Abstract

The aim was to study the dependence of senile cataract phacoemulsification (PE) parameters on hydrodissection (HD) features.

Materials and methods. 64 patients (64 eyes) who underwent PE of senile cataract using either viscodissection (VD) (main group) or regular HD (control group). Time parameters — VD and HD duration, cortex aspiration, and total time of PE, — along with calculation of mean volume of BSS in both groups were studied.

Results. It took 1.8 times more time to perform VD compared to HD duration. The cortex aspiration step required 2.4 times less time in the eyes of main group in comparison with control group, as 10 eyes (31.2%) of the main group had spontaneous full cortex evacuation through ultrasound tip at epinucleus removal. Other 22 eyes (78.8%) of the main group needed aspiration of cortex, which occupied 1/6–1/3 capsule circumference. Though surgery time was comparable in both groups, mean volume of BSS spent was justifiably 1.5 times higher in the control group.

Conclusion. Performed analysis showed that VD is an effective method which provides optimization of PE of senile cataract. Use of VD allowed exclusion of cortex aspiration in 31.2% of eyes in the main group and decrease of its duration by 2.4 times in comparison with the control group.
