    Pars plana vitrectomy can lead to cataract development. During subsequent cataract extraction, lens material was lost into the vitreous cavity in all postvitrectomy eyes.

    Area of Science:

    • Ophthalmology
    • Surgical Procedures
    • Vitreoretinal Surgery

    Background:

    • Pars plana vitrectomy is a common surgical procedure for various vitreoretinal diseases.
    • Cataract formation is a known potential complication following vitrectomy.
    • This study investigates a specific cohort of patients who underwent vitrectomy and subsequent cataract surgery.

    Observation:

    • Three patients (70-year-old male, 59-year-old female, 57-year-old female) underwent pars plana vitrectomy.
    • All three patients subsequently developed cataracts in the operated eyes.
    • Cataract extraction was performed using standard techniques, including globe massage and an ab externo incision under retrobulbar anesthesia.

    Findings:

    • In all three postvitrectomy eyes, loss of lens material into the vitreous cavity occurred during cataract extraction.

  • This suggests a potential vulnerability of the lens or surgical field after vitrectomy.
  • The conventional surgical approach may be associated with an increased risk of intraoperative complications in these eyes.

    • Implications:

    • These findings highlight a potential risk associated with cataract extraction in eyes previously treated with pars plana vitrectomy.
    • Surgeons should be aware of the increased risk of lens material loss during cataract surgery in postvitrectomy eyes.
    • Further research may be warranted to explore modified surgical techniques or preventative measures to mitigate this complication.
