Pupil capture: prevention and management.

R L Lindstrom, W K Herman

    Journal - American Intra-Ocular Implant Society
    |January 1, 1983

    Summary
    This summary is machine-generated.

    Pupil capture after posterior chamber lens implantation is uncommon. Different lens types and fixation methods show varying, low incidences, with no vision loss or significant complications reported.

    Area of Science:

    • Ophthalmology
    • Surgical Innovation

    Background:

    • Posterior chamber lens implantation is a common procedure.
    • Pupil capture is a known, albeit infrequent, complication.

    Purpose of the Study:

    • To evaluate the incidence of pupil capture with different intraocular lens (IOL) types and fixation methods.
    • To assess the visual outcomes and complications associated with pupil capture.

    Main Methods:

    • Retrospective analysis of 100 patients undergoing posterior chamber lens implantation.
    • Categorization of IOLs by haptic angulation (planar vs. angulated) and fixation (sulcus vs. capsular bag).
    • Documentation of pupil capture events, visual acuity, and complications.

    Main Results:

    • Incidence of pupil capture was 3% for sulcus-fixated planar J-loop lenses.

    Related Experiment Videos

  • Incidence was 1% for sulcus-fixated angulated J-loop lenses.
  • Incidence was 1% for capsular bag-fixated flexible Y-loop lenses.
  • No vision loss or clinically significant late complications were observed due to pupil capture.

    • Conclusions:

    • Pupil capture rates vary by IOL design and fixation.
    • Current IOLs and techniques result in low incidences of pupil capture.
    • Early noninvasive management (mydriasis, loop compression) can be effective.
