DSEK (DESCEMET’S STRIPPING ENDOTHELIAL KERATOPLASTY)

What Is DSEK?

In DSEK, only the damaged inner layer of the cornea is removed and replaced. Your ophthalmologist transplants a thin disc of healthy donor endothelial cells along with a small amount of supportive corneal tissue (called stromal tissue). This donor tissue is carefully placed through a small incision and held in place using an air bubble. The air bubble helps the new layer adhere to your existing cornea. Only a few stitches are typically required.

Benefits of DSEK Surgery

Compared to full-thickness corneal transplants like PK (Penetrating Keratoplasty), DSEK offers several advantages:

• Faster procedure time and a smaller incision
• Quicker visual recovery since most of your own cornea is preserved
• Faster healing and lower risk of wound complications
• Lower chance of astigmatism (blurred or distorted vision due to corneal shape)
• Reduced risk of graft rejection, according to most ophthalmologists

Potential Limitations of DSEK

While DSEK has many benefits, it may not be suitable for every patient:

• It does not treat significant corneal scarring or problems in the outer layers of the cornea
• The donor tissue can shift after surgery; additional procedures or repositioning may be needed
• Patients are usually asked to lie flat on their back for 1–2 days after surgery to help the graft stay in place
• DSEK is a relatively new procedure, so long-term results over many years are still being studied
• Final vision may not be as sharp as with a full-thickness transplant if scarring or irregularities remain in the outer or middle cornea

Is DSEK Right for You?

DSEK is often recommended for patients with Fuchs’ dystrophy, bullous keratopathy, or other endothelial disorders. Your ophthalmologist will evaluate your eye condition and overall health to determine whether DSEK or another corneal transplant option is best for your needs.
