    Summary

    Indocyanine green (ICG) staining aided visualization of a damaged anterior capsule during cataract surgery. ICG selectively stained the capsule, not exposed lens material, improving surgical precision.

    Area of Science:

    • Ophthalmology
    • Surgical Innovation
    • Medical Imaging

    Background:

    • Endophthalmitis following corneal perforation presents complex surgical challenges.
    • Traumatic cataracts with anterior capsule defects require careful management.
    • Visualization of the anterior capsule is crucial for safe cataract extraction.

    Observation:

    • Indocyanine green (ICG) was utilized to enhance visualization of an intact anterior capsule during cataract surgery in a patient with a history of corneal perforation and endophthalmitis.
    • The patient presented with a white traumatic cataract and an anterior capsule tear five months post-injury.
    • ICG staining was performed prior to capsulotomy to delineate the anterior capsule.

    Findings:

    • Indocyanine green (ICG) demonstrated a selective affinity for the anterior capsule, staining it clearly green.
    • Exposed cortical lens material did not stain with ICG, indicating specificity.
    • This selective staining facilitated improved visualization of the capsule margins before the capsulotomy procedure.

    Implications:

    • Indocyanine green (ICG) may be a valuable tool for visualizing compromised anterior capsules in complex cataract surgeries.
    • Selective staining properties of ICG can enhance surgical precision and potentially reduce complications.
    • Further research into ICG's utility in various anterior segment surgical scenarios is warranted.
