About Cornea Transplants
Corneal transplants are needed when a patient’s cornea is diseased or injured. The patient’s cornea will be replaced with a donated cornea. There are several types of corneal transplants. Your surgeon will decide which surgery is best suited for you. Listed below is an overview of the different procedures available for corneal transplants.
Penetrating Keratoplasty (PKP) is a full thickness graft transplant. Full thickness means transplanting all layers of the cornea. This is the traditional corneal transplant. Recovery time is one year and longer.
Endothelial Keratoplasty (EK) is a partial thickness graft transplant. The posterior portion of the cornea such as the descemet’s membrane and endothelium are transplanted. There are different surgery types for EK such as, Descemet Stripping Automated Endothelial Keratoplasty (DSAEK), Descemet Stripping Endothelial Keratoplasty (DSEK), and Descemet’s Membrane Endothelial Keratoplasty (DMEK). EK surgery provides faster recovery time and higher rates of transplant success.
Anterior Lamellar Keratoplasty
Anterior Lamellar Keratoplasty (ALK) is a partial thickness transplant. The anterior portion of the cornea such as the epithelium and stroma are transplanted.
