A novel foldable capsular ring system (CFCR) offers safe implantation and excellent 6-month outcomes. This new design effectively prevents complications like capsule folds and opacification in cataract surgery patients.

Area of Science:

  • Ophthalmology
  • Medical Devices
  • Surgical Innovation

Background:

  • Cataract surgery requires stable capsular bag support.
  • Existing capsular tension rings have limitations in implantation and long-term stability.
  • A need exists for improved capsular tension and bending ring systems.

Purpose of the Study:

  • To describe a new foldable capsular tension and bending ring system (CFCR).
  • To evaluate the safety and efficacy of CFCR implantation in human eyes.
  • To assess postoperative outcomes including complications and posterior capsule opacification.

Main Methods:

  • A novel foldable capsular ring system with sharp-edged segments was designed.
  • The CFCRs were implanted in 104 adult eyes after phacoemulsification via small incisions.

  • Various insertion techniques including cartridge systems and forceps were utilized.
  • Follow-up was conducted for 6 months to monitor for complications.

    • Main Results:

    • The CFCRs were successfully implanted in all 104 eyes without intraoperative complications.
    • No postoperative complications such as capsule folds or inward bending were observed during the 6-month follow-up.
    • Posterior capsule opacification was minimal or absent in all cases.

    Conclusions:

    • The new foldable capsular tension and bending ring system demonstrates safe and effective implantation.
    • The CFCR system provides excellent capsular bag stability and prevents common postoperative complications.
    • This innovative device shows promise for improving outcomes in cataract surgery.
