This study followed 52 large corneal grafts (over 9 mm). Most transplants remained clear with good vision after three years, despite some endothelial cell loss.

Area of Science:

  • Ophthalmology
  • Corneal Transplantation
  • Cell Biology

Context:

  • Large-diameter corneal grafts (>9 mm) present unique surgical challenges.
  • Understanding long-term outcomes is crucial for graft selection and patient care.
  • This study examines a specific cohort with distinct surgical indications.

Purpose:

  • To evaluate the long-term (3-year) outcomes of perforating corneal grafts larger than 9 mm.
  • To assess graft clarity, visual acuity, and the incidence of secondary glaucoma.
  • To investigate changes in endothelial cell density following large-graft transplantation.

Summary:

  • Follow-up of 52 patients receiving large corneal grafts (>9 mm diameter).
  • Graft clarity and final visual outcomes were generally good over a 3-year period.

  • While secondary glaucoma was not a significant issue, a notable decrease in endothelial cell density was observed.

    • Impact:

    • Provides valuable data on the efficacy and potential complications of large-diameter corneal grafts.
    • Highlights the importance of monitoring endothelial cell health in long-term graft survival.
    • Informs surgical decision-making for complex corneal cases requiring larger grafts.
