DSEK Explained: Advanced Stitch-Free Approach to Corneal Transplants

As the clear front window of the eye which is supported by an inner pump layer breaks down, vision may present with cloudiness, fog or a washed out appearance. In which case we see that DSEK surgery is put forth as a treatment by doctors, a modern corneal transplant that is limited to the damaged inner layer and does not change the whole cornea. DSEK stands for Descemet Stripping Endothelial Keratoplasty and is what we see brought up when the topic of DSEK comes up in eye care for issues of corneal swelling.

A corneal transplant involves putting in healthy donor tissue to replace diseased tissue. The National Eye Institute reports that if only a section of the cornea is affected by damage they may do a partial thickness transplant which is also to be called lamellar keratoplasty. This is what DSEK surgery is based on which in turn is to restore corneal clarity at the same time preserving the stronger outer layers of the cornea.

What Is DSEK Surgery?

DSEK surgery is a corneal transplant we use mostly for endothelial disease. The endothelium which is the inner most layer of the cornea is what is in charge of pumping out extra fluid to keep the cornea clear. When this layer fails to function properly fluid builds up, the cornea goes hazy and vision deteriorates.

The DSEK full form which details the technique well. “Descemet stripping” is the removal of the diseased Descemet membrane and endothelial layer. “Endothelial keratoplasty” is the use of a thin donor layer which has healthy endothelial cells and putting it in the eye. NIH/NCBI medical literature reports that in endothelial keratoplastic procedure the weak endothelial layer is removed and a circular graft from the donor inner cornea is put in to improve corneal clarity.

Why Is DSEK Called a Stitch-Free Corneal Transplant?

In traditional full thickness corneal transplant surgery many sutures are required which is a result of us replacing the entire central cornea. In DSEK surgery we put in the donor tissue through a small opening and it is placed against the back surface of the patient’s cornea. Also we use an air or gas bubble to hold the graft in place as it naturally attaches.


This is what we see in DSEK which is a stitch free or nearly stitch free approach. We do not see the use of large circular sutures as in Penetrating Corneal Transplant. But by “stitch free” we must see past what is typical. Some patients may still require a small incision closure as a part of the procedure based on their eye issue and the surgeons’ choice. What we can say is DSEK surgery is more of a minimally invasive procedure as compared to a full thickness corneal transplant in which it is suited.

Conditions Where DSEK May Be Recommended

Doctors may recommend DSEK surgery when the back layer of the cornea is affected but the front and middle layers are doing well. It is a common treatment in conditions like Fuchs’ endothelial dystrophy, pseudophakic bullous keratopathy post cataract surgery, corneal edema, and certain failed graft cases. In DSEK’s full form what you get is a procedure that targets the endothelial layer and not the whole cornea which is what makes it useful for patients.

At Vasan Eye Care we do corneal evaluation which includes tests like corneal topography, anterior segment OCT, specular microscopy, and pachymetry to determine the corneal shape, layers, endothelial cell health, and thickness. Also we provide advanced corneal services at Vasan Eye Care which include corneal ulcer treatment, corneal transplant evaluation and other eye treatments which are managed by specialists.

Corneal ConcernWhat It MeansHow DSEK May Help
Fuchs’ endothelial dystrophyThe corneal pump cells gradually weakendsek surgery may replace the weak inner layer
Bullous keratopathyCorneal swelling may occur after surgery or endothelial damageEndothelial transplant may improve clarity
Corneal edemaFluid collects inside the cornea and causes hazy visionDonor endothelial cells may reduce swelling
Failed previous graftA past transplant may lose endothelial functionA specialist may assess repeat transplant options

How DSEK Surgery Is Performed

Before DSEK surgery the eye is evaluated in great detail. We check vision, corneal depth, health of the endothelial cells, eye pressure, lens health, and retina health. The donor tissue is prepared very carefully so that the healthy endothelial layer may be put in its proper place.

In DSEK surgery what we do is remove the affected Descemet membrane and endothelial cells from the back of the cornea. We then put in a donor endothelial graft which we gently cause to unfold. We put in an air bubble to hold the graft in place against the patient’s cornea. Also at times we ask the patient to lie in a certain position for a while to get the best adherence of the graft.

The dsek full form may sound technical, but the concept is simple for patients. We take the cloudy pump layer out and put in a healthy donor layer. Also because the outer cornea is left as is this approach we may see faster healing, better wound recovery and less surface distortion in which full corneal transplant is the usual treatment.

