Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Hard nuclei present a significant challenge in cataract surgery.
  • Current phacoemulsification methods can be time-consuming and technically demanding with dense cataracts.

Purpose of the Study:

  • To present a new phacofracture method for efficiently managing hard nuclei during cataract surgery.
  • To describe a technique that facilitates nuclear disassembly and removal.

Main Methods:

  • A central horizontal fracture divides the nucleus into two hemisections.
  • A phacoprobe creates a sinus in the inferior hemisection.
  • A chopper splits the hemisection into quadrants using the sinus.
  • The technique is replicated for the superior hemisection.

Main Results:

  • The described phacofracture method allows for controlled fragmentation of hard nuclei.
  • This technique potentially reduces phacoemulsification time and energy delivery.
  • The method provides a systematic approach to nuclear disassembly.

Conclusions:

  • This novel phacofracture technique offers a viable alternative for managing hard nuclei.
  • The method may enhance safety and efficiency in cataract surgery for dense cataracts.
