DMEK vs. DSEK Corneal Transplants: What to Know

DMEK and DSEK are modern corneal transplants that replace damaged cells in the cornea. While both can improve vision affected by corneal swelling or cloudiness, they differ in several important ways.

At Eye Care Institute in Santa Rosa, CA, board-certified ophthalmologists Daniel G. Rich, MD; Nina Ni, MD; Lillian Yang, MD; Arwa Alsamarae, MD; Avni Shah, MD; Venkatesh Brahma, MD; and Madeline Ripa, MD, along with optometrist Bruce P. Abramson, OD, provide expert, compassionate eye care throughout Sonoma County.

What Are DMEK and DSEK?

DMEK and DSEK are endothelial corneal transplants that replace damaged tissue at the back of the cornea. DSEK uses donor endothelial cells with a thin layer of supporting tissue, while DMEK uses a thinner graft containing only the Descemet membrane and endothelial cells.

DMEK vs. DSEK: What Are the Main Differences?

Here’s a quick look at the key differences between DMEK and DSEK:

Feature	DMEK	DSEK
Donor Tissue	Uses a very thin graft containing Descemet membrane and endothelial cells	Uses endothelial cells, Descemet membrane, and a thin layer of supporting corneal tissue
Graft Thickness	Thinner	Slightly thicker
Visual Outcomes	Can provide excellent visual outcomes	Can provide significant vision improvement
Graft Rejection Risk	Generally lower	Slightly higher compared with DMEK
Surgical Technique	Technically demanding because the delicate graft requires careful positioning	Donor tissue can be easier for the surgeon to handle
When It May Be Used	Often considered when replacing only the damaged endothelial layer is appropriate	May be preferred in certain cases based on the condition and anatomy of the eye

Which Corneal Transplant Is Right for You?

Your eye doctor will consider your diagnosis, corneal health, eye anatomy, previous surgeries, and overall vision needs when discussing endothelial corneal transplant options. Conditions such as Fuchs’ endothelial corneal dystrophy may be treated with DMEK or DSEK, depending on the findings of your examination.
