ON THE TECHNIQUE OF LENS NUCLEUS FRACTURE IN PHACOEMULSIFICATION

Xülasə

Purpose – to propose an advanced technique for lens nucleus fracture in phacoemulsification (FE).

Material and methods
The proposed method was tested on 58 patients of the main group, who underwent FE according to an advanced technique (aFE), 56 patients made up the control group with standard FE (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 FE. 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 lens nucleus fracture in FE 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.
