A new modified chopping technique allows surgeons to break apart soft nuclei before using phacoemulsification. This method reduces the energy and power needed during cataract surgery, improving efficiency and patient outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Traditional chopping techniques aim to minimize phacoemulsification power during lens removal.
  • Soft nuclei present challenges for conventional chopping, often necessitating energy-intensive methods like sculpting.

Purpose of the Study:

  • To introduce a modified chopping technique for soft nuclei.
  • To reduce phacoemulsification power and energy consumption in cataract surgery.

Main Methods:

  • A modified chopping technique was developed to mechanically cleave soft nuclei.
  • The technique prepares the nucleus into fragments prior to phacoemulsification.

Main Results:

  • The modified technique effectively fragments soft nuclei.

  • Reduced total phacoemulsification power and energy expenditure were observed.

    • Conclusions:

    • The modified chopping technique offers an efficient alternative for soft nucleus removal.
    • This approach can decrease the energy load on the eye during cataract surgery.
