DSEK Corneal Transplant Surgery
Understanding DSEK
This section explains how the inner corneal layer works and why replacing it can improve sight.
The endothelium is a single layer of pump cells that keeps the cornea clear by moving fluid out of the tissue. When these cells fail, the cornea swells and vision becomes cloudy.
DSEK removes the diseased endothelium and a thin slice of adjacent tissue, then replaces it with healthy donor cells. Only a small incision is needed, which protects the rest of the eye.
Replacing only the malfunctioning layer preserves over 90 percent of the cornea, speeds recovery, and keeps the natural shape of the eye.
Benefits of DSEK
DSEK offers several advantages over a full-thickness transplant.
The incision is small, similar to that used in cataract surgery, leading to less trauma and quicker healing.
Most patients notice clearer vision within weeks rather than the many months often needed after a traditional transplant.
Because most of the cornea stays intact, the eye remains stronger and more resistant to injury.
Limited tissue manipulation means fewer activity limits and a quicker return to daily life.
The absence of extensive sutures helps keep the natural curve of the cornea, lowering the chance of inducing astigmatism.
Using only the posterior donor layer allows the remaining tissue to help another patient and also reduces the chance of immune rejection.
Candidacy for DSEK
Not every patient with corneal problems needs DSEK. Here are the key factors.
Persistent morning blur, halos, glare, and eye discomfort suggest the endothelium is no longer working well.
This inherited disease gradually damages pump cells and is a common reason for DSEK.
Corneal swelling that follows cataract surgery or lens removal can be treated with DSEK.
A failed graft can often be replaced with a new DSEK layer.
If only the inner layer is affected and the outer layers are clear, DSEK is an excellent option.
Some conditions make other surgeries a better choice.
- Significant corneal scarring or surface irregularities
- Uncontrolled glaucoma requiring high steroid use
- Active severe dry eye or other ocular surface disease
Corneal Conditions Treated by DSEK
DSEK targets diseases that harm the posterior corneal layers.
Gradual loss of endothelial cells causes swelling and vision loss.
Post-surgical corneal edema leads to painful blisters and blurred vision.
A nonfunctioning transplant can be replaced with a new endothelial layer.
This rare inherited disorder clouds the cornea from birth and can respond well to DSEK.
Scars that affect only the inner layers can be removed and replaced through DSEK.
Diagnosis and Consultation
A detailed eye exam helps decide if DSEK is right for you.
Your symptoms, family history, and past eye surgeries guide further testing.
This microscope lets the doctor view each corneal layer for swelling or scars.
High-resolution images show endothelial cell density and health.
Measuring corneal thickness reveals the extent of fluid buildup.
Optical coherence tomography provides cross-section images to confirm graft attachment and monitor healing.
Symptoms of Corneal Endothelial Dysfunction
Recognizing these signs can prompt timely treatment.
Swelling scatters light and makes images look hazy.
Vision may improve during the day as fluid slowly leaves the cornea.
Colors fade, and details are harder to see in low light.
Bright lights can be painful, and night driving becomes difficult.
Swollen tissue may feel sore or irritated.
The eye can feel as though something is stuck on its surface.
DSEK versus DMEK
Two modern transplant methods replace damaged endothelial cells.
DMEK transplants only the Descemet membrane and endothelium, which may give even faster vision but is technically harder. DSEK includes a thin layer of stromal tissue, making the graft sturdier and the surgery more predictable.
DSEK balances safety, reliability, and visual outcome for many patients and is available from a wider range of surgeons.
The Surgical Process
DSEK is an outpatient procedure that usually takes a little more than an hour.
Numbing drops and mild sedation keep you comfortable throughout the surgery.
The surgeon removes the damaged endothelium through an incision about 2.5 to 5 millimeters wide.
A thin disc of donor tissue containing healthy pump cells is folded and placed inside the eye.
An air bubble presses the graft against the back of the cornea so it can stick firmly.
The bubble position is checked, and you receive instructions for the first day of recovery.
Recovery and Post-Operative Care
Proper aftercare is vital for a clear and lasting result.
Staying on your back helps the air bubble keep the graft in place.
Antibiotic and steroid drops prevent infection and rejection. Follow the schedule exactly.
Several early visits allow the team to confirm graft attachment and check eye pressure.
Most people see better within a week and reach stable vision by three months.
Possible issues include graft dislocation, rejection, or pressure spikes, but these are usually manageable with timely care.
Effectiveness and Long-Term Outcomes
DSEK has an excellent track record for restoring sight.
Studies show that most grafts remain clear for many years, with many patients reaching 20/40 vision or better.
Even after a decade, the majority of grafts continue to function well and provide stable vision.
Episodes of rejection or graft failure occur in a minority of cases and can often be treated successfully.
Some cell loss is expected over time, yet vision typically remains sharp because the remaining cells keep the cornea clear.
Frequently Asked Questions
Here are answers to common questions we hear from patients considering DSEK.
The cornea specialist reviews your medical history, measures corneal thickness, and checks cell counts to decide if early surgery will give the best results.
Yes. When performed by an experienced surgeon, DSEK is a safe and effective way to treat endothelial failure.
Most patients notice improvement within days, and full recovery usually occurs in three to four months.
No. The small incision is self-sealing, so stitches are rarely necessary.
Rejection can happen but is less common than with full-thickness grafts and is often controlled with steroid drops.
You may resume light activities soon, but follow all postoperative instructions to protect the graft.

Patient at Westwood Ophthalmology for almost 10 years. Dr. Pagan is my ophthalmologist, she is wonderful. I saw Dr. Lee recently for cornea surgery and follow-up. He is competent and caring.
Beth Cruz
excellent surgeon . very satisfied with cornea transplant.
Greg
They did a very thorough analysis and found I had a scratched cornea. This will be my new go to for optometry.
Paula Clark
Dr. Pagan is an excellent doctor and even better human being.
Allen Lowenstein
Dr. Lee performed surgery on both my eyes. My vision is perfect. Dr Lee is the best.
