Endothelial Keratoplasty
What Is Endothelial Keratoplasty?
Endothelial keratoplasty is a corneal transplantation technique that selectively replaces only the innermost layer of the cornea, called the endothelium, rather than transplanting the entire cornea as older techniques required.1
Fuchs endothelial corneal dystrophy is the most frequent indication for this type of corneal transplantation, with additional common indications including pseudophakic bullous keratopathy and failure of a previous corneal graft.2
Two primary approaches are used today, Descemet membrane endothelial keratoplasty and Descemet stripping endothelial keratoplasty, each differing in the specific layers of tissue transplanted.1
In Descemet membrane endothelial keratoplasty, only the endothelium and Descemet membrane are transplanted, providing superior outcomes compared to Descemet stripping endothelial keratoplasty.

How Does Endothelial Keratoplasty Work?
Descemet membrane endothelial keratoplasty involves selective removal of the patient’s own defective Descemet membrane and endothelium, which is then replaced with healthy donor tissue containing only these same two thin layers, without any additional stromal tissue.3
During the procedure, an air or gas bubble is used to gently press the new donor tissue against the back of the patient’s existing cornea, allowing it to attach and begin functioning without the need for sutures in most cases.4
This targeted, layer specific approach represents a significant advancement over traditional full thickness corneal transplantation, minimizing the amount of tissue that needs to be replaced.1
Who Benefits From Endothelial Keratoplasty?
Patients with Fuchs endothelial corneal dystrophy, a condition in which the corneal endothelium gradually fails, represent one of the primary groups who benefit from this targeted procedure.2
Patients with pseudophakic bullous keratopathy, a complication that can occur following cataract surgery, and those with a previously failed corneal graft may also be appropriate candidates for endothelial keratoplasty.2
A preoperative visual acuity worse than twenty over forty is generally considered an appropriate threshold for surgical intervention, with earlier surgery increasingly favored to achieve better visual outcomes at one year.2
The Treatment Approach
Surgical decision making for endothelial keratoplasty is based on a combination of visual acuity testing, central corneal thickness measurement, and corneal densitometry evaluation.2
Descemet membrane endothelial keratoplasty and Descemet stripping endothelial keratoplasty both provide meaningfully faster visual recovery compared to traditional full thickness corneal transplantation.2
Research shows the median time to achieve best corrected visual acuity of at least twenty over forty was approximately seven point eight months for Descemet membrane endothelial keratoplasty, compared to nearly thirty eight months for traditional penetrating keratoplasty.2
Risks and Considerations
Both Descemet membrane endothelial keratoplasty and Descemet stripping endothelial keratoplasty require temporarily raised intraocular pressure to properly attach the donor graft, which can potentially worsen preexisting glaucoma or contribute to new onset glaucoma.4
Graft rejection remains an important risk consideration following endothelial keratoplasty, and ongoing research continues to identify specific risk factors that increase the likelihood of this complication occurring.5
Additional potential complications can include graft detachment, requiring careful patient positioning after surgery to support proper healing and attachment of the new donor tissue.6
Outcomes and Effectiveness
Descemet membrane endothelial keratoplasty has evolved into a routine surgical procedure for posterior lamellar keratoplasty, reflecting its established safety and effectiveness across large numbers of patients treated worldwide.3
Ten year outcome data comparing Descemet membrane endothelial keratoplasty, Descemet stripping automated endothelial keratoplasty, and traditional penetrating keratoplasty provide valuable long term insight into graft survival and endothelial cell density loss over time.7
Overall, large retrospective case series involving hundreds of consecutive patients have demonstrated consistently favorable clinical outcomes following Descemet membrane endothelial keratoplasty.6
Why Visual Communication Matters for Endothelial Keratoplasty
Explaining how surgeons selectively transplant an extremely thin layer of corneal tissue requires visuals that make this precise, technically demanding procedure understandable to patients and clinical audiences alike.
Pharmaceutical companies, ophthalmology practices, and medical device manufacturers rely on precise illustration and animation to explain endothelial keratoplasty technique and outcomes.
- Illustrating corneal layer anatomy and the tissue targeted for replacement
- Animating the donor tissue preparation and insertion process
- Explaining the role of the air or gas bubble in graft attachment
- Visualizing differences between DMEK and DSEK surgical techniques
- Supporting patient education on recovery and positioning requirements
- Creating training materials for corneal surgery clinicians

Frequently Asked Questions
What is endothelial keratoplasty?
It is a corneal transplant technique that replaces only the innermost endothelial layer of the cornea rather than the entire cornea.1
What conditions is endothelial keratoplasty used to treat?
Fuchs endothelial corneal dystrophy and pseudophakic bullous keratopathy are among the most common indications.2
What is the difference between DMEK and DSEK?
DMEK transplants only the endothelium and Descemet membrane, while DSEK includes a thin layer of additional stromal tissue.1
How quickly do patients recover vision after this procedure?
Recovery is significantly faster than traditional corneal transplantation, with many patients reaching good visual acuity within several months.2
What are the main risks of endothelial keratoplasty?
Elevated eye pressure, graft rejection, and graft detachment are among the key risks to consider.4
Is endothelial keratoplasty considered a routine procedure?
Yes, particularly DMEK, which has become a well established, routine approach to posterior corneal transplantation.3
