Loop-on-suture-guided insertion for easier capsular tension ring insertion and easier residual cortex removal
2020
Abstract
The capsular tension ring (CTR) is a useful aid in cataract surgery involving zonular impairment. In standard implantation with tweezers or injectors there is limited control of the leading eyelet, and this can cause excessive stress on the zonular fibers and lead to damage of the capsular bag.
Several techniques have been investigated with the aim of reducing these risks. Herein, a simple new modification of the suture-guided CTR technique is described.
Adding a loop to the suture can facilitate manipulation during implantation and during the removal of cortex residues at the end of cataract extraction.
