ring insertion to reduce risk for iatrogenic zonular damage

摘要

The capsular tension ring (CTR) is a useful device for managing a zonular dialysis. However, insertion of the CTR has potential complications. The CTR can damage zonular fibers during deployment into the capsular bag. Also, the angle and point of initial contact of the CTR with the capsular bag relative to the orientation of the dialysis must be considered to avoid damage to the zonular fibers. Adequate fill of the capsular bag with an ophthalmic viscosurgical device is important to minimize the risk for capsule entanglement with the leading eyelet of the CTR. A simple technique is described to prevent these complications. The technique can be used with both standard and modified CTRs. (C) 2015 ASCRS and ESCRS
