Oganes G. Oganesyan

Ophthalmologist, Associate Professor,
Doctor of Medical Sciences, highest qualification category.
The first and only NIIOS*-certified corneal transplant specialist in the post-Soviet region
(2006, 2008, 2018).

My name is Oganes G. Oganesyan. I am a doctor and ophthalmic surgeon. For me, ophthalmology is more than a job: it is a way of life. I developed a passion for the subject and began learning its foundations in my first year of medical school. I graduated with honours. For 28 years, my professional career was based at one of Russia’s oldest and leading institutions, the Helmholtz Eye Research Institute. There I completed my clinical residency and postgraduate research training (1996–2001), defended my Candidate of Medical Sciences dissertation in 2001 on ‘Autologous Conjunctival Grafting of the Cornea in Emergency Corneal Surgery’, and subsequently defended my Doctor of Medical Sciences dissertation in 2011 on ‘A System of Surgical Rehabilitation for Patients with Corneal Endothelial Dystrophy’.
My Professional Journey
I progressed through the roles of Research Fellow, Senior Research Fellow, and Leading Research Fellow.
From 1998 to 2024, I served on the on-call surgical team at the Helmholtz Eye Research Institute, providing round-the-clock surgical care for a wide range of ophthalmic emergencies. During this time, I completed more than 700 twenty-four-hour shifts, performed over 170 microsurgical procedures for traumatic injuries, reconstructive operations on the eye and emergency corneal transplants, and removed more than 100 intraocular foreign bodies.
My years at the Helmholtz Institute inevitably involved complex clinical cases and situations requiring quick, precise decisions. This experience taught me responsibility, respect for every patient and their interests, and the importance of continuing to learn and develop without hesitation.
Over the course of my work, I have performed more than 1,000 corneal transplants using various techniques (PK, DALK, ALK, invALK, DMEK, DSEK, FS-invDSEK, ¼-DMEK, ½-DMEK, ¾-DMEK, BL onlay, BL inlay, DM onlay, DM inlay, FS-ALT, and others), and more than 5,000 phacoemulsification procedures with implantation of various intraocular lenses (IOLs), including premium IOLs.
Thirty years of practice have given me extensive experience in ophthalmic surgery, the surgical treatment of eye injuries, and the management of complex clinical cases, including patients with only one seeing eye.
In 2006, I had the honour of being the first to introduce and promote modern corneal endothelial transplantation in Russia (Vestnik Oftalmologii, 2006; see publications).
I am the only specialist in Russia performing Bowman layer transplantation for keratoconus and certain other corneal conditions. I am also the only specialist in Russia performing partial DMEK (hemi-DMEK, Q-DMEK, and ¾-DMEK), including in eyes with corneal dystrophy and glaucoma drainage devices.
I was fortunate to be the first and only specialist from Russia to train repeatedly with G. Melles himself, the developer of modern endothelial surgery (see documents), at NIIOS in Rotterdam, a leading centre for modern corneal transplantation. For almost 20 years, I have continued research and publishing collaborations with him and his colleagues (see publications).
I have twice received grants from the German Ophthalmological Society (DOG), won Best Presentation awards at international conferences on several occasions, and undertaken multiple clinical placements in Germany and the Netherlands. I regularly present and perform live demonstration surgery at conferences.
Since 2017, I have taught as a professor in the Departments of Ophthalmology at the Yevdokimov Moscow State University of Medicine and Dentistry and Tver State Medical University. I give approximately 40 lectures a year to ophthalmologists and residents. I am an author or co-author of 16 Russian patents (see patent list).
I have written three teaching guides and one textbook on corneal transplantation, and co-authored the Clinical Atlas of Eye Trauma.
I have more than 250 publications in leading Russian and international journals (see publications). In 2021, I was awarded the academic title of Associate Professor (see documents).
I am a visiting lecturer, professor, and leading surgeon at Crystal Vision, Bahrain Specialist Hospital (BSH), in the Kingdom of Bahrain.
I have completed eight half marathons (21 km) and eight marathons (42 km):
Saint Petersburg (2015)
Rotterdam (2016)
Los Angeles (2017)
Paphos (2018)
New York (2021)
New York (2022)
Sochi (2023)
Moscow (2025).
I completed a swim across the Volga in 2022, four 113 km IRONMAN events in Sochi (2020), Kazan (2021), Sochi (2021), and Sevan (2022), and a full 226 km IRONMAN in Sochi (2023).
My journey in ophthalmology spans 30 years of clinical practice, research, and teaching. I have performed operations ranging from standard procedures to rare and technically demanding interventions. This experience underpins my professional development and interest in the latest, least invasive surgical treatments.
My main areas of work are cataract and lens surgery and corneal transplantation (DSEK, DMEK, DALK, PK, and others). I was among the first to introduce these techniques into clinical practice, trained with international experts, and adapted the methods to real clinical situations.
I regularly take part in professional conferences and training programmes and continue to learn, because medicine keeps moving forward and doctors must continue to develop. In combining clinical surgery, research, and teaching, I hold to one central principle: the quality of treatment matters more than the number of patients.
Why I Chose Ophthalmology
Why I Became a Doctor
I cannot remember the exact moment I made that decision. For as long as I can remember, I wanted to be a doctor. Ophthalmology, however, was something I ‘inherited’: through the gentle, wise influence and invaluable example of my mother, a wonderful ophthalmologist, physician, and surgeon, and my first and most important teacher in the field. From my first year at university, I wanted to study ophthalmology at the renowned Helmholtz Research Institute in Moscow. From 1996 to 2001, I completed fee-paying clinical residency and postgraduate research training. My knowledge, dedication, qualities, and skills were recognised by the renowned Professor Roza A. Gundorova, who invited me to remain at the Helmholtz Institute. I was proud to work, learn, teach, and treat patients there, and in 2024 I was happy to move on.
A Journey Through Difficulties
Looking back on my years at Yerevan Medical University, I feel proud, even if that may sound immodest. I studied with excellent results, thoroughly and diligently, with what I can only describe as dedication. I feel proud because I did so by candlelight and kerosene lamps, as circumstances in the country required at the time, often in the cold, surrounded by stacks of library books, regularly giving up time with friends, without the internet, computers, Google Translate, or similar resources.
My Approach to People
My professional teachers shaped my approach to relationships. I aim to build my relationships with patients on cooperation, empathy, and respect. I do not favour paternalism between doctor and patient. In relationships with colleagues, I value mutual respect, professionalism, and cooperation. I prefer independence to rigid hierarchy, and personal responsibility to collective responsibility.
My Values and Working Principles
Professionalism and competence
Responsibility
Personal development and lifelong learning
Mutual respect and trust
First, do no harm
Empathy and patience
  • Being available around the clock.

