CTRs, manufactured from quality blue or clear PMMA material
The Capsular Tension Rings ( CTRs ), made of Blue or Clear PMMA, assists the cataract surgeon in placing and
to center an intraocular lens, an artificial lens made of PMMA, hydrophilic / hydrophobic acrylic or silicone material,
which has to be implanted to restore the patients vision after the natural lens is removed during cataract surgery.
The CTR is manufactured in the US out of Blue or Clear PMMA and available
in five ( 5 ) different sizes from 11.00mm. to 14.00mm.

The tension rings offer high flexibility, high memory control and are easy to insert
by the ophthalmic surgeon, either manually or with any available CTR injector.
CTRs appear to be an effective device for improving the outcome of complicated
cataract surgery in eyes with zonular weakness. Implanting a CTR during the
phacoemulsification procedure may reduce:
Intra operative zonular separation
Posterior capsular rupture
Lens drop into the vitreous
Use of the CTR also increases the success rate of in-the-bag IOL implantation.
Postoperative benefits of a Capsular Tension Ring include:
Improved IOL centration
Less IOL tilt
Less capsular contraction
Less anterior and posterior capsular opacity formation
Size ( 5 ) - Available in either blue or clear PMMA
The CTR is used for patients who have weakened or missing zonules ( thin tissue fibers that hold the lens in place )
and provides additional support to the capsular bag that surrounds the eye’s lens.
