This study introduces a novel surgical technique using a temporary keratoprosthesis for eyes with corneal opacity and vitreoretinal disorders. This approach successfully restored vision in 90% of previously untreatable cases.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Retinal Surgery

Context:

  • Vitreoretinal disorders often present challenges for surgical visualization due to corneal opacity.
  • Traditional methods may fail in complex cases, leaving patients with limited options for sight restoration.

Purpose:

  • To present a new surgical technique combining temporary keratoprosthesis with pars plana vitrectomy for simultaneous treatment of corneal and vitreoretinal issues.
  • To evaluate the efficacy of this combined approach in saving sight in previously untreatable eyes.

Summary:

  • A temporary keratoprosthesis is inserted into a trephined corneal opening to enable clear visualization for pars plana vitrectomy.
  • Following vitrectomy, the keratoprosthesis is replaced with a corneal graft, addressing both corneal opacity and underlying vitreoretinal pathology.

  • The procedure was performed on 10 patients, with 9 achieving satisfactory visual outcomes, including one with maintained acuity of 0.3 after 15 months.

    • Impact:

    • This innovative one-stage surgical procedure offers a new method for rehabilitating sight in patients with severe, combined corneal and vitreoretinal disorders.
    • The technique proved effective in saving eyes previously considered unsalvageable by other treatments.
    • Successful integration with other vitreoretinal procedures, like retinal detachment repair, highlights its versatility.