DSEK vs Traditional Corneal Transplant

MedlinePlus reports that a corneal transplant which puts in donor tissue is one of the more common transplant procedures we do for serious corneal disease. In full thickness transplant surgery the entire cornea depth is replaced. In DSEK surgery only the inner diseased layer is replaced which is the reason many surgeons prefer it for endothelial problems when the rest of the cornea is healthy.

Point of DifferenceDSEKTraditional Full-Thickness Corneal Transplant
Tissue replacedInner endothelial layerFull thickness of the cornea
StitchesUsually stitch-free or minimal stitchMultiple sutures are usually required
HealingOften faster for suitable patientsUsually longer healing period
Eye strengthOuter cornea remains mostly intactFull corneal wound needs more time to stabilize
Best suited forEndothelial failure and corneal edemaDeep scarring, severe thinning, or full corneal damage

Recovery After DSEK Surgery

Recovery from DSEK surgery is a slow process. Some patients report improved vision in weeks’ time, others do which may be a few months’ which is based on corneal swelling, how the graft is attaching, eye pressure, and your over eye health. At follow up visits which are very important the doctor will check that the graft has properly attached and that the cornea is healing as it should.

Eye drops which are typical after DSEK surgery to reduce inflammation and to also put down the risk of rejection and infection. Also patients should stay away from eye rubbing, heavy lifting, swimming, dusty settings, and missing medication. In the case of sudden pain, redness, light sensitivity, or vision drop off the patient should report to the eye specialist hospital right away.

Benefits of DSEK in Eye Care

The primary benefit of DSEK in eye care is that it addresses the affected layer of the eye instead of the whole cornea. For the right patient DSEK surgery provides a more stable visual outcome, reduced issues related to stitches, and a smoother corneal surface. Also because there are fewer large sutures used we may see less irregular astigmatism as compared to older transplant methods.


Another benefit of dsek in eye treatment is that it protects healthy corneal tissue as much as possible. This layer by layer approach is in large part what has made endothelial keratoplasty a key element of contemporary corneal care. It is also true that patients should know which is that a transplant requires for it to be done well proper pre screen, donor tissue, surgical skill, and long term follow up.

Risks and Limitations

In the like manner as with any eye surgery this transplant has its risks. We may see the graft come off which may require repositioning. There may be an issue with infection, bleeding, eye pressure changes, graft rejection, or delayed visual recovery. Also some patients may require a second go at the air bubble thing if the graft does not take. These risks are what put forth the idea that patients should not look at DSEK in eye treatment only in terms of cost or convenience.


This procedure is not for cases which have very deep scarring, severe thinning, an active infection, large scale irregularity or in the case of advanced disease in other parts of the eye. In which of those cases the cornea specialist will put forth another transplant option or will first address the base condition. For example, active infection may first need urgent corneal ulcer treatment before any transplant decision is made.

Why Choose Vasan Eye Care for Corneal Evaluation?


Choosing the right center is key to success in this process which requires for accurate diagnosis, proper tissue care, surgical accuracy and also regular follow up. At Vasan Eye Care we do corneal assessment, provide advanced diagnostic support and we have access to a large variety of eye treatments for many eye conditions. A patient looking for dsek in eye guidance should first undergo a complete consultation to confirm whether the endothelial layer is the real cause of cloudy vision.

At an experienced eye specialist hospital, the doctor can explain the dsek full form, they will go over treatment options and they will guide patients on what to expect post op. We do more than just perform the transplant, we aim to identify and put forward the safest procedure for that individual eye.

Frequently Asked Questions

The dsek full form is Descemet Stripping Endothelial Keratoplasty which which reports that the procedure removes the affected Descemet membrane and endothelial layer and in turn puts in healthy donor tissue.

DSEK in eye treatment is a procedure which involves replacement of the weak inner pump layer of the cornea which in turn allows for excess fluid to be removed and vision to improve. It is mainly used for endothelial corneal disease.

DSEK surgery is what is known as stitch free which is a misnomer some use for the fact that it does not require the large circular stitches used in full corneal transplants. In some cases a small incision may need closure.

Vision outcomes post DSEK surgery are variable between patients. Many patients see improvement over weeks to months’ time which depends on graft adherence, corneal clarity, and other ocular health issues..

A suitable candidate for dsek in eye care usually has endothelial failure with a relatively healthy outer cornea.A cornea specialist will confirm this after performing scans and a detailed eye exam.

DSEK surgery is a better option for some cases of endothelial disease as it only replaces the affected inner layer. For the full thickness scarring, very thin corneas, or complete thickness damage a full corneal transplant may still be required.

Knowing of the DSEK full form is important for patients to understand that the treatment is at a layer level. Also the DSEK full form makes it easy to talk about the procedure, recovery, and options with the cornea specialist.
