Research and development of laser-based new ophthalmic instruments for therapy and microsurgery using real-time eye tracking and programmed control

Objective



In ophthalmic laser applications, especially in refractive eye surgery (e.g. photorefractive keratectomy), photodynamic therapy and laser iridopuncture, laser radiation must be precisely placed and configured in the operation zone. Real-time eye tracking can increase the efficiency of these procedures, make them patient friendly and obviate the necessity for compulsory eye fixation.

Another problem is programming the topography of the laser irradiation zone. Different zones of an eye are to be irradiated in definite sequence and with predetermined parameters. The optimal laser beam trajectories and configuration, as well as irradiation parameters, are to be computed and controlled within the duration of the procedure.

Therefore, the main points of this project are: to study eye movement characteristics under real conditions of ophthalmic laser procedures; to analyse the consequences of eye movements for the quality of operations; to develop improvements to the technology of laser operations based on eye tracking and control techniques, optical and control systems, hardware and software; to develop, design and manufacture the instruments of the above-mentioned eye tracking and control systems integrated into the operating laser installations; and to recommend possible fields of application of the developed methods.

As a result, the technology of laser photorefractive procedures will be improved. Special attention will be paid to the compatibility of the developed optical and control systems, hardware and software with the available surgical, therapeutic and diagnostic systems. Medical personnel from Kiev will study the technology and clinical aspects of photorefractive procedures in the clinics of Heraklion and Dresden with the aim of their reproduction in Kiev.

Joint teams will use the experience of German and Greek specialists in laser eye microsurgery and the experience of the Kvant Institute in computer-controlled object tracking to develop new technology, and acquire new knowledge and know-how.
