Petalloid phacoemulsification offers a safe solution for emulsifying hard grade IV cataracts. This technique minimizes stress on the eye

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Hard grade IV nuclei present challenges during phacoemulsification.
  • Conventional methods can increase stress on the zonular apparatus.

Purpose of the Study:

  • To describe a novel technique, petalloid phacoemulsification, for managing hard cataracts.
  • To evaluate the safety and efficacy of this technique.

Main Methods:

  • A technique involving partial central debulking followed by sequential chopping into petal-shaped fragments.
  • Emulsification of fragment rims, central disc, and petal bases.
  • Application in twenty eyes with grade IV nuclei.

Main Results:

  • Successful and uncomplicated petalloid phacoemulsification in all twenty eyes.

  • Mean phacoemulsification time of 1.02 ± 0.06 minutes.
  • Mean endothelial cell loss of 4.2 ± 0.8%.

    • Conclusions:

    • Petalloid phacoemulsification is a safe and effective method for hard cataracts.
    • The technique reduces stress on ocular structures.
    • It is a useful alternative for challenging nuclear densities.
