Summary
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.
