Thessaloniki Vision Clinic is a specialized ophthalmology center in Thessaloniki, Greece. Its focus is corneal transplants, glaucoma surgery, and refractive vision correction. For layered corneal grafts, it reports a rejection rate of just 1%. Dr. Panagiotis Dervenis leads the clinic. He is a clinical researcher with over 25 publications in leading journals. These include Eye (Nature) and the British Medical Journal. He holds the FEBO diploma from the European Board of Ophthalmology.
Dr. Dervenis completed specialized training at Moorfields Eye Hospital in the United Kingdom. He has also practiced at King's College Hospital in London. Cataract surgery is a day procedure done with local anesthetic drops. This small-incision technique uses ultrasound energy and needs no stitches. For vision correction, advanced laser platforms support LASIK, PRK, and SMILE. The team uses femtosecond laser technology for maximum surgical accuracy.
