Corneal graft survival rates were 78.8% at 2 years and 64.5% at 5 years. Key risk factors for corneal transplant failure include preoperative diagnosis, graft neovascularization, and rejection episodes.

Area of Science:

  • Ophthalmology
  • Transplantation Medicine
  • Corneal Surgery

Background:

  • Corneal transplantation is a common procedure to restore vision.
  • Understanding graft survival rates and failure predictors is crucial for patient outcomes.

Purpose of the Study:

  • To determine 2- and 5-year corneal graft survival rates.
  • To identify risk factors associated with corneal graft failure in a specific patient population.

Main Methods:

  • Retrospective chart review of 696 patients undergoing corneal transplantation.
  • Analysis of 468 eyes meeting inclusion criteria over a 7.5-year period.

Main Results:

  • Overall 2-year graft survival was 78.8%; 5-year survival was 64.5%.

  • Univariate analysis identified age, gender, glaucoma, diagnosis, procedure type, and postoperative factors as significant.
  • Multivariate analysis revealed six independent predictors of graft failure: preoperative diagnosis, neovascularization, peripheral anterior synechiae, gender, rejection episodes, and recipient age.

    • Conclusions:

    • Corneal graft failure risk varies significantly among transplant recipients.
    • Identified risk factors align with existing literature and can serve as prognostic guidelines for surgeons and patients.
