Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Radial tears at the capsulorhexis edge complicate nucleus extraction.
  • Maintaining capsular integrity is crucial for successful intraocular lens implantation.

Purpose of the Study:

  • To introduce and evaluate a new nucleus extraction technique, "double-hook extraction."
  • To prevent radial tears during extracapsular cataract extraction.

Main Methods:

  • The double-hook extraction technique involves three steps: fluid dissection, double-hook extraction, and nucleus removal.
  • This technique is performed during planned extracapsular cataract extraction.

Main Results:

  • The double-hook extraction technique effectively prevents radial tears at the capsulorhexis edge.
  • It ensures complete in-the-bag posterior chamber lens implantation.

Conclusions:

  • Double-hook extraction is an easy, safe, and effective method for nucleus extraction.
  • This technique preserves capsular integrity, improving outcomes in cataract surgery.
