Patient Reviews
Through patients' eyes
I had cataract surgery with a trifocal IOL last week — a smart 3D lens was implanted. Within a week I was back to my social life, and my eye now sees 100%. Prof. Dr. Coşkunseven is an excellent doctor, and his treatment technique is excellent too. Don't hesitate — get treated right away.
You have been in our prayers since 2009, dear Professor. When everyone was recommending surgery for my sibling's keratoconus, we were fortunate to find you by chance — and fortunate that in 2009 you treated my sibling with the ring implant method instead.
Dear Professor, what a miracle it is to see the world — you touched my life so beautifully and transformed my quality of life overnight. I'm so glad our paths crossed, so glad you exist. You performed both the cataract and the lens surgery in a single procedure and had me feeling better in a day.
May you be blessed with a long and healthy life, Dr. Efekan. May those healing hands of yours keep working miracles.
May you be granted a long life, and may you reach many more happy years together with your loved ones, God willing. Greetings to the Balkans from Manusha, Kosovo.
You are a wonderful person, both in your work and your character. May God be pleased with you. Love from Siirt.
I wish you continued success. It's fortunate that you're in Turkey — we can find you anywhere. You are a truly invaluable doctor in whom I have complete trust. We love you very much.
Hello Professor, I'm out of town. Five years ago you performed intraocular lens surgery on my right eye and laser treatment on my other eye, and I was very pleased with the result. Your warm, attentive manner felt like that of an older brother, like a father. You are so valued, Professor.
Dear Professor, in 2003 you performed laser treatment on my eyes and my world lit up. I now live in the Netherlands. I'd also like my son to have the same procedure. Thank you, Professor. Greetings from the Netherlands.
Hello Professor, I am your keratoconus patient. You lit up my world — I pray for you every day.
