Summary
This study on the triple procedure for corneal transplantation found an 82.1% transparency cure rate. Endothelial cell density significantly decreased post-surgery, with factors like rejection impacting outcomes.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Cell Biology
Context:
- Corneal transplantation is crucial for vision restoration.
- The triple procedure combines penetrating keratoplasty, extracapsular excision, and intraocular lens (IOL) insertion.
- Understanding long-term endothelial changes is vital for surgical success.
Purpose:
- To evaluate time-related changes in corneal endothelial cell density after a triple procedure.
- To assess the transparency cure rate and complication incidence.
- To identify factors influencing endothelial cell loss.
Summary:
- The triple procedure demonstrated an 82.1% transparency cure rate over a mean follow-up of 53.4 months.
- Endothelial cell density decreased by 60.6% at 5 years post-operation.
- Factors such as punching method, IOL optical zone diameter, and rejection influenced early cell density reduction.
Impact:
- The triple procedure is a viable surgical option for specific corneal conditions.
- Findings highlight the importance of monitoring endothelial cell health post-transplantation.
- Identifying risk factors can guide surgical technique and patient selection for improved outcomes.
