S-DMEK in Egypt: First Surgeon — Dr. Ahmed Shaarawy, cornea.clinic Cairo

A Medical Milestone: Dr. Ahmed Shaarawy, founder of cornea.clinic and established corneal transplant surgeon in Cairo, has become the first surgeon in Egypt and the Arab world to successfully perform S-DMEK (Suture-assisted Descemet Membrane Endothelial Keratoplasty). This advanced technique expands the possibilities for patients with corneal endothelial disease who were previously considered unsuitable candidates for standard DMEK surgery.

What Is S-DMEK and Why It Matters

Descemet Membrane Endothelial Keratoplasty (DMEK) has become the gold standard for treating corneal endothelial diseases over the past 15 years. However, standard DMEK has limitations. It requires a minimum endothelial cell count, careful patient selection, and technical precision during insertion and positioning. For patients with low endothelial reserves, previous failed grafts, or anatomically complex corneas, traditional DMEK was simply not an option.

S-DMEK—suture-assisted DMEK—changes this calculus. By incorporating temporary sutures to anchor and position the donor tissue, surgeons can now safely perform DMEK in cases that would otherwise require older, less ideal transplant techniques (such as PK—penetrating keratoplasty, or DSEK—Descemet Stripping Endothelial Keratoplasty).

The clinical benefits are significant:

• Lower endothelial cell thresholds: Patients with marginal endothelial cell counts can now be treated with the superior outcomes of DMEK rather than requiring penetrating keratoplasty.
• Improved graft retention: Temporary sutures provide mechanical stability during the critical early healing phase, reducing the risk of graft dislocation—particularly important in cases with challenging anterior chamber anatomy.
• Broader candidacy: Patients with anterior chamber lenses, keratoconus, or post-surgical corneal scarring are now viable candidates.
• Faster visual recovery: Like standard DMEK, vision improves rapidly once the graft adheres and clears.
• Lower rejection rates: DMEK's inherent advantage—minimal foreign surface antigen exposure—remains intact with S-DMEK.

S-DMEK vs. Standard DMEK: The Key Differences

While standard DMEK relies on the patient's eye pressure and careful anterior chamber manipulation to position the donor tissue, S-DMEK uses temporary sutures (typically 3–5 interrupted 10-0 nylon sutures placed through the limbus) to anchor the graft during insertion and healing. The sutures are removed after 2–4 weeks, once the graft has adhered naturally.

Feature	Standard DMEK	S-DMEK
Graft positioning	IOP and AC pressure	Temporary limbal sutures
Typical endothelial count requirement	~2,200–2,500 cells/mm²	~1,800+ cells/mm² (variable)
Graft dislocation risk (early phase)	5–15% per published series	Reduced with suture stabilization
Suture removal needed	No	Yes, after 2–4 weeks
Best for difficult cases	Limited utility	Ideal solution

The temporary sutures make S-DMEK a bridge technique—combining the speed and clarity of DMEK with the mechanical control of suture-based methods. Once epithelialization and wound healing begin, the sutures can be safely removed, and the patient benefits from a fully suture-free cornea, which means minimal astigmatism induction and excellent long-term visual quality.

Dr. Ahmed Shaarawy: Training Path to Innovation

Dr. Ahmed Shaarawy's journey to becoming Egypt's first S-DMEK surgeon is grounded in rigorous international training and a commitment to bringing world-class corneal surgery to the Arab world.

Fellowship at Devers Eye Institute (Oregon, USA, 2014)

In 2014, Dr. Shaarawy completed an advanced fellowship in corneal and anterior segment surgery at the Devers Eye Institute in Portland, Oregon—one of North America's premier centers for keratoplasty. Devers is recognized as a leading center where DMEK techniques are taught, refined, and advanced. Under expert mentorship, Dr. Shaarawy mastered the full spectrum of DMEK, from graft preparation and insertion techniques to troubleshooting and management of complications.

This training provided the foundational expertise necessary to advance beyond standard DMEK into specialized variations like S-DMEK. The Devers experience exposed Dr. Shaarawy to emerging innovations in corneal transplantation and an evidence-based approach to expanding surgical candidacy.

Return to Cairo: Establishing cornea.clinic

After his fellowship, Dr. Shaarawy returned to Cairo and established cornea.clinic, a dedicated corneal and anterior segment surgery practice. From the beginning, the clinic has maintained international standards for patient care, surgical technique, and donor tissue management.

Over the past decade, cornea.clinic has treated hundreds of patients with corneal endothelial disease, building a track record of excellent surgical outcomes. The infrastructure—including precise surgical equipment, trained nursing staff, and a structured approach to graft acquisition and preparation—created the ideal foundation for introducing S-DMEK.

