Prevention of Posterior Capsule Opacification Using Capsular Tension Ring for Zonular Defects in Cataract Surgery

Abstract

Purpose 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.
