Abstract
Purpose. To modify the technique of nucleus fracture during cataract phacoemulsification (PE). Material and methods. The proposed method was tested on 58 patients of the main group, who underwent PE according to an advanced technique (aPE), 56 patients made up the control group with standard PE (phacochop). All the patients underwent a conventional comprehensive ophthalmological examination. Results. There was a reduction in the total (in average by 39.0 %) and torsion (by 33.3 %) ultrasound time (US), aspiration time (by 26.1 %), as well as the number of intra- and postoperative complications – from 6.1 % to 9.2 % – compared with standard PE. The density of endothelial cell turned out to be lower: after 1 month – by 136.42 and 154.49 с/mm2, after 1 year – by 174.14 versus 206.64, respectively. Conclusion. The proposed technique of nucleus fracture in PE helps to reduce the total time of energy load and the time of torsion ultrasound, as well as the aspiration time, which contributed to a decrease in intra- and postoperative complications by 1.5 times compared with the standard technique. Keywords: cataract phacoemulsification, modified technique of nucleus fracture, reduction of energy load on ocular tissue, reduction of complications
