Purpose: To report our results and to evaluate the longterm effect of
capsular tension ring (CTR) insertion in eyes with large traumatic
zonular dialysis that underwent phacoemulsification with posterior
chamber (PC) intraocular lens (IOL) implantation.
Methods: This prospective study included 17 eyes of 17 consecutive
patients with cataract and large traumatic zonular dialysis (range
80-160 degrees determined pre-or intraoperatively). After insertion of a
CTR, phacoemulsification with foldable acrylic PC IOL implantation was
performed. Posterior capsule rupture, vitreous loss, best corrected
visual acuity (BCVA), intraocular pressure (IOP) in the pre- and
postoperative periods and postoperative IOL decentration were recorded.
Results: The mean follow-up period was 25.9 months (range 15-35 months).
Capsule collapse did not occur in any eye with a CTR. Postoperatively,
four eyes developed raised IOP that responded well to medical therapy.
An improvement in BCVA was observed in all eyes except one because of
co-existing fundus pathology. No IOL was found to be decentrated at the
end of the follow-up period, apart from one eye in which the PC IOL was
dislocated due to a postoperative trauma, in which an anterior chamber
IOL was implanted.
Conclusions: In cases of cataract associated with large traumatic
zonular dialysis, implanting a CTR before or during phacoemulsification
with an in-the-bag PC IOL is relatively safe technique with a high
success rate. The CTR was found to be efficient in preventing IOL
decentration in eyes with traumatic zonular deficiency.
