A Cloudy Cornea
Can Be Made Clear. Partially.
Partial corneal transplants replace only the diseased inner layer rather than the whole cornea. Dr. DeBry was the first surgeon in Las Vegas to perform DSEK, and brought DMEK to the city in 2016.
- DMEK transplants tissue one tenth the thickness of a human hair
- Typical DMEK recovery of four to six weeks instead of a year
- The longest experience with these procedures of any local surgeon
Am I a Candidate for Cornea Transplant Surgery?
Fuchs’ dystrophy is the most common reason patients end up here. It is a fairly common degenerative condition in which endothelial cells degenerate slowly over years, first producing a slight haziness and eventually swelling the cornea outright. Surgery is recommended once visual symptoms start interfering with daily activities. Corneal edema from previous eye surgery is the other frequent path to a partial transplant.

What Is a Partial Corneal Transplant?
The cornea is the front window of the eye, like a windshield, and remarkably the body produces it perfectly clear. It has three layers. The epithelium is the thin outer skin. The stroma is the thickest part, though still only half a millimeter, and gives the cornea its strength. The endothelium is the thin inner lining, and its job is pumping fluid out of the stroma. When those endothelial cells are damaged by degeneration or previous eye surgery and lose their ability to pump, the cornea swells, turns white and cloudy, and vision fogs. A partial transplant replaces just that failing inner layer with healthy donor cells.
Patient Reviews
DMEK, DSEK, or a Full Transplant?
DMEK
Exact replacement of the diseased inner lining
- An exact anatomical replacement of the diseased tissue
- Better visual results and a better chance of reaching 20/20
- Faster visual recovery than DSEK
- A lower rejection rate
- Transplanted tissue is only 10 microns thick
- A technically demanding procedure requiring specific surgical experience
DSEK
The original partial transplant technique
- Much quicker recovery than a full transplant
- No large incisions that weaken the cornea
- The cornea keeps a nicely round shape
- Effective for corneal diseases causing endothelial cell loss and swelling
- Thicker donor tissue than DMEK
- Somewhat lower chance of reaching 20/20 than DMEK
Full Transplant (PKP)
Penetrating keratoplasty, used for decades
- The right operation when thick stromal scars are present
- Decades of use restoring vision
- Prolonged visual recovery, usually 12 months or more
- The eye is permanently weaker where the incisions were made
- Risk of severe vision loss from mild eye trauma afterward
DMEK is not automatically the answer. If there are thick scars in the stroma, a full corneal transplant is probably necessary, because replacing the inner lining alone will not clear scarred tissue.
Your Cornea Transplant Surgery Journey
- Examination of all three corneal layers
- Assessment of endothelial cell function and corneal swelling
- Determination of whether scarring requires a full transplant
- Discussion of DMEK versus DSEK for your cornea
- Donor tissue arranged through the eye bank
- The diseased endothelial layer is removed
- Healthy donor endothelial cells are transplanted in its place
- DMEK tissue is 10 microns thick, DSEK somewhat thicker
- A gas bubble is placed to hold the new cells in position
- No large incisions are made, so the cornea is not weakened
- The transplanted cells attach to the inner cornea
- Positioning instructions help the gas bubble do its job
- The cornea begins pumping fluid out and clearing
- Corneal shape stays nicely round rather than becoming irregular
- Follow-up visits track cell attachment and clarity
- Typical recovery runs four to six weeks
- Far faster than the 12 months or more a full transplant requires
- A better chance of reaching 20/20 with DMEK than with DSEK
- A lower rejection rate than full-thickness transplants
- Long-term monitoring of graft health continues
Expected Cornea Transplant Surgery Outcomes & Recovery
What Patients Can Expect in the First 30 Days
- A gas bubble is placed in the eye to hold the new cells in position
- Follow positioning instructions carefully while the graft attaches
- Typical recovery runs four to six weeks
- Vision clears gradually as the cornea pumps fluid out and regains clarity
- Attend all follow-up visits so graft health can be monitored
- Graft health is monitored at follow-up visits over the long term
Safety & Risk Considerations
Safety Profile
- DMEK patients typically experience faster recovery, better vision, and fewer surgical risks than with older techniques
- No large incisions are made, so the cornea is not left weakened
- A lower rejection rate than DSEK, and both lower than full-thickness transplant
- Dr. DeBry was the first surgeon in Las Vegas to perform DSEK and has treated hundreds of patients over the last decade
- For a series of years he was the number one utilizer of corneal tissue from the Nevada Donor Network Eye Bank
Possible Side Effects
- Transplant rejection remains possible, though the rate is lower with DMEK than with DSEK or a full transplant
- A gas bubble inside the eye requires following positioning instructions while the new cells attach
- Vision clears gradually over four to six weeks rather than immediately
- If thick corneal scarring is present, a partial transplant will not clear it and a full transplant may still be needed
How We Minimize Risk
The Longest Local Experience
Dr. DeBry performed the first DSEK in Las Vegas and brought DMEK to the city in 2016, giving him the longest experience with these procedures of any local surgeon.
Matching Procedure to Pathology
Partial transplants are used for endothelial disease and swelling. Where thick stromal scars exist, we recommend a full transplant rather than a procedure that cannot address the problem.
Established Tissue Supply
A long working relationship with the Nevada Donor Network Eye Bank, where this practice was for years the leading user of corneal tissue in the state.

locationsFrequently Asked Questions
What is DMEK?
Descemet’s Membrane Endothelial Keratoplasty, a partial corneal transplant. Descemet’s Membrane is the thin inner lining of the cornea, and it holds the endothelial cells that keep the cornea clear. In DMEK the damaged cells are removed and healthy donor cells transplanted in their place.
How is DMEK different from DSEK?
They are very similar procedures, but DMEK transplants tissue only 10 microns thick, one tenth the width of a human hair. That thinner tissue means faster recovery, a better chance at 20/20 vision, and a lower rejection rate.
Why not just have a full corneal transplant?
Full transplants have restored vision for decades, but they have real weaknesses. Best vision takes 12 months or more, the eye stays permanently weaker where the incisions were made, leaving a risk of severe vision loss from mild trauma, and sutures often leave the cornea irregularly shaped.
What is Fuchs’ dystrophy?
A fairly common degenerative condition where the endothelial cells lining the inner cornea slowly degenerate. Those cells pump fluid out of the cornea to keep it clear. As they fail, vision hazes and eventually the cornea swells. DSEK or DMEK replaces the failing cells with healthy ones. To learn more, see the MedlinePlus article on Fuchs’ dystrophy or the Cornea Research Foundation’s overview.
How long is recovery?
Typically four to six weeks for DMEK, compared with 12 months or more for a full-thickness transplant. DSEK is also much quicker than a full transplant, with a somewhat longer visual recovery than DMEK. A gas bubble is placed in the eye to hold the new cells in position while they attach.
Where does the tissue come from?
The transplant is provided as a gift from an eye donor who recently died. Our practice has worked with the Nevada Donor Network Eye Bank for years, and for a stretch was its single largest user of corneal tissue.
