Vitreous prolapse during cataract surgery is a complication caused by zonular or capsular rupture. Risk factors include forceful capsulotomy and issues during nucleus delivery, impacting intraocular lens implantation.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Cataract Surgery

Context:

  • Extracapsular cataract extraction with intraocular lens (IOL) implantation is a common surgical procedure.
  • Vitreous prolapse is a recognized complication that can arise during this procedure.

Purpose:

  • To identify the causes and risk factors associated with vitreous prolapse during extracapsular cataract extraction and IOL implantation.
  • To analyze clinical data from 427 cases (458 eyes) to understand malpractical complications.

Summary:

  • Vitreous prolapse, resulting from zonular and posterior capsular disruption, was identified as a malpractical complication in 458 eyes undergoing cataract surgery.
  • Common causes of zonular disruption include overly large or deep capsulotomy and uneven irrigating pressure.

  • Risk factors for posterior capsular rupture and vitreous prolapse encompass obstructed passage, difficult nuclear delivery, and issues with anterior chamber maintenance and IOL insertion.

    • Impact:

    • Understanding these factors can help surgeons mitigate risks and improve patient outcomes in cataract surgery.
    • Highlights the importance of precise surgical technique to prevent complications like vitreous prolapse.
