This study introduces a novel technique for cataract surgery, using a modified cystitome to measure and create an adequate continuous curvilinear capsulorhexis (CCC) for stable intraocular lens placement.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Achieving an adequate continuous curvilinear capsulorhexis (CCC) is crucial for stable intraocular lens (IOL) implantation during phacoemulsification.
  • Inconsistent capsulorhexis size can lead to postoperative complications and suboptimal visual outcomes.

Purpose of the Study:

  • To present a novel, simple intraoperative method for accurately measuring and creating a continuous curvilinear capsulorhexis (CCC) of adequate size.
  • To enhance the precision and reliability of capsulorhexis creation in phacoemulsification.

Main Methods:

  • A novel technique utilizing a dented cystitome as a measuring guide for capsulorhexis creation.
  • A dent is created on a cystitome using tenotomy scissors at 2.5 mm, serving as a guide for a 5 mm CCC.

Main Results:

  • The dented cystitome reliably guides the creation of a continuous curvilinear capsulorhexis (CCC) of approximately 5 mm diameter.
  • This technique facilitates a well-centered and stable intraocular lens with complete anterior capsular overlap postoperatively.

Conclusions:

  • The dented cystitome technique offers a reliable and consistent method for achieving adequate capsulorhexis size in phacoemulsification.
  • This approach benefits both novice and experienced surgeons, improving surgical outcomes and patient vision.
