FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine and medical equipment, to ophthalmological, in particular, refraction laser surgery. Apparatus for laser surgery contains source of laser beam, means for positioning beam, emitted by said source for spatial and time control of laser beam movement on operated eye, camera for formation of images of eye iris and pupil and connected to camera software programmable computer for control of beam positioning means in accordance with impact profile and adjusted to installation in the process of eye operation, on the basis of data about images, coming from camera, position of specified point on eye cornea and on coordination of impact profile position with determined position of said point on cornea. Apparatus also contains measuring device, providing computer with measurement results for determination of parameter, characterising depth of operated eye and corresponding to depth of anterior chamber and, if it seems desirable, to cornea thickness. Computer is adjusted to determination on the basis of data about images coming from camera of value of pupil centre displacement and on determination of specified point position on cornea depending on measured parameter, radius of eye rotation and determined value of displacement, characterising direction and amount of pupil centre displacement with respect to reference position of pupil centre. Method of laser surgery is realised with application of said apparatus and lies in the following: laser irradiation is directed at eye or inside eye in accordance with space-time sequence, determined by desirable impact profile, which is adjusted spatially relative to specified point of operated eye. After that, parameter, characterising depth of operated eye and corresponding to depth of anterior chamber and, if it seems desirable, cornea thickness, is measured, at least, one before beginning operation, and control programme for computer is generated.
EFFECT: application of the group of inventions will make it possible to ensure exact positioning of laser beam in the process of ophthalmological laser operation.