Founder of ESK-CT: Building Egypt's Corneal Transplant Community

Beyond individual surgical innovation, Dr. Shaarawy has worked to strengthen corneal transplantation as a specialty across Egypt. He founded the Egyptian Society for Keratoplasty and Corneal Transplantation (ESK-CT), an organization dedicated to:

• Advancing surgical standards and training for corneal surgeons in Egypt and the Arab region.
• Promoting evidence-based protocols for donor tissue procurement, evaluation, and transplantation.
• Fostering collaboration among ophthalmologists and establishing a registry of corneal transplant outcomes.
• Educating patients and the public about corneal disease and the benefits of transplantation.

The founding of ESK-CT signals Dr. Shaarawy's broader vision: transforming Egypt into a recognized hub for advanced corneal surgery, reducing the need for Egyptians to travel abroad for specialized treatment.

Why S-DMEK Is a Game-Changer for Difficult Cases

In Egypt and across the Arab world, corneal endothelial disease affects thousands of patients. Causes include:

• Fuchs' endothelial dystrophy (genetic, progressive)
• Post-cataract surgery corneal edema (pseudophakic bullous keratopathy)
• Anterior chamber IOL complications
• Chemical and thermal burns (trauma-related)
• Previous failed corneal grafts

Before S-DMEK, many of these patients faced limited choices:

• Penetrating keratoplasty (PK): A full-thickness graft that requires sutures for 12–24 months, carries higher rejection rates compared to endothelial keratoplasty techniques, and results in significant induced astigmatism.
• DSEK (Descemet Stripping EK): An older partial-thickness technique with slower visual recovery and more corneal scarring than DMEK.
• Best medical management: Hypertonic drops and ointments—which manage symptoms but do not restore clear vision.

S-DMEK now offers these patients a third path: the superior clarity and rapid vision recovery of DMEK, even when endothelial cell counts are borderline or when anatomical challenges would make standard DMEK risky.

Clinical examples where S-DMEK excels:

• Low endothelial cell count: A patient with Fuchs' dystrophy who has a borderline endothelial cell count—below the typical DMEK threshold—becomes a suitable candidate with S-DMEK.
• Previous failed graft: A patient whose first DMEK graft failed due to dislocation can be re-grafted safely with S-DMEK's suture support.
• Anterior chamber lens: A patient who underwent cataract surgery decades ago with an AC IOL can now receive DMEK rather than being relegated to penetrating keratoplasty.
• Corneal scarring and irregular astigmatism: Temporary sutures provide extra control in anatomically challenging corneas.

Dr. Shaarawy's Credentials and Recognition

Dr. Ahmed Shaarawy's expertise is recognized internationally and locally:

• American Academy of Ophthalmology (AAO): Active member; participant in continuing medical education and research initiatives.
• American Society of Cataract and Refractive Surgery (ASCRS): Full member; engaged in the global corneal transplant and refractive surgery community.
• Devers Fellowship Training: Recipient of advanced training from one of North America's leading corneal transplant centers.
• Founder and leader of ESK-CT: Establishes and maintains standards for corneal transplantation across Egypt and the Arab region.

The Road Ahead: S-DMEK and the Future of Corneal Surgery in Egypt

The successful introduction of S-DMEK at cornea.clinic marks a significant milestone not just for Dr. Shaarawy, but for ophthalmology in Egypt. It demonstrates that advanced surgical innovation is no longer the exclusive domain of major medical centers in the United States, Europe, or Australia. With proper training, infrastructure, and commitment to excellence, Egyptian surgeons can pioneer and perform cutting-edge techniques.

As more patients learn about S-DMEK and its advantages, demand for the procedure is expected to grow. Dr. Shaarawy's willingness to master and disseminate this technique may inspire other Egyptian and Arab corneal surgeons to expand their skillsets, ultimately raising the standard of care across the region.

Further, the establishment of ESK-CT provides a formal mechanism for training the next generation of corneal transplant surgeons in Egypt, ensuring that S-DMEK and other advanced techniques become part of the standard curriculum rather than rare exceptions.

Is S-DMEK Right for You?

If you have been diagnosed with corneal endothelial disease—such as Fuchs' dystrophy, pseudophakic bullous keratopathy, or keratoconus with endothelial stress—and have been told that your endothelial cell count is "borderline" for standard DMEK, or if a previous graft has failed, S-DMEK may be an excellent option.

A comprehensive evaluation by a corneal specialist is essential. This includes:

• Specular microscopy to determine endothelial cell count and morphology.
• Anterior segment imaging (slit-lamp, OCT) to assess corneal scarring and anatomy.
• Assessment of previous surgical history and any IOL placement.
• Detailed discussion of expectations, recovery timeline, and potential complications.
