Compression molding technology means that CTRs are highly flexible. These PMMA Capsular Tension Rings are indicated for the stabilization of weakened, broken or missing zonules preventing IOL decentration after capsular shrinkage.
Capsular Tension Ring
Model 275/276The Capsular Tension Ring (CTR) is indicated for the stabilization of the capsular bag in case of defective or absent zonulae and/or to reduce the risk of luxation or decentration of an intraocular lens.
- Circular expansion and stabilization of the capsular bag
- Safe IOL centration in eyes with zonular dehiscence
- Reduced risk of capsular fibrosis
Compression molding technology
Ophtec has developed a unique production process for the manufacture of CTR: compression molding technology. The compression molding process enhances the molecular structure of PMMA by redistributing the molecules into longer chains, resulting in a much stronger material.
Other features
- Prevents IOL decentration after capsular shrinking
- Stabilized conditions during (phacoemulsification) surgery
