Corneal Surgery

When it comes to corneal surgery in Zurich, the ELZA Institute has the expertise to give you the highest standard of care. We have global experts like Prof. Farhad Hafezi, Dr. Lamis Baydoun and Dr. Emilio Torres-Netto who have many years of experience with corneal diseases and surgeries. We regularly welcome guest surgeons at ELZA and we have taught many other surgeons in Europe and around the world to perform these procedures. This is why patients come from all over Switzerland – and the world – to ELZA for advanced corneal assessments and cornea surgery in Zurich.

Corneal Surgery: Pterygium Removal

A pterygium often creates a large amount of traction on the cornea. The resulting irregular astigmatism reduces visual quality, something we can fix. We remove the pterygium using the latest no-stitch free conjunctival transplantation techniques. Then, we smoothen and regularize the corneal surface to improve your vision.

Corneal Surgery: Salzmann Degeneration

These nodules are collagen deposits on the cornea that can distort the cornea, make it less transparent or both. We have a long-standing experience of surgically removing Salzmann nodules. Later, we smoothen the corneal surface using an excimer laser to improve your vision.

Improving vision after Radial Keratotomy (RK)

Radial keratotomy was a surgical treatment in the 1980s and 1990s, before the modern excimer lasers were developed. Deep cuts were performed in the cornea to correct for myopia. Unfortunately, many of the patients treated now suffer from long-term consequences that are hard to treat. The ELZA Institute has invented a new surgical approach that may reverse the over-flattening that occurs in many patients who had previously undergone radial keratotomy (RK) surgery, in a procedure called STARK.

Improving Terrien’s Marginal Degeneration (TMD)

TMD is a disease where the cornea gets thinner and thinner and the periphery, with drastic changes in vision. The ELZA Institute were the first in the world to successfully treat Terrien Marginal Degeneration with CXL.

Corneal infection

Corneal infection with bacteria, fungi or parasites (called infectious keratitis) is one of the leading causes of global blindness. ELZA members are the pioneers of PACK-CXL – photoactivated chromophore for keratitis-CXL – a treatment for corneal infections that does not depend on antibiotics or antifungal drugs to kill pathogens. We were able to show in a large multinational study led by us that a single treatment of PACK-CXL is as effective as multiple days of hourly antibiotic treatment to treat small to mid-size infectious ulcers.

Cornea and hormonal changes

Has your vision changed and are you pregnant or do you suffer from changes in your thyroid gland? Several hormones such as estrogen and thyroid hormone can change the stability of the cornea. Our surgeons and researchers have worked extensively on this topic, which has been integrated into the “EyeWiki” of the American Academy of Ophthalmology, read here.

Corneal Surgery: Corneal transplantation

The ELZA Institute has two world-renowned corneal surgeons: Dr. Lamis Baydoun, and Dr. Emilio Torres-Netto. They are experts in performing several types of corneal transplantation surgery in Zurich, including full-thickness corneal transplants (penetrating keratoplasty), lamellar transplants, and DMEK for Fuchs’ dystrophy and Cornea guttata.

I have been to the ELZA clinic to have surgery for my miopy, as my eyes were rejecting the contacts and I was tired of... wearing glasses. From the first preliminary visit, to the actual surgery and post-surgery care Dr. Hafezi and all his collaborators have been extremely professional, considerate and helpful. All the steps of the (very short!) surgery were thoroughly explained to me in order to be as calm as possible, together with the medication plan and precautions to be aware of so that my eyes could heal in the best way possible. By following their exact instructions, the healing process has been very successful and smooth, and after about one week I was able to see perfectly. I absolutely recommend this team and their expertise!read more

After some research on local options I decided to go with ELZA since it stood out as the best. The operation and the... post-operation recovery went extremely smooth (something I was worried about with PRK). Now my vision is much better than I had hoped and I have no side effects such as dry eye or night vision problems. Thank you!read more

Vor einem Jahr war ich einer ganz verzweifelten Situation und total im Stich gelassen. Meine Augen wurden aufgrund... eines ausgeprägten Kerakotonus immer schlechter, ich hatte Angst und war alleine mit meinen Problemen. Zudem vertrug ich die Kontaktlinsen nur noch ganz schlecht und hatte jeden Tag Schmerzen.Professor Hafezi hat mir mit zwei Operationen wieder das auf Grund der Situation mögliche an Lebensqualität zurückgebracht. Es war ein starpaziöses Jahr mit vielen Entbehrungen aber es hat sich gelohnt! Herzlichen Dank fuer die Unterstützung.read more

Ich wurde von meiner Optikerin auf Prof. Dr. Dr. Hafezi aufmerksam gemacht. Es war mir vorher nicht bewusst, dass meine... Augenkrankheit (Keratokonus) operativ mittels Cross Linking behandelt und so gestoppt werden kann. Die Beratung und Behandlung war sehr kompetent und ich fühlte mich jederzeit wohl. Die Operation verlief gut und das Ergebnis ist einwandfrei.read more

My left eye had to be operated on because of a cataract. As I had an Artiflex lens implanted a few years ago, it had to... be removed first before a modern lens could be implanted to correct the cataract. Prof. Hafezi treated me in an very competent and friendly manner. I am very happy with the result.read more

At the moment, 3 months have passed since the moment I made laser vision correction in this clinic. and I can say that... I am happy that I chose this particular clinic and Prof. F. Hafezi. The entire staff of the clinic is very friendly, treats patients with sympathy and patience if they are nervous before surgery (my big gratitude to Aida Alili for all support and patience). The doctor Hafezi and other doctors of the clinic are very professional and ready to explain to you as many times as you need. I can only recommend!read more

The day I had Prof Hafezi checking my keratoconus I knew I was finally in the right place after years of searching for... a good ophthalmologist. Prof Hafezi recommended a surgery due to a drastic degeneration of my cornea. The surgery was performed by himself with the assistance of Dr Rodriguez, one more collaborator of Prof Hafezi’s team who got my full trust.read more
