Prevention of posterior capsule opacification using capsular tension ring for zonular defects in cataract surgery.
OBJECTIVE
To evaluate the incidence of secondary cataract in phacoemulsification and intraocular lens implantation using a capsular tension ring in case of zonular dehiscence.


METHODS
Phacoemulsification using a double capsular tension ring and intraocular lens implantation was done in 65 eyes with cataract and severe zonular weakness. One year after surgery capsular opacities and fibrosis were detected in a double-blind examination. The results were compared with a control group of 36 eyes that did not have a capsular tension ring but had similar surgery.


RESULTS
In the group with the capsular tension ring and implantation 7.7% of patients had moderate or severe posterior capsule opacification, compared with 36.1% in the control group.


CONCLUSIONS
Capsular tension rings may influence the formation of capsule opacification.