Patient Reviews
Ekaterina M.
I had cataract surgery on both eyes, in 2021 and 2024. Dr Oganesyan is a wonderful doctor: incredibly attentive, kind-hearted, and responsible. You immediately feel complete trust in him, and your fear disappears. He is so determined to help everyone that he practically runs through the department. Thank you for your kindness, refinement, and quiet sense of humour. Thank you for your brilliant surgical hands. I work as an accompanist at a music school and spend all day reading music carefully. I also often perform on stage. Because of my eyesight, I thought I would have to give up the work I love and retire. Now everything is wonderful. I read music, read books, and sew without glasses. Dr Oganesyan planned everything so skilfully that I do not need glasses outdoors either. Thank you, Doctor!
He is incredibly attentive, kind-hearted, and responsible. You immediately feel complete trust in him, and your fear disappears.

I first met Dr Oganesyan in 2023 when I needed a corneal transplant. I can confidently say that he is not only an excellent medical professional, but also a warm person who truly cares about his patients. What matters is that he looks beyond the immediate problem and chooses the best treatment approach to help. I am immensely grateful for his outstanding professionalism, sensitivity, attentiveness, and dedication to the work he loves. At a difficult time in my life, I was incredibly fortunate to find such a competent, talented, and caring doctor. My family and I thank him wholeheartedly for guiding us through this journey.
I. N. Butenko
My son has a very difficult problem with his eyesight — an extremely complex one, to be precise. We asked Dr Oganesyan for help, and he helped us. He performed a corneal transplant in 2019 and lens replacement on 22 August 2024. He is an exceptionally professional doctor.
With gratitude and great respect, I. N. Butenko, Belgorod Region.
L. M. Gafarova
Dear Dr Oganesyan, thank you for your outstanding professionalism, approachability, patience, attentiveness, friendliness, and sense of humour, which helps ease the tension. You not only treat our eyes, which is so important, but also heal our souls. Thank you, thank you so much.
Dr Oganesyan performed cataract surgery on my right eye in May 2022 and on my left eye in April 2024.
Yours sincerely, L. M. Gafarova, patient.
Irina V.
My husband was the patient. After his consultation, he underwent lens replacement surgery. His vision improved considerably, and he began to distinguish objects. The doctor has golden hands! His professionalism, care for his patient, attentiveness, precision, and warmth were truly impressive. It was after the consultation that we began to believe my husband would be able to see again — and that is exactly what happened!

Why Trust Me with Your Surgery?

