Penetrating Keratoplasty (PK)
Penetrating Keratoplasty (PK) is a procedure in which damaged, diseased, or scarred cornea is replaced with a healthy cornea from a deceased human donor. Cornea transplants can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. Because the cornea is an avascular tissue, corneal transplants do not require the same host/graft matching process as required in organ transplantation. Although most cornea transplant procedures are successful, the procedure does have a small risk of complications, such as rejection of the donor cornea.
Intralase Enabled Keratoplasty (IEK)
Intralase Enabled Keratoplasty (IEK) is a novel approach to corneal transplant surgery. The IEK procedure uses the Intralase Excimer laser to create incisions in the donor and recipient tissue. This method allows for exceptional precision; the better the fit between the old cornea and new cornea, the better the chances of less post-operative astigmatism and a faster recovery.
Descemet’s Stripping Endothelial Keratoplasty (DSEK)
DSEK is one of the latest techniques in corneal transplantation designed specifically for patients with damage to the endothelium of the cornea (innermost layer). It is a partial-thickness corneal transplant that replaces only the diseased endothelial layer, and replaces it with new endothelial tissue from a healthy donor. This surgical technique is a significant improvement over the standard corneal transplantation operation because it takes less time, involves a smaller surgical incision, requires far fewer stitches, heals faster, and has a faster visual recovery.
