The researcher C. Bacharis has professional experience since 1991 in the field of refraction syrgery with excimer lasers (correction of myopia, astigmatism, hyperopia and recently presbyopia), as on duty Phycisist for the appropriate operation of these laser systems that are used for such treatments. He also participated in the planning and the application of protocols of the treatments as scientific responsible collaborator at many ophthalmological centers in Greece. He has also been trained many times with various laser systems all around the world concerning the application of them on the cornea. His knowledge, which acquired from his doctoral thesis, is particularly important on issues of phasmatoscopic analysis of trace elements with use of laser beams, also been enriched during research programmes such as Pythagoras II in which he was the main researcher. In the frames of this program there have taken place experiments of deconstruction in simulators of human cornea like PMMA and hydrophilic intraocular lenses and on pig cornea, ex vivo. Today he continues his research on the study of phenomena which take part in the interaction of laser beams on cornea (mainly for the correction of presbyopia) as well as on polymers-biocompatible materials with the human eye with the aim of the creation of customized intraocular lenses for the complete correction of all refraction eye problems and the hypervision achievement.
