Summary
This summary is machine-generated.

Phaco one-chop surgery offers improved efficiency and surgeon control for cataract removal. This technique requires less equivalent phaco time and power, even for dense cataracts.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Phacoemulsification is the standard for cataract removal.
  • Existing techniques like phaco-chop, stop-and-chop, and phaco-flip have limitations.
  • A hybrid technique may offer improved outcomes.

Purpose of the Study:

  • To evaluate the efficacy and safety of the phaco one-chop technique.
  • To compare phaco one-chop with its constituent techniques.
  • To assess the required phaco time and power for phaco one-chop.

Main Methods:

  • The phaco one-chop technique involves three distinct phases: embedding the phaco tip and chopping, flipping the heminucleus without rotation, and evacuating the remaining heminucleus.
  • 198 eyes with Lens Opacities Classification System III cataract grades 3 to 6 were evaluated.

Related Experiment Videos

  • Equivalent phaco time (EPT) and phaco power were measured.

    • Main Results:

    • The mean EPT was 1.9 seconds.
    • For the densest cataracts, the maximum phaco power required was 5.3%.
    • The mean overall phaco power used was 2.1%.

    Conclusions:

    • Phaco one-chop is an efficient technique for cataract surgery.
    • The method requires significantly less EPT and phaco power compared to traditional techniques.
    • Phaco one-chop enhances surgeon control, efficiency, and predictability.
