Abstract

PURPOSE: To determine the efficacy of tension ring on posterior capsular opacity by comparing the incidence of capsular opacity with cases undergoing intraocular lens implantation alone.
METHODS
In this study, we examined as many as 73 eyes which had undergone cataract surgery including CCC by the same surgeon from September 1998 to September 1999. In the tension ring group of 38 eyes, we inserted the tension ring prior to intraocular lens implantation, while in the silicon lens group of 35 eyes, we did not use the tension ring.
RESULTS
We compared the difference in percentage of posterior capsular opacity (PCO) between the two groups at 1 year postoperatively. The tension ring group (group 1) were associated with less PCO (0%) than silicone (11.4%) lens group (p=0.048). The visual acuity were not significantly different between the two groups (p=0.964).
CONCLUSIONS
The use of capsular tension ring is associated with significantly reduced degree of posterior capsular opacity and is thought to reduce lens epithelial cell migration onto the posterior capsule by mechanical apposition of the posterior capsule.
