Area of Science:

  • Ophthalmology
  • Biomaterials Science
  • Surgical Technology

Background:

  • The open poly(methyl methacrylate) capsular tension ring (CTR) was initially developed to address zonular defects or capsular stretching in specific cataract surgery cases.
  • Over time, the applications and designs of CTRs have expanded significantly beyond their original scope.

Purpose of the Study:

  • To review the diverse designs, evolving applications, and refined techniques associated with capsular tension rings (CTRs) in ophthalmic surgery.
  • To highlight the expanded utility of CTRs in managing various intraoperative challenges and improving patient outcomes.

Main Methods:

  • Review of literature and surgical techniques related to capsular tension rings.
  • Analysis of different CTR designs and their specific clinical applications.

Related Experiment Videos

  • Discussion of the impact of CTRs on surgical control and postoperative results.

    • Main Results:

    • Standard CTRs can be inserted to maintain capsular integrity during cataract removal, especially with pre-existing or intraoperative zonular defects.
    • Specialized CTR designs exist for scleral fixation in cases of profound zonular dialysis and for compensating iris defects.
    • CTRs serve as measurement tools for capsule dimensions and have demonstrated benefits in preventing capsular distortion and damage during complex surgeries.

    Conclusions:

    • Capsular tension rings have evolved into a versatile tool in cataract and intraocular lens surgery, addressing a wide range of complications.
    • Advanced CTR designs contribute to improved surgical precision, better visual outcomes, and potentially reduced risks of complications like capsular opacification.
