DSEK (Descemet Stripping Endothelial Keratoplasty)
DSEK is a partial thickness cornea transplant, replacing the failed inner lining (endothelial layer) of the cornea. This small incision technique selectively transplant the inner lining of the cornea, restoring sight to the patient.
DSEK involves replacing some of the defective inner layers of the cornea with healthy donated tissue. Both have a relatively small incision size when compared to traditional, full thickness, cornea transplants and offer a much lower risk of astigmatism.
DSEK provides the potential of rapid visual recovery while still maintaining the structural integrity of the patient’s eye. Frequently, two or fewer sutures are used during the entire procedure. The long-term risk to the eye with regard to rejection or injury/trauma is also much lower with this procedure than with traditional, full thickness, cornea transplants.
PTK (Photo-Therapeutic Keratectomy)
PTK goes one step beyond SK and is Dr. Parekh’s preferred treatment for corneal diseases such as RCE and EBMD . Once the defective surface cells are removed, an excimer laser is used to treat the underlying layer, so that the new, healthy replacement cells can take their place.
