The Morcher Capsular Tension Ring (CTR) is designed to stabilize the capsular bag during cataract surgery in eyes with zonular weakness or absence.

Manufactured from PMMA with blunt-tipped eyelets at both ends, the open-ring design distributes radial expansion force evenly across the capsular bag and zonular apparatus. This helps improve capsular stability, reduce the risk of intraoperative complications, and support optimal intraocular lens (IOL) centration.

The CTR is intended for permanent implantation within the capsular bag and may also help reduce postoperative capsular contraction (phimosis) while maintaining stable long-term positioning.

  • The Capsular Tension Ring works by distributing radial expansile force evenly throughout the capsular bag and zonular structure. This transfers tension from healthy zonules to weakened or absent areas, improving overall bag stability during cataract surgery.

  • By stabilizing the capsular bag intraoperatively, the CTR helps reduce the risk of complications associated with zonular weakness and provides improved support during lens implantation procedures.

  • The tension applied across the capsular bag helps maintain better intraocular lens centration and may reduce postoperative capsular contraction (phimosis).

  • The CTR is manufactured from PMMA and features an open-ring configuration with blunt-tipped eyelets for safe and stable long-term implantation within the capsular bag.

  • Ultrasound biomicroscopy studies have demonstrated that a properly positioned CTR remains stable between the IOL haptic and ciliary body without iris contact, supporting safe and consistent postoperative positioning.
