Replace the Damaged Inner Layer of Your Cornea

The cornea is the transparent front surface of your eye and is made up of several layers. The innermost layer, called the endothelium, consists of microscopic cells that continuously pump excess fluid out of the cornea to keep it clear. Because these cells do not regenerate, diseases such as Fuchs' endothelial dystrophy or damage from previous surgery can cause the cornea to swell, become cloudy, and reduce vision.

DSEK (Descemet's Stripping Endothelial Keratoplasty) and DMEK (Descemet Membrane Endothelial Keratoplasty) are advanced partial-thickness corneal transplant procedures that replace only the diseased endothelial layer rather than the entire cornea. By preserving healthy corneal tissue, these highly precise techniques typically promote faster visual recovery, reduce induced astigmatism, and lower the risk of certain complications compared with traditional full-thickness corneal transplantation in Palm Springs.

What Are the Benefits of DSEK + DMEK?

DSEK and DMEK are advanced forms of endothelial keratoplasty that restore corneal clarity while preserving as much of your natural eye as possible. Compared with full-thickness corneal transplantation, these procedures offer several important clinical advantages. Depending on your condition and eye anatomy, you may benefit from:

  • Selective replacement of only the diseased endothelial layer
  • Preservation of healthy corneal tissue and structural integrity
  • Faster visual recovery than traditional full-thickness corneal transplantation
  • Reduced surgically induced astigmatism
  • Lower risk of graft rejection, particularly with DMEK
  • Smaller surgical incisions and less invasive treatment
  • Improved optical quality through restoration of normal corneal function
  • Greater long-term corneal clarity and stability

Am I a Candidate for DSEK + DMEK?

If the innermost layer of your cornea is no longer functioning properly, DSEK or DMEK in Palm Springs may restore clearer vision while preserving the healthy outer layers of your cornea. These procedures are performed for carefully selected patients whose vision is limited by endothelial disease rather than problems affecting other parts of the eye. You may be a candidate if:

  • You have been diagnosed with Fuchs' endothelial dystrophy
  • You have persistent corneal swelling (corneal edema) that reduces your vision
  • You have blurry or hazy vision that is often worse upon waking and improves during the day
  • You experience glare, halos, or increased sensitivity to light caused by corneal swelling
  • You developed endothelial failure after cataract surgery or another eye procedure
  • You have painful recurrent corneal blisters (bullous keratopathy)
  • You have healthy retinal and optic nerve function capable of supporting visual improvement
  • You have sufficient corneal anatomy to support endothelial keratoplasty
  • You have no uncontrolled eye infection or severe ocular surface disease
  • You are healthy enough to undergo outpatient eye surgery

Your candidacy is determined through a comprehensive evaluation that includes a detailed eye examination, corneal imaging and thickness measurements, endothelial cell assessment, and retinal evaluation. By identifying the cause of your vision loss, our specialists can determine whether DSEK or DMEK is the most appropriate procedure for your condition and visual goals.

What Is the Difference Between DSEK & DMEK?

DSEK

DSEK replaces your damaged endothelial cells along with a thin layer of donor corneal stroma. This slightly thicker donor graft is often easier to prepare and position during surgery, making it an excellent option for many patients, including those with more complex eye anatomy or previous eye surgeries. Visual recovery is typically rapid, with excellent long-term outcomes.

DMEK

DMEK replaces only the diseased Descemet membrane and endothelial cells, creating an ultra-thin graft that closely matches your eye's natural anatomy. Because no additional stromal tissue is transplanted, DMEK often provides sharper vision and faster visual rehabilitation. However, it requires greater surgical precision and is not appropriate for every eye.

Your Complete DSEK + DMEK Experience

Consultation

Your evaluation begins with a comprehensive eye examination to confirm that endothelial dysfunction is responsible for your vision changes. We perform corneal pachymetry, endothelial cell analysis, corneal tomography, and optical coherence tomography when appropriate. Your surgeon also evaluates your lens, retina, and overall ocular health to determine whether DSEK or DMEK is the most suitable approach for your goals.

Procedure

Your surgery is performed on an outpatient basis using local anesthesia with light sedation. After removing the diseased endothelial layer, your surgeon inserts a carefully prepared donor graft through a small corneal incision. An air or gas bubble is then placed inside your eye to gently press the graft into position while it naturally adheres.

Recovery

After surgery, you will spend several hours lying on your back so the air bubble keeps the donor tissue securely attached. Vision is initially blurred while the bubble gradually absorbs. You will use prescription eye drops, avoid strenuous activity, and attend scheduled follow-up visits to monitor graft attachment, healing, and corneal clarity.

Results

As your new endothelial cells begin pumping excess fluid from your cornea, swelling resolves, and vision gradually improves over the following weeks and months. Most patients experience significantly clearer vision, although recovery varies depending on the severity of their disease, the procedure performed, and the overall health of their eye.

DSEK + DMEK Frequently Asked Questions

Will I receive a full corneal transplant?

No. DSEK and DMEK are partial-thickness corneal transplant procedures that replace only the damaged endothelial layer. By preserving the healthy outer layers of your cornea, these surgeries are less invasive than full-thickness transplantation and allow for faster recovery.

How long does it take to recover?

Your recovery depends on whether you undergo DSEK or DMEK and how your eye heals. While the donor graft begins functioning soon after surgery, your vision typically improves gradually over several weeks to months as corneal swelling resolves and the transplanted endothelial cells restore normal fluid balance.

What are the risks of DSEK and DMEK?

As with any eye surgery, there are potential risks, including graft detachment, infection, elevated eye pressure, graft rejection, bleeding, and incomplete visual improvement. Fortunately, these procedures have excellent success rates when performed by experienced corneal surgeons, and most complications can be managed when identified early through routine follow-up care.

Will I need to lie flat after surgery?

Yes. Following surgery, you will usually spend several hours lying on your back so the air or gas bubble inside your eye can hold the donor tissue against your cornea while it naturally adheres. Your surgeon will provide detailed positioning instructions based on your specific procedure.
