A novel capsular stabilization device effectively supports the lens capsule during cataract surgery, enhancing safety for patients with weak zonular support. This innovation minimizes surgical risks and improves intraoperative stability.

Area of Science:

  • Ophthalmology
  • Surgical Devices
  • Cataract Surgery

Background:

  • Weak zonular support poses challenges during cataract surgery, increasing risks of complications.
  • Existing methods for managing weak zonules may have limitations.

Purpose of the Study:

  • To introduce and evaluate a new flexible capsular stabilization device.
  • To assess the safety and efficacy of the device in suspending the lens capsule during phacoemulsification.

Main Methods:

  • A 10.0 mm flexible device made of 5-0 nylon was designed with a T-shaped end.
  • The device was inserted after capsulorhexis to hook the capsulotomy margin and stabilize the equator.
  • Phacoemulsification and aspiration were performed using the device in 12 eyes of 9 patients.

Main Results:

  • The device successfully suspended the capsule in all cases, facilitating safe phacoemulsification.
  • Posterior capsule rupture occurred in 2 out of 12 eyes.
  • No other significant postoperative complications were observed.

Conclusions:

  • The capsular stabilization device provides a stable capsule-iris complex during cataract surgery.
  • This device effectively reduces surgical risks associated with weak zonular support.
