    This study analyzed 250 extracapsular cataract extractions, finding a 4.8% rate of posterior capsule-zonular disruption. Prompt management prevented vitreous loss in half of these cases, allowing lens implantation in most.

    Area of Science:

    • Ophthalmology
    • Surgical Techniques
    • Cataract Surgery

    Background:

    • Posterior capsule-zonular disruption is a known complication in cataract surgery.
    • Understanding the incidence at different surgical stages is crucial for prevention.

    Purpose of the Study:

    • To determine the incidence of posterior capsule-zonular disruption during planned extracapsular cataract extraction.
    • To analyze the occurrence at each specific surgical step.

    Main Methods:

    • A consecutive series of 250 planned extracapsular cataract extractions were reviewed.
    • Complications were recorded at each stage: nucleus expression, cortical cleanup, anterior capsular flap removal, posterior capsule polishing, and lens implantation.

    Main Results:

    Related Experiment Videos

    • The overall incidence of posterior capsule-zonular disruption was 4.8%.
    • Disruptions occurred most frequently during cortical cleanup (3.2%).
    • Vitreous loss occurred in 2.4% of eyes; prompt management prevented vitreous face disruption in 50% of these cases, enabling lens implantation in 80%.

    Conclusions:

    • Posterior capsule-zonular disruption is an infrequent complication in extracapsular cataract extraction.
    • Early recognition and appropriate management are key to minimizing visual consequences and enabling successful lens implantation.
