‘Skip-tip’ feature at the end of the ring allows the CTR to be easily guided in the capsular bag.
Ophtec has developed a unique production process for the manufacturing of CTRs: Compression Molding Technology. During the compression molding process the molecular structure of PMMA is enhanced by redistributing the molecules into longer chains, resulting in a much stronger material.
The Pre-compression shape (oval) becomes perfect circle under full compression. The circular shape keeps the capsular bag perfectly symmetrical.
An image simulation using the actual modulation transfer function of an eye with a multifocal lens (left) and one with both lens and a capsular tension ring (right) show an increase in sharpness in the latter eye.
Perfectly circular capsular bag. Ophtec tension rings are designed to be more flexible and not deform the capsular bag.
The unique feature associated with the Rinject product is the proprietary manufacturing process used to manufacture each Ringject capsular tension ring - compression moulding. 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 most other tension rings which can be brittle and can snap when inserted under stress. And we can easily control the speed and the action/retraction of the CTR injection. Also, it’s very convenient in case of deep set eyes because it has long small tip.
The RingJect is great. Being pre-loaded is the major advantage because it saves time and confusion in the OR. The leading portion of the CTR (ski-tip) helps reduce the risk of the ring catching the weak capsular bag, and the flexibility of the ring allows for a soft implantation.”
I use Ophtec CTRs regularly on my premium lens cases, CTRs allow for short and long term rotational stability for toric IOLs, and positional stability for presbyopic IOLs. Furthermore CTRs give extra assurance in the rare instance a toric IOL has to be adjusted or presbyopic IOL needs to be exchanged. For these reasons, I have never regretted a prophylacticplacement of a CTR.
I use CTRs with all of my Premium IOLs. I have tried different types of CTR, but my favorite one is the Ophtec CTR, which is easy to implant and gives the best results.
