Dr Ioannis Tzouganakis DVM BSAVA PGCertSAOphthal MRCVS




Ioannis graduated from the University of Thessaly in Greece. His passion for ophthalmology began to develop when he was an undergraduate student. After graduation, he spent a year at one of the largest referral hospitals in Athens working with one of Greece’s foremost ophthalmologists before moving to the United Kingdom. Having spent a few years in general practice, during which he further improved his knowledge in veterinary ophthalmology by successfully completing the Postgraduate Certificate in Small Animal Ophthalmology, he joined Davies Veterinary Specialists in 2017 for a rotating internship followed by an ophthalmology internship to pursue further specialisation in ophthalmology. In 2018 he joined the ophthalmology team at Davies Veterinary Specialists as a resident of the European College of Veterinary Ophthalmology.

Always being keen to improve his knowledge and stay up to date with the most recent advancements in his field, Ioannis participates in multiple conferences and wet labs around Europe and the United Kingdom every year. Ioannis enjoys all aspects of ophthalmology but he is particularly keen on surgery and reconstructive techniques of corneal injuries.
