Ophtec RingJect™ Capsular Tension Ring
A preloaded, ready-to-use Capsular Tension Ring (CTR) with a single-use injector provided in a sterile blister. The self-loading design facilitates surgeon convenience and enables clockwise or counter clockwise insertion.
Manufactured from highly flexible compression moulded polymethacrylate (PMMA), Ophtec RingJect™ is a highly-precise medical device for insertion in the capsular bag. Only Ophtec can tie its tension rings in a knot.
The pre-compression shape (oval) becomes perfect circle under full compression. The circular shape keeps the capsular bag perfectly symmetrical.
Only Ophtec has the unique “ski tip” feature. The ends of the rings gradually “tip-up” like a ski tip - this enables easy guidance of the CTR in the capsular bag as the ring is dialled-in.
The ‘ski tips’ allow the tips to flow unimpeded in the capsular bag and not become ‘snagged’.
Ophtec's proprietary CTR production process uses Compression Moulding Technology. During this compression moulding process, the molecular structure of PMMA is enhanced by redistributing the molecules into longer chains, resulting in a much stronger material.
This process provides a tension ring with total flexibility which ensures that each ring can be manipulated during surgery without the fear of snapping, unlike other tension rings which can be brittle and can snap when inserted under stress.
Capsular tension rings were developed to stabilise the capsular bag. The complex optics of PIOLs create a greater need for perfect IOL positioning and centration, which the use of a CTR may help achieve.
Perfect centration of multifocal IOLs is crucial to their optimum optical functioning and in preventing problems related to decentration and tilt, especially night-vision complaints.
