| description | Purpose: to compare two types of phacoemulsification parameters (combination ultrasound and torsional US with IP) with estimating the number of postoperative complications caused by intraoperative trauma of corneal endothelial cells.Patients and methods. 72 patients underwent phacoemulsification with IOL implantation. Patients were randomly divided into two groups (main n = 33 and control n = 39). During the aspiration of lens fragments in the main group the combination ultrasound was used, while torsional US with IP was used in the control group. Endothelial cell counting and other examinations were performed 1 day, 1 week and 6 months after the surgery.Results. CDVA in the explored groups 1 week after the surgery was similar: the main group — 0.813 ± 0.228, the control group — 0.765 ± 0.250, There was also no statistically significant difference in the thickness of the cornea between the groups: the main group — 533.48 ± 12.41, the control group — 536.44 ± 10.92. At the same time, a statistically significant difference was found in the density of endothelial cells: the main group: 1871.30 ± 187.41 (after 1 week), 1865 ± 178.9 (after 6 months); control group: 1809.63 ± 225.43 (after 1 week), 1791 ± 230.82 (after 6 months). The percentage of cell loss was, respectively, lower in the main group at all times of observation: 3.90% (after 1 day), 4.54% (after 1 week), 4.9% (after 6 months). In the control group: 7.71% (after 1 day), 9.25% (after 1 week), 10.4% (after 6 months).Conclusions. Data obtained in this study has showed the advantages of combination ultrasound in comparison with torsional US with IP, when performing aspiration of dense lenses. Due to lower consumption of ultrasound energy and higher aspiration rate of the fragments, combination ultrasound can reduce the loss of corneal endothelial cells and decrease the number and severity of postoperative complications associated with it. |
