[Anatomical repercussion on the zonular apparatus after a capsular tension ring insertion in swine eyes].
OBJECTIVE
To carry out an experimental and descriptive study that exhibits the anatomical repercussions on the zonular apparatus after a capsular tension ring (CTR) is inserted.


METHODS
CTRs were inserted in five swine eyes (four with forceps, one with an injector). Two additional eyes were left untouched for control purposes. The integrity of the suspensory ligament was examined by scanning electron microscopy.


RESULTS
We did not observe alterations in the integrity of the zonular apparatus. The suspensory ligaments adopted a new fold configuration.


CONCLUSIONS
CTR insertion is a safe therapeutic tool to maintain the integrity of the lens zonules in elastic, large diameter capsular bags.
