Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Anterior continuous curvilinear capsulorhexis (CCC) is a critical step in cataract surgery.
  • Current techniques may carry risks of inadvertent tearing or complications, especially in challenging cases.

Purpose of the Study:

  • To describe a novel anterior continuous curvilinear capsulorhexis (CCC) technique utilizing a dull needle.
  • To evaluate the safety, efficacy, and advantages of this technique.

Main Methods:

  • A dull needle with a blunt tip and rough surface is employed for CCC.
  • The technique allows for controlled tear propagation with adjustable power vectors.
  • An arcade-shaped CCC is preferred over a circular CCC for biomechanical advantages.

Main Results:

  • The dull needle prevents inadvertent anterior capsule tearing.
  • The technique enables safe, controlled, single-step capsulorhexis.
  • Surgical time is reduced compared to conventional methods.
  • The technique is effective even in cases with white and liquefied cortex.

Conclusions:

  • The described dull needle CCC technique offers a safe, controlled, and efficient alternative for cataract surgery.
  • This method simplifies the capsulorhexis procedure, reducing complications and surgical duration.
  • It is a valuable tool for surgeons, particularly in complex cataract cases.
