The Capsular Tension Ring (CTR) may be inserted into the capsular bag either immediately following continuous curvilinear capsulorhexis (prior to phacoemulsification) or following cataract extraction, just before intraocular lens implantation.
At the surgeon’s discretion, the CTR may be implanted using forceps or injected with a CTR injector.
- CTR10 (10mm)
- CTR12 (12mm)
- Available in blue and clear
The size, either 10.0 mm or 12.0 mm, is selected by the surgeon according to the following guidelines:
- Corneal white-to-white measurement > 11.75 mm should use the 10mm size (uncompressed diameter of 12.15 mm)
- Corneal white-to-white measurement < 11.75 mm should use the 12mm size (uncompressed diameter of 14.4 mm)
Generally, the 10.0 mm size should be used in most eyes except those with a large capsular bag, such as in highly myopic eyes, unless the surgeon has reason to believe that the 12mm size is warranted to provide additional support.
Advantages
- 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
- Stabilized conditions during surgery
- Easy controlled insertion with specially developed micro inserter
- EO sterilized
- High flexibility & springiness
- One piece CQ PMMA ring
Indications
- Anticipated zonular dehiscence
- Lens subluxation
- Expected complications during phaco surgery
- Implantation of foldable lenses
- Situations in which sudden unfolding of a foldable IOL might cause zonular breakage or dislocation of the IOL.
- Repositioning of IOL decentration
Indications for Myopia
- High risk myopic eyes
- Myopic eye with IOL power of less than 16 diopters
