The problem of cataract prevalence makes it necessary to develop innovative technologies for eye microsurgery. An innovative hydrodynamic scheme has been developed by a team of researchers. Its essence lies in the fact that when the vacuum level in the aspiration line reaches critical figures and remains at this level for a specified time, the system recognizes this state as occlusion and smoothly reduces the vacuum to a preset value while maintaining occlusion. The purpose of this scientific study is to study morphological changes in the cornea of rabbits' eyes after experimental modeling of a post-occlusion wave using a new hydrodynamic scheme of a phaco-emulsifier. The study was conducted on 32 eyes of 16 white laboratory rabbits, using traditional technology and an innovative hydrodynamic scheme, as well as needles of various diameters. The pieces of the cornea were carefully examined using a light microscope. The least damage to the cornea of the eye was found in the fourth group of rabbits, where an innovative hydrodynamic scheme was used in combination with a thin needle d = 0.9 mm.