If I were choosing a doctor, I would trust someone who combines many years of experience and thousands of operations with modern techniques, attentive patient care, scientific work, and personal availability.
I aim to explain everything in plain language and support each patient at every stage, from the first consultation to full recovery.
I am not saying that you must have your surgery with me: the decision is yours. But I strongly recommend choosing your doctor carefully. People choose their hairdresser; choosing a doctor deserves even greater care.
Everyone has different selection criteria. The facts below may help you decide whether to consult Oganes G. Oganesyan.
1. Advanced Qualifications
Based on more than 25 years of medical and surgical experience and supported by academic qualifications, training certificates, the highest physician qualification category (see documents), publications (see publication list), and other credentials.
2. My Core Principles of Patient Care
Explain complex matters clearly and simply.
Allow time for communication, listen carefully, and build an equal, cooperative dialogue without overfamiliarity or paternalism.
Speak honestly about the patient’s condition, progress, expected results, possible complications, and outcomes.
Personally consult, speak with, and examine patients before surgery.
Personally operate on my patients.
Personally examine, speak with, and assess patients after surgery.
Oversee treatment personally from beginning to end.
Remain personally available and in contact with patients, without intermediaries or assistants.
I am ready to consult patients after their treatment with me, however much time has passed since surgery. I aim to avoid a rigid, formulaic approach and to remain creative, flexible, and attentive to individual needs.
My priorities are the patient’s health and satisfaction, treatment quality, patient trust, professionalism, and reputation.
3. A Unique Specialist in Russia and the Former Soviet Countries
The only specialist in Russia and the former Soviet countries to have trained repeatedly, starting in 2006, with Gerrit Reinold Jacob Melles, the originator of modern endothelial transplantation techniques, at the Netherlands Institute for Innovative Ocular Surgery in Rotterdam, a leading centre for modern corneal transplantation (see certificates).
4. Among the First Surgeons Worldwide to Perform DMEK, Starting in 2008
I began performing DMEK in 2008, among the first surgeons worldwide, after my first training course with the technique’s developer, G. Melles (see related publications: ‘Initial Experience with Descemet Membrane Transplantation’. Ophthalmology. 2008;5(4):18–22; and ‘Multicenter study of Descemet membrane endothelial keratoplasty: first case series of 18 surgeons’. JAMA Ophthalmol. 2014 Oct;132(10):1192–8. doi:10.1001/jamaophthalmol.2014.1710).
5. Extensive, Long-Standing Experience in DMEK, DSEK, and Bowman Layer Transplantation
This includes complex cases. Having adopted these procedures early, I have some of the longest patient follow-up periods worldwide after such operations.
6. Equal Expertise in Corneal Transplantation, Lens Surgery, and Reconstructive Surgery
Years of experience in ocular trauma and cataract surgery have refined my skills in microsurgery, suturing, and reconstructive procedures and shaped my approach to medication-based treatment. This enables me to work equally confidently with corneal transplantation techniques requiring sutures (penetrating keratoplasty and DALK) and sutureless techniques (DMEK, DSEK, BLT, and others), including when combined with complex lens surgery.
7. More Than a Practising Ophthalmic Surgeon Since 1996
I also:
Conduct research (Candidate and Doctor of Medical Sciences, Associate Professor).
Teach as a professor in a Department of Ophthalmology.
Train residents, postgraduate researchers, and practising ophthalmologists.
Publish actively in leading journals (see publication list).
Develop innovations (see patents and publications).
Supervise and advise several postgraduate researchers.
Serve as an official opponent at dissertation defences.
Review manuscripts for leading journals.
Together, these activities help me maintain my qualifications, stay engaged in research, follow international ophthalmic literature, learn and introduce the latest innovations and technologies into practice, develop my professional skills, and continually learn, teach, draw on others’ experience, and share my own.
8. Regular Conference Participant, Speaker, and Expert
For many years, I have attended Russian and international conferences not only as an active participant and listener, but also as a speaker, expert, and opinion leader, often chairing or co-chairing specialist ophthalmology sessions (see conference participation list).
9. A Commitment to Professional, Conscientious Work and Attentive, Friendly Care for Every Patient. This Is Not a Guarantee of the Outcome.
The outcome depends not only on the surgeon but also on many other factors, often beyond the doctor’s control. We all need to understand clearly that nothing in life, medicine, and especially surgery can be guaranteed. To better understand the doctor–patient relationship, it is helpful to consider the word ‘guarantee’ in other areas of life. Think of a flight: imagine the surgeon as the pilot and the patient as the passenger.
10. A Passion for Sport Helps Me Maintain Discipline
Including at work, sport helps me maintain endurance, patience, productivity, and mental and physical health. It supports a positive attitude towards life, work, patients, and colleagues, and encourages empathy, responsibility, kindness, and communication skills.
If you are reading this, the way you are treated matters to you as well as the quality of your surgery.
Attention, professionalism, reassurance, and honesty are what I aim to offer every patient.
