Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Retinal Surgery

Background:

  • Phacoemulsification is a common cataract surgery technique.
  • Retained nuclear fragments can occur during the transition to new surgical methods.
  • Prompt removal of retained nuclei is crucial to prevent complications.

Observation:

  • Three patients required pars plana vitrectomy due to retained nuclei post-phacoemulsification.
  • A posterior segment phacofragmenter was used to emulsify and remove nuclear fragments.
  • Sulcus intraocular lens implantation was performed after nuclear fragment removal.

Findings:

  • Pars plana vitrectomy successfully removed retained nuclei in all three cases.
  • One patient developed cystoid macular edema, and another experienced choroidal detachment.

  • Final visual acuity ranged from 20/60 to 20/30, indicating favorable outcomes.

    • Implications:

    • Pars plana vitrectomy is a viable option for managing retained nuclei after cataract surgery.
    • Early surgical intervention can lead to good visual recovery.
    • Careful technique and management are essential during the learning curve of new surgical procedures.
