BIO VISION CTR

Dependable, Reliable, Safe & Uniform

We manufacture Capsular Tension Rings in clear as well as Blue PMMA CQ UV, Polymethylmethacrylate (PMMA). Capsular Tension Rings enhance the safety and efficacy during phacoemulsification and posterior chamber Intraocular lens implantation. They also prevent vitreous herniation and maintain the circular contour of the capsular bag. CTR’s also tend to reduce Intraocular lens decentration, which improves vision and gives additional support to the IOL. They may also inhibit epithelial cell proliferation, thus reducing the chances of capsule opacification.

BENEFITS

Circular expansion and stabilization of the periphery of the capsular bag

Reduced risk of capsular fibrosis and shrinking

Safe IOL centration in eyes with zonular dehiscence

Prevents vitreous herniation from weak zonular area

TECHNICAL SPECIFICATIONS

Capsular Tension Rings are available in three models CTR 11, CTR 12 and CTR 13.
