N2  - The high prevalence of cataracts necessitates the development of advanced technologies in ophthalmic microsurgery. A research team has introduced an innovative hydrodynamic scheme designed to increase the safety of phacoemulsification procedures. This system detects occlusion by monitoring the vacuum levels in the aspiration line; when a critical threshold is reached and sustained, the system detects the occlusion and gradually reduces the vacuum to a predetermined value, all while maintaining occlusion. This study aimed to investigate morphological changes in the corneal tissue of rabbit eyes following experimentally induced post-occlusion waves using this novel hydrodynamic scheme. A total of 32 eyes from 16 white laboratory rabbits were studied. Both the conventional technology and the new hydrodynamic model were employed, using phaco needles of different diameters. The corneal samples were subjected to histological examination under light microscopy. The results showed that the least corneal damage occurred in group 4, where the innovative hydrodynamic scheme was combined with a fine needle (diameter = 0.9 mm). These findings suggest that this novel system can significantly reduce corneal trauma during phacoemulsification.
