Temporary keratoprosthesis for use during pars plana vitrectomy

M B Landers, G N Foulks, D M Landers

    American Journal of Ophthalmology
    |May 1, 1981
    PubMed
    Summary

    Temporary keratoprostheses enable closed pars plana vitrectomy for eyes with abnormal corneas. This innovative approach allows for clear visualization and is followed by corneal grafting, proving successful in four cases.

    Area of Science:

    • Ophthalmology
    • Surgical Innovation

    Background:

    • Eyes with abnormal corneas present challenges for intraocular surgery.
    • Standard surgical approaches may be limited by corneal opacity or trauma.

    Observation:

    • A series of temporary keratoprostheses were developed.
    • These devices are designed for insertion into a trephined corneal opening.

    Findings:

    • The temporary keratoprostheses provide a clear and stable visual axis.
    • This facilitates closed pars plana vitrectomy.
    • The keratoprosthesis is replaced with a corneal graft immediately post-surgery.

    Implications:

    • This technique offers a viable solution for performing vitrectomy in eyes with compromised corneas.

  • Successful application in four patients suggests potential for broader clinical use.
  • The method combines temporary prosthetic support with definitive corneal transplantation.
