Research, Awards, Publications and Editorial Activities
His research interests expand in all fields of ophthalmology, including refractive surgery, visual optics, medical lasers, biopolymers, retinal surgery and image analysis, and the design and development of microsurgical instrumentation. While today he has a broad field of interests, his most significant impact is in refractive surgery, in which he is considered internationally as one of the most opinionated leaders. At his early years, he published three breakthrough articles related to the development and investigation of laser in situ keratomileusis (LASIK). Since then, he had a great impact in the field of ophthalmology while today he is considered “the father of LASIK”, the most world wide acknowledged and used technique in refractive surgery today. In many countries LASIK is the most frequent surgical operation on the human body (followed by cataract surgery). Prof. Pallikaris has published approximately 198 articles in international peer-reviewed scientific journals and 27 articles in national peer-reviewed scientific journals. He is the editor of 5 books in ophthalmology, the most notable one being the book LASIK, a reference point for refractive surgeons worldwide. Moreover, he is the author or co-author of 17 invited chapters in International scientific books, while he is a reviewer in 5 international peer-reviewed journals. He has more than 2264 citations, an h-factor of 24, while he holds more than 20 patents. In addition, he has been an invited speaker in more than 200 international conferences from 1998-2011, has over 240 and 170 presentations in international and Greek conferences, respectively. Finally, he has been awarded 15 international awards, most notably the “Barraquer award” from the American Academy of Ophthalmology (1997) for his groundbreaking contribution to refractive surgery. Recently, he completed editing a book on prebyopia (Presbyopia: Origins, Effects, and Treatment. Authors: Ioannis Pallikaris, W. Neil Charman, Sotiris Plainis - ISBN-10: 1617110264) that is to be published in June 2012.
Memberships, conference organization, and educational activities
Due to his worldwide recognition in the field of refractive surgery and research activities in the field of ophthalmology, he has been a member and in some a founder of 28 national and international scientific committees, elected president of the European Society of Cataract and Refractive Surgery (2006 – 2008), elected vice president of the National Board of Research and Technology (ESET) and a member of the Greek National Committee of Unesco. Moreover, he is the coordinator of two conferences on a biannual basis in collaboration with the Harvard Medical School, and one summer school in Visual Optics on an annual basis. Furthermore, he has been the principal advisor of 25 PhD theses and more recently the coordinator of the interdisciplinary postgraduate program entitled Vision and Optics, in collaboration with the department of Physics, Mathematics and Materials Science of the University of Crete. In addition, he has been the organizer of both fellowships and mini fellowships in refractive surgery since 1998 with the participation of over 59 Greek and 40 international ophthalmologists. Finally, he has been the coordinator of 25 competitive research grants, 13 of which have been awarded by the European Union and 12 funded by the Greek National General Secretariat of Research and Technology, while he has also been the coordinator of 2 self-funded research programs and has participated in 3 FDA trials.
In summary, Prof. Pallikaris had a remarkable contribution and has been essential in reforming the field of ophthalmology in the present days. His initial contribution in refractive surgery and his development of the most word wide used technique in our days was a major breakthrough that has changed the course of history in ophthalmology today. His work had a great impact on newly developed and investigated techniques most of which evolve around his initial thoughts on refractive surgery. Alternative refractive procedures such as photorefractive keratectomy with or without the adjuvant of mitomycin C, LASEK, wavefront and topo-guided corrections are closely related to his initial and innovative ideas. Most recently, he developed a new technique (epi-LASIK) where the epithelial layer of the cornea is manipulated as a whole by means of a purposely-designed device, bringing microsurgery of the eye to the cellular scale.
His strive for excellence has lead to a significant contributions in other fields related to ophthalmology, the foundation of a multidisciplinary center related to vision science, and the transfer of knowledge that may be reflected on his students and educational activities. Besides medical doctors, his research group includes experienced scientists from fields such as Engineering, Optics, Physics, Computer programming, Materials Science, Vision Science and Biology in order to accomplish the most significant step in refractive surgery today: Presbyopia
Prof. Pallikaris has been essential in expanding the revolutionary field of refractive surgery and creating the appropriate grounds for the opening of new and exciting applications in this field. His initial contributions with the development of LASIK had a direct impact on the newly formed, developed and investigated techniques today. Concurrently, the development of this groundbreaking technique had an enormous effect not only on the surgical field but also on the technological aspects of the associated instrumentation. Nonetheless, he continued to educate himself and support alternative fields in ophthalmology related to vision as a whole and not just from the medical view of the field. Moreover, Prof. Pallikaris and his collaborators implement a number of clinical investigations in collaboration with various medical companies as part of mutual research protocols. Some of these research protocols were performed for the US Food and Drug Administration with very important outcomes for the safety, reliability and effectiveness of new systems used in Ophthalmology. In addition, clinical protocols are performed in animal models for the development of new therapeutic methods (i.e. photodynamic therapy), the assessment of possible toxic effects of various new drugs and the understanding of the factors that influence post- laser treatment corneal transparency.
In terms of systems, devices and instruments used in ophthalmology, he is contributing to this field by designing and developing new specialized instruments and systems. The TRACEY device, developed in collaboration with the Kiev Institute of Biomedical Technology (Ukraine) was one of the first commercial instruments for the measurement of the optical aberrations of the human eye and the assessment of retinal image quality. Under his guidance a precision machining workshop was deployed in the Institute of Vision and Optics of the University of Crete. It is remarkable, that the most experienced (and well equipped) machining workshop in the whole University of Crete belongs to the department of Ophthalmology. This workshop, following a quality control system in compliance to ISO 9001 is performing R&D and small scale manufacturing work (also irrelevant to ophthalmology) for other departments and the local industry.
Apart from the expansion and inclusion of researchers in a variety of fields such as physics, optics, and engineering, he has strongly supported and provided a spark for new and younger scientists to accomplish their goals within the field of ophthalmology. Many of the graduates and post graduates students have gone to highly successful areas nationally and internationally and have contributed significantly to the scientific community. As it was mentioned earlier, education constitutes one of the basic activities of IVO as it fulfills its academic mission. Mini Fellowships in refractive surgery addressed towards ophthalmologists, optometrists, and opticians, conference organizations such as the Aegean Cornea and Aegean Retina with the participation of distinguished scientists, the interdisciplinary postgraduate program with the contribution of IVO and the collaboration of the departments of Medicine, Physics, and Mathematics of the University of Crete with the objective of the formation of scientists with a high level of education capable to follow careers in hospitals, medical centers, private enterprises that develop and implement devices in the fields of visual science, as well as in Universities and Research Institutes as academic – research personnel, are examples of the educational activities that he has initiated.
