An essential instrument to simplify the procedure…

Preloaded Capsular Tension Ring Injector

On-going surveillance of the ophthalmic market enables “O&Omdc”to develop and design highly efficient delivery systems,in line with market trends, that meet and exceed customer expectations. By using a combination of advanced Medical Grade Polymers and sophisticated, high-tech injection moulding techniques, we are able to offer innovativeand high-quality single-use Injectors to our customers.

The Inside-CTRDelivery System is intuitive and user friendly and delivers uncompromising quality, efficiency, consistency and patient safety.


  • The Inside-CTRDelivery System has been developed specifically to simplify the safe implantation of a Capsular Tension Ring in order to stabilise the capsular bag before, during and after cataract surgery.
  • The injector is equipped with a translucent guide, which allows the surgeon to visualise movement of the CTR in the cartridge funnel right up to the point of insertion.
  • The Inside-CTR, with its anti-rotation system, ensures safe and efficient insertion of the CTR with consistency and optimum results.

One bent eyelet, which reduces a possible puncturing (bulging) of the capsular bag when being dialled into the bag

Advantages of using Inside® CTR:

  • Expands and stabilises the capsular bag.
  • Distributes even pressure to all zonular fibres and prevents uneven pressure to single zonular fibres.
  • Ensures centration of the IOL, even with post-operative capsular bag shrinkage.
  • Reduces the risk of capsular bag or zonular damage during surgery.
  • Facilitates phacoemulsification, cortical aspiration and IOL implantation.
  • Replaces the need for a scleral IOL.
  • Simplifies potential IOL explantation.
  • Reduces the incidence of folds in the capsule
  • The Capsular Tension Rings have eyelets at both ends to facilitate insertion

Indications for using Inside® CTR:

  • Defective or partially missing zonules.
  • Potentially complicated surgical conditions.
  • IOLs luxation.
  • Zonuloysis.
  • Pseudoexfoliation.
  • Marchesani Syndrome.
  • Stabilises the capsule in cases of severe myopia.

Contraindications for using Inside® CTR:

  • Zonular damage extending more than 120° (4 hours) of the circumference.
  • Patients under the age of one year.
  • Chronic uveitis.
  • Progressive eye disease (diabetic retinopathy, uncontrolled glaucoma).
  • Preoperative complications prior to cataract surgery (vitreous body prolapse, haemorrhage).
  • Patients with perforated or damaged capsule.

Injector Packaging:

  • The Inside-CTR, is individually packed in a double blister, sealed with a Tyvek® lid, to ensure easy access and maintain perfect sterile conditions.

Handling the Inside® CTR:

  • Pull the Security Clip to draw the CTR into the injector cannula, and then remove the Security Clip.
  • Introduce the tip of the cannula into the capsular bag.
  • Implant the CTR into the capsular bag by carefully depressing the plunger.
  • Ensure that the CTR is correctly positioned and that the plunger is fully extended.
  • The CTR is then released from the injector by removing the injector hook from the CTR eyelet.
  • Finally, draw the hook back up into the injector before removing it from the capsular bag to avoid tissue damage.
